• Strange Behaviour with Unicode Characters in Windows

  - by open_sourse

  Ok, I do not know if this is a programming question, but it certainly is a technical one so I am asking it here. I was working on some internationalization stuff in my PHP code, and in order to ensure that my generated HTML shows up Unicode correctly based on the encoding and stuff I decided to add some Chinese text to my PHP page, which then echoes it into the browser to complete my test case. So I went into google and typed "Chinese", copied the first Chinese text that the search returned (which was ??/??). I then copied it into Notepad++ which is my editor, and to my surprise showed up as boxes similar to [][]/[][]. So I thought the encoding in Notepad++ was messed up and I changed the encoding to UTF-8 and UCS, neither worked. I did it fresh in a newly encoded file, still I got the boxes. The same content when I paste into Google and StackOverFlow (like I did in this posting) shows up correct Chinese! I even opened up Windows Clipboard Viewer and the content is represented in the Clipboard as boxes! I tried pasting it into Windows Explorer address bar and using to rename a file to, but I still get boxes. But it shows up correctly when pasted into my Chrome Browser address bar! Is this a Windows issue? Since I am able to paste it correctly in SO, the data in memory should be encoded correctly right? But if that is the case why does it show up as boxes in the Clipboard Viewer? I am confused here...By the way I am using Windows XP with SP3. (I am asking this question here, even if it is not programmatic, because it is preventing me from running my programming test cases..)

• jquery png fix on hidden div and jquerybrowser question

  - by Jared

  Hello, I have some code that if Javascript is available, it will remove a GIF image and replace it with a PNG image. The PNG is display:none and the GIF is visible. Since IE6- browsers can't load PNG, I have loaded the jquery PNG fix. But it only seems to work if the image is already visible. The other issue is I am trying to get the jquery.browser function to apply to less than version 6, and I am not having much luck. <script type="text/javascript"> $(document).ready(function(){ $("#gif").hide(); jQuery.each(jQuery.browser, function(i, val) { if($.browser.msie && jQuery.browser.version <="6"){ $("#png").show(); $('.png').pngFix() }else{ $("#png").fadeIn("slow"); } }); }); </script> HTML <img class="png" id="png" src="images/main_elements/one-2-flush-it-campus-challenge.png" style="display:none;" /> <img id="gif" src="images/main_elements/one-2-flush-it-campus-challenge.gif"/>

• jsf messed up links

  - by Mateusz

  I'm new to JSF. My application is working, but I'm confused with links in browser when using controller. BTW, there is also PrimeFaces in my app so don't be suprised with p: tags. Let's say I have 'list' and 'show' pages with controller doing redirection between them. First I'm on http://localhost:8080/y/r/conversation/list.xhtml page. There is link created with line <p:commandLink action="#{lazyConversationBean.doShow(conv)}" ajax="false" value="View"/>. lazyConversationBean acts here as my Controller. There is method: public String doShow(Conversation c) { this.setSelectedConversation(c); return "view"; } from which I got redirected to ...... again http://localhost:8080/y/r/conversation/list.xhtml (browser shows it) even when it's correct http://localhost:8080/y/r/conversation/view.xhtml page. There I have link <p:commandButton action="#{lazyConversationBean.doList()}" ajax="false" value="Back to list"/> and again controller has method: public String doList() { return "list"; } from which I got redirected to ... yeah, you guessed right ... http://localhost:8080/y/r/conversation/view.xhtml (that is again what browser shows) even when again it is correct http://localhost:8080/y/r/conversation/list.xhtml page. It seams as browser link area is always one step behind page currently being displayed. I don't even know if it's some incorrect behaviour as I have no idea how to query google for this :D Just for test I did this short tutorial, where netbeans created whole stack of code on one of my entities, and behaviour was the same, so it's not PrimeFaces magic related. Can you tell my why it happens, and how to fix it? Users likes to copy correct links ;)

• Python/Sqlite app for web or desktop?

  - by ChrisC

  I am in the planning stages of rewriting an Access db I wrote several years ago in a full fledged program. I have very slight experience coding, but not enough to call myself a programmer by far. I'll definitely be learning as I go, so I'd like to keep everything as simple as possible. I've decided on Python and SQLite for my program, but I need help on my next decision. Here is my situation 1) It'll be a desktop program, run locally on each machine, all Windows 2) I want a nice looking GUI with colors, different shaped buttons, nice menus, lists, etc, etc 3) I'm thinking about using a browser interface because (a) from what I've read, browser apps can look really great, and (b) I understand there are lots of free tools to assist in setting up the GUI/GUI code with drag and drop tools, so that helps my "keep it simple" goal. 4) I want the program to be totally portable so it runs completely from one single folder on a user's PC. If I do go the browser app router, a major concern I have is the possibility that a user's browser settings could affect or break the app. How likely is this? What other pros and cons are there for my situation?

• Subversion gives Error 500 until authenticating with a web browser

  - by Farseeker

  We used to use Collabnet SVN/Apache combo on a Windows server with LDAP authentication, and whilst the performance wasn't brilliant it used to work perfectly. After switching to a fresh Ubuntu 10 install, and setting up an Apache/SVN/LDAP configuration, we have HTTPS access to our repositories, using Active Directory authentication via LDAP. We're now having a very peculiar issue. Whenever a new user accesses a repository, our SVN clients (we have a few depending on the tool, but for arguments sake, let's stick to Tortoise SVN) report "Error 500 - Unknown Response". To get around this, we have to log into the repo using a web browser and navigate 'backwards' until it works E.G: SVN Checkout https://svn.example.local/SVN/MyRepo/MyModule/ - Error 500 (bad) Webbrowse to https://svn.example.local/SVN/MyRepo/MyModule/ - Error 500 (bad) Webbrowse to https://svn.example.local/SVN/MyRepo/ - Error 500 (bad) Webbrowse to https://svn.example.local/SVN/ - Forbidden 403 (correct) Webbrowse to https://svn.example.local/SVN/MyRepo/ - OK 200 (correct) SVN Checkout https://svn.example.local/SVN/MyRepo/MyModule/ - Error 500 (bad) Webbrowse to https://svn.example.local/SVN/MyRepo/MyModule/ - OK 200 (correct) SVN Checkout https://svn.example.local/SVN/MyRepo/MyModule/ - OK 200 (correct) It seems to require authentication up the tree, starting from the svnparentpath up through to the module required. Has anyone seen anything like this before? Any ideas on where to start before I ditch it back to Collabnet's SVN server?

• Is browser based wireless authentication secure?

  - by johnnyb10

  Our wireless network previously used a preshared WPA/WPA2 key for guest access, which allows them access to the Internet. (Our employee access uses 802.1x authentication). We just had a wireless consultant come in to fix various wireless issues we had; one of the things he wound up doing was changing our guest access to HTML-based instead of the preshared key. So now that guest SSID is open (instead of using WPA) and users are presented with a browser-based login screen before they can get on the Internet. My question is: Is this an acceptable method from a security standpoint? I would assume that having an open network is necessarily a bad idea, but the consultant said that the traffic is still using PEAP, so it's secure. I didn't get a chance to question him further on this because we ran late and a bunch of other things came up. Please let me know what you think about the advantages/disadvantages of using HTML-based wireless authentication as opposed to using a preshared WPA key. Thanks...

• No internet through a web browser but Skype still works

  - by kim3er

  We get our office broadband through a BT Business Broadband WiFi router. We have a mixture of macs and windows PC/laptops connecting to it at any one time. All devices are able to connect to the wireless signal with pretty much full signal. However, only two computers (one windows, one os x) are able to consistently connect to the internet. The other three (one windows, two os x), while they can always connect to the wifi, exhibit one of three characteristics. No internet at all. Programs like Skype work, but no internet through a browser. Internet works, but with intermittent lag when switching between different sites. I'm assuming while trying to resolve different addresses. Ignoring point 1 for moment, my gut is telling me DNS. It is an up to 20MB line that usually gets to between 13MB and 15MB downstream. The router is capable of dealing with the amount of wireless devices that we're throwing at it. Has anyone got any suggestions for how I might further diagnose this problem (preferably in OS X)?

• jQuery Autocomplete using extraParams to pass additional GET variables

  - by paperclip

  I am referring specifically to the jQuery Autocomplete v1.1 plugin by Jörn Zaefferer [source: http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/] as there seems to be quite a few variations of this plugin. I'm trying to pass additional parameters to the server when the user starts typing because I have multiple fields that I want autocomplete to provide suggestions for. In addition to the query, I want to send the input name attribute to the server but I can't seem to use $(this).attr('name') within the extraParams. My jQuery: $('.ajax-auto input').autocomplete('search.php', { extraParams: { search_type: function(){ return $(this).attr('name'); } } }) This is my HTML. <form method="post" action="#" id="update-form" autocomplete="off"> <ol> <li class="ajax-auto"> <label for="form-initials">Initials</label> <input type="text" id="form-initials" name="initials" /> </li> <li class="ajax-auto"> <label for="form-company">Company</label> <input type="text" id="form-company" name="company" /> </li> </ol> </form> Any suggestions?

• .htaccess - RewriteRules working, but browser address bar displaying full (unfriendly) URL

  - by axol

  Hey there, Haven't been able to find a solution to this around the net or these forums - apologise if I've missed something! My .htaccess RewriteRules are working well - have search-engine and user -friendly links in my web pages, and unfriendly database URLs running hidden in the background. Except when I added a RewriteRule to add "www." to the front of URLs if the user didn't enter it - to ensure only one appears in search engines. Here's what now happening, and I can't figure out why! My friendly URL structure for content is like this, and the database query string uses the first "importantword": www.example.com/importantword-nonimportantword/ .htaccess snippet: Options +FollowSymLinks Options -Indexes RewriteEngine on RewriteOptions MaxRedirects=10 RewriteBase / RewriteRule ^/$ index.php [L] RewriteRule ^(.*)-(.*)/overview/$ detail.php?categoryID=$1 [L] RewriteCond %{HTTP_HOST} !^www.example.com$ RewriteRule ^(.*)$ http://www.example.com/$1 [L] What's happening since I added the last 2 lines: CASE 1: user types (or clicks) www.example.com/honda-vehicle/overview/ - Works correctly - They are taken to the correct page and the browser URL bar says: www.example.com/honda-vehicles/overview/ CASE 2: user types example.com - Works correctly - They are taken to www.example.com and the browser URL bar says: www.example.com CASE 3: user types (or clicks) example.com/honda-vehicles/overview/ i.e. without the prefix "www" - Does NOT work correctly - They are taken to the right page, but the browser URL bar displays the unfriendly URL: www.example.com/detail.php?categoryID=honda I figure there's some issue with the order of the RewriteRules, but it's doing my head in trying to logically step through it and figure it out! Any assistance at all or pointers would be most appreciated!

• jQuery plugin for Event Driven Architecture?

  - by leeand00

  Are there any Event Driven Architecture jQuery plugins? Step 1: Subscribing The subscribers subscribe to the event handler in the middle, and pass in a callback method, as well as the name of the event they are listening for... i.e. The two green subscribers will be listening for p0 events. And the blue subscriber will be listening for p1 events. Step 2: The p0 event is fired by another component to the Event Handler A p0 event is fired to the Event Handler The event handler notifies it's subscribers of the event, calling the callback methods they specified when they subscribed in Step 1: Subscribing. Note that the blue subscriber is not notified because it was not listening for p0 events. Step 3: The p1 event is fired a component to the Event Handler The p1 event is fired by another component Just as before except that now the blue subscriber receives the event through its callback and the other two green subscribers do not receive the event. Images by leeand00, on Flickr I can't seem to find one, but my guess is that they just call it something else in Javascript/jquery Also is there a name for this pattern? Because it isn't just a basic publisher/subscriber, it has to be called something else I would think.

• Slimbox 2 Plugin, jQuery Flickr, and IE8

  - by Nick H.

  Hello, I am currently developing a site that I make use of two jQuery plugins: Flickr jquery plugin (http://code.google.com/p/jquery-flickr/) Slimbox (http://code.google.com/p/slimbox/) The first plugin is used to pull in flickr photos from a specific account. These photos are displayed as thumbnails on the page. I am then using the second plugin to display larger views of these images. Because the flickr photos are fetched when the page loads, I am calling the Slimbox 2 function like this: $(document).ready(function() { $("#Flickr").flickr(); //Call Flickr plugin $(window).bind('load', function() { $("#Flickr a").slimbox();//Call Slimbox2 }); }); On first testing this seemed to have worked perfectly. I tested multiple versions of FireFox, IE7, IE6, and Safari. Everything is great. However, the Slimbox lightbox effest does not work in IE8. However, if I put IE8 into compatibility mode, everything works as expected. I would like to avoid forcing compatibility mode. There are no javascript errors and I am at a loss for testing. Here is a link to a sample: http://www.njhall.com/JRMcCourt-Builders/index.html#ourwork Any advice would be greatly appreciated. Thanks Nick

• Create custom rewrite rule for my WordPress plugin

  - by kitsched

  I'm writing a plug-in for WordPress which in fact will be a separate ordering module (it will be placed in an IFRAME on the site I'm developing as well as others) but with its admin tied into WordPress. I wrote the administration part without too much hassle, however I'm having trouble with the front-end. First of all I'd like my script to be accessible via www.mysite.com/order/ and, as per the WordPress codex, I found I need to place the following code into my main plugin file: add_action('init', 'ta_flush_rewrite_rules'); function ta_flush_rewrite_rules() { global $wp_rewrite; $wp_rewrite->flush_rules(); } add_action('generate_rewrite_rules', 'ta_add_rewrite_rules'); function ta_add_rewrite_rules( $wp_rewrite ) { $new_rules = array("order/(.+)" => "/wp-content/plugins/my-plugin/order.php"); $wp_rewrite->rules = $new_rules + $wp_rewrite->rules; } But it doesn't work and I don't really want to get dirty with .htaccess hacking. Furthermore even if this would work, the order.php file is a separate file from my plugin. This means that I'll have to include some WordPress files in order to have access to the database and other helper classes and functions. That brings us to question number 2: is there a way for the URL to call a function of my plugin to render the order page?

• How to extend an 'unloadable' Rails plugin?

  - by Vitaly Kushner

  I'm trying to write a plugin that will extend InheritedResources. Specifically I want to rewrite some default helpers. And I'd like it to "just work" once installed, w/o any changes to application code. The functionality is provided in a module which needs to be included in a right place. The question is where? :) The first attempt was to do it in my plugin's init.rb: InheritedResources::Base.send :include, MyModule It works in production, but fails miserably in development since InheritedResource::Base declared as unloadable and so its code is reloaded on each request. So my module is there for the first request, and then its gone. InheritedResource::Base is 'pulled' in again by any controller that uses it: Class SomeController < InheritedResource::Base But no code is 'pulling in' my extension module since it is not referenced anywhere except init.rb which is not re-loaded on each request So right now I'm just including the module manually in every controller that needs it which sucks. I can't even include it once in ApplicationController because InheritedResources inherites from it and so it will override any changes back. update I'm not looking for advice on how to 'monkey patch'. The extension is working in production just great. my problem is how to catch moment exactly after InheritedResources loaded to stick my extension into it :) update2 another attempt at clarification: the sequence of events is a) rails loads plugins. my plugin loads after inherited_resources and patches it. b) a development mode request is served and works c) rails unloads all the 'unloadable' code which includes all application code and also inherited_resources d) another request comes in e) rails loads controller, which inherites from inherited resources f) rails loads inherited resources which inherit from application_controller g) rails loads application_contrller (or may be its already loaded at this stage, not sure) g) request fails as no-one loaded my plugin to patch inherited_resources. plugin init.rb files are not reloaded I need to catch the point in time between g and h

• jQuery AutoComplete Plugin not working for JSON Response (sValue.substring is not a function)

  - by Sunday Ironfoot

  I'm trying to use the autocomplete plugin for jQuery (this one http://docs.jquery.com/Plugins/Autocomplete). My server is returning JSON string, which I'm trying to process on the client via AutoComplete plugin's 'parse' and 'formatItem' parameters, like so: $(document).ready(function() { $('.searchBox input.textbox').autocomplete('/DoSearch.aspx', { mustMatch: false, autoFill: true, minChars: 1, dataType: 'json', parse: function(data) { var array = new Array(); for (var i = 0; i < data.length; i++) { array[array.length] = { data: data[i], value: data[i].ID, result: data[i].ID }; } return array; }, formatItem: function(row, i, n) { return row.ID + ': ' + row.Title; } }); }); When I run this I get a 'sValue.substring is not a function' error thrown in Firebug. However, if I stick breakpoints on formatItem and parse function, they are hit as expected and contain valid data it seems. Here is an exact copy 'n' paste of the JSON text that gets returned from the server: [{"ID":140177,"Title":"Food Handling","Code":"J01.576.423.200"},{"ID":140178,"Title":"Food Handling","Code":"J01.576.423.200"},{"ID":140179,"Title":"Brain Infarction","Code":"C10.228.140.300.301.200"},{"ID":140180,"Title":"Cerebral Hemorrhage","Code":"C10.228.140.300.535.200"},{"ID":140182,"Title":"Insulin","Code":"D06.472.610.575"},{"ID":140183,"Title":"Insulin","Code":"D06.472.610.575"},{"ID":140184,"Title":"Insulin","Code":"D06.472.610.575"},{"ID":140186,"Title":"Insulin","Code":"D06.472.610.575"},{"ID":140188,"Title":"Insulin","Code":"D06.472.610.575"},{"ID":140189,"Title":"Sulfonylurea Compounds","Code":"D02.886.590.795"}] Please help, I've already searched Google and StackOverflow for help, but can't find anyone having else this error, cheers!

• Looking for input on GWT / MVP action w/o browser history change

  - by user198313

  Hello there, I am trying to develop a GWT app with the MVP pattern. So far so good except for one specific case of actions: actions that do not change the url (no browser history change). In the GWT MVP pattern, events are sent from presenters, the an app controller catches them and update the browser history. If the history has changed then the view updates. ** MVP with history change (Works well)** Current URL is /list User clicks on contactdelete button. Fire DeleteContactAction event. App controller catches, change history to 'delete' onValueChange is called if (token.equals("delete")) delete contact screen, then delete contact Fire ContactDeletedEvent app controller catches and change the history to list onValueChange is called: contact list refreshes GWT MVP pattern for dialog box w/o history changes ** Issue ** - I use a dialog box and I don't want to change the browser history, so here is the problem: Current URL is /list User clicks on contactdelete button. Contact is deleted Fire ContactDeletedEvent. App controller catches, change history to 'list' **onValueChange is NOT called** because url is already /list and there is no change # problem: contact list does not refresh Question: does anyone know a pattern to implement this in the context of MVP? Any help / idea appreciated.

• Silverlight 4, Out of browser, Printing, Automatic updates

  - by minal

  I have a very critial business application presently running using Winforms. The application is a very core UI shell. It accepts input data, calls a webservice on my server to do the computation, displays the results on the winforms app and finally send a print stream to the printer. Presently the application is deployed using Click-once. Moving forward, I am trying to contemplate wheather I should move the application into a Silverlight application. Couple of reasons I am thinking silverlight. Gives clients the feel that it is a cloud based solution. Can be accessed from any PC. While the clickonce app is able to do this as well, they have to install an app, and when updates are available they have to click "Yes" to update. The application presently has a drop down list of customers, this list has expanded to over 3000 records. Scrolling through the list is very painful. With Silverlight I am thinking of the auto complete ability. Out of the browser - this will be handy for those users who use the app daily. I haven't used Silverlight previous hence looking for some expert advice on a few things: Printing - does silverlight allow sending raw print data to the printer. The application prints to a Zebra Thermal label printer. I have to send raw bytes to the printer with the commands. Can this be done with SL, or will it always prompt the "Print" dialog? Out of browser - when SL apps are installed as out of browser, how to updates come through, does the app update automatically or is the user prompted to opt for update?

• Problem with qTip - Tips not showing because elements load after the script

  - by msvalkon

  Hey, I'm not very experienced with javascript, jQuery or it's plugins but usually I manage. Anyways, my client is building a site and one of its purposes is to pick up news articles from different sites and show the titles in unordered html lists. I don't have access to his code, the news articles load up rather slow(much after the site has loaded). I'm using qTIP and the idea is that once you hover over a news title, it will generate a tooltip. This works fine in my dev environment, because I have dummy title's that are not generated from anywhere. The problem is that once the client sets the site up in his test environment, the scripts that load the news titles into the lists are so slow, that the qTIP-script loads before there are any elements in the lists. Hence it's not aware of any <li>'s to pick up and generate tooltips from. Is there a way make sure that ALL of the news articles are loaded before the tooltip-script loads? I think that a simple delay in loading the script is not very smart because some of the titles seem to take longer to load than others, so the delay would have to be rather long.

• Installing paperclip plugin

  - by mnml

  I'm trying to install the paperclip plugin with the following command: ruby script/plugin install git://github.com/thoughtbot/paperclip.git But I'm getting some errors: ruby script/plugin install git://github.com/thoughtbot/paperclip.git --force svn: '/home/app/vendor/plugins' is not a working copy /usr/lib/ruby/1.8/open-uri.rb:32:in `initialize': No such file or directory - git://github.com/thoughtbot/paperclip.git (Errno::ENOENT) from /usr/lib/ruby/1.8/open-uri.rb:32:in `open_uri_original_open' from /usr/lib/ruby/1.8/open-uri.rb:32:in `open' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:863:in `fetch_dir' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:857:in `fetch' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:856:in `each' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:856:in `fetch' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:219:in `install_using_http' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:169:in `send' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:169:in `install' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:734:in `parse!' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:732:in `each' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:732:in `parse!' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:447:in `parse!' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:463:in `parse!' from ./script/../config/../vendor/rails/railties/lib/commands/plugin.rb:871 from script/plugin:3:in `require' from script/plugin:3 Is it because I'm using a old rails version?

• How can I get jQuery validation plugin Ketchup to stop an Ajax form submission when validation fails?

  - by Marshall Sontag

  I'm using Ruby on Rails, Formtastic gem, jQuery and ketchup to validate my form. I'm submitting the form created by Formtastic inside a modal box using ajax: <% semantic_form_remote_for @contact_form, :url => '/request/contact' do |f| %> I have a validation plugin verifying the fields on the form: $(document).ready(function() { $("#new_contact_form").ketchup(); }); The problem is that semantic_form_remote_for generates an onSubmit ajax request that the jQuery validation plugins won't prevent, since it's not a normal form submission. One question on stackoverflow suggests using :condition on the remote form declaration to fire a javascript function, but I can't do that since I'm not using a function, but rather relying on a jQuery handler. I also tried putting ketchup within a submit event handler: $(document).ready(function() { $("#new_contact_form").submit(function() { $('#new_contact_form').ketchup(); }); }); No luck. Form still submits. I also tried using the beforeSend option of jQuery.ajax: $(document).ready(function() { jQuery.ajax( { beforeSend: function(){ $('#new_contact_form').ketchup(); } }); }); Validation fires off, but form is still submitted. I switched to jQuery Validation plugin just to see if it was due to some limitation in Ketchup. It turns out that Validation has a submitHandler option: $(document).ready(function() { $('#new_contact_form').validate({ submitHandler: function(form) { jQuery.ajax({ data:jQuery.param(jQuery('#new_contact_form').serializeArray()), dataType:'script', type:'post', url:'/request/contact' }); return false; } }); }); This works when I use a regular semantic_form_for instead of semantic_form_remote_for, but alas, I would rather use Ketchup. Is Ketchup just woefully lacking? Am I forced to use jQuery Validation?

• Multiple HTML lines with jquery tooltip plugin

  - by dafi

  I'm using the plugin http://bassistance.de/jquery-plugins/jquery-plugin-tooltip/ to create tooltips with JQuery but I can't created tooltips containing 3 (or more) lines of HTML code. I need to render as tooltip the content shown below (obviously the content is generated dynamically an this it only a proof of concept) <p>Line1</p> <p>Line2 <span style="...">blah blah</span></p> <p>Line3</p> The showBody property seems applicable only to title attributes. Found the problem Apparently jquery.html("...") requires a root tag otherwise generates an empty string. My original code was bodyHandler: function() { return $("<span id='caption'>line1</span>" + "<span id='tags'>line2</span>"); } need to be written with a dummy root tag removed by JQuery bodyHandler: function() { return $( "<root-dummy-tag>" + "<span id='caption'>line1</span>" + "<span id='tags'>line2</span>" + "</root-dummy-tag>" ); }

• Installing and using acts-as-taggable-on

  - by seaneshbaugh

  This is going to be a really dumb question, I just know it, but I'm going to ask anyways because it's driving me crazy. How do I get acts-as-taggable-on to work? I installed it as a gem with gem install acts-as-taggable-on because I can't ever seem to get installing plugins to work, but that's a whole other batch of questions that are all probably really dumb. Anyways, no problems there, it installed correctly. I did ruby script/generate acts_as_taggable_on_migration and rake db:migrate, again no problems. I added acts_as_taggable to the model I want to use tags with, started up the server and then loaded the index for the model just to see if what I've got so far is working and got the following error: undefined local variable or method `acts_as_taggable' for #. I figure that just means I need to do something like require 'acts-as-taggable-on' to my model's file because that's typically what's necessary for gems. So I did that hit refresh and got uninitialized constant ActiveRecord::VERSION. I'm not even going to pretend to begin to know what that means went wrong. Did I go wrong somewhere or there something else I need to do. The installation instructions seem to me like they just assume you generally know what you're doing and don't even begin to explain what to do when things go wrong.

• Autocomplete and IE7 - slowness, sluggishness as overall pagesize grows?

  - by wchrisjohnson

  Hi, I have the autocomplete plugin (http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/, version 1.1 and 1.0.2) on a project to add pieces of "equipment" to a "project". On a fresh project the plugin works great; the data returned from the database comes back FAST, you can scroll the list fast, and can select an item and move on to the next one. Once I have a project established with equipment on it, and I go to add equipment, the performance is pretty bad. It takes 4-5 seconds to get the list of data back from the server, scrolling the list is painful, and the cursor takes several seconds to settle on an item. Repainting the page after the list goes away is slow. This is occurring in IE7, latest version. FF3 and Chrome are fine, very snappy. The pagesize is about 40K overall. I'm thinking this is an issue with the IE7 Javascript engine, or an edge case with this plugin and IE7; it works quickly enough in FF3+. I would appreciate any ideas, solutions, known issues, or thoughts on how to more specifically pin this down. I'd love to post sample code, but this is a corporate app, and I'm not how useful it would be given that the server side piece cannot be shown; ie: you can't pull it down and test it like a self contained piece of code.. Thanks in advance! Chris
