  • Qt Object Linker Problem " undefined reverence to vtable"

    - by Thomas
    This is my header: #ifndef BARELYSOCKET_H #define BARELYSOCKET_H #include <QObject> //! The First Draw of the BarelySocket! class BarelySocket: public QObject { Q_OBJECT public: BarelySocket(); public slots: void sendMessage(Message aMessage); signals: void reciveMessage(Message aMessage); private: // QVector<Message> reciveMessages; }; #endif // BARELYSOCKET_H This is my class: #include <QTGui> #include <QObject> #include "type.h" #include "client.h" #include "server.h" #include "barelysocket.h" BarelySocket::BarelySocket() { //this->reciveMessages.clear(); qDebug("BarelySocket::BarelySocket()"); } void BarelySocket::sendMessage(Message aMessage) { } void BarelySocket::reciveMessage(Message aMessage) { } I get the Linker Problem : undefined reference to 'vtable for barelySocket' This should mean, i have a virtual Function not implemented. But as you can see, there is non. I comment the vector cause that should solve the Problem, but i does not. The Message is a complex struct, but even converting it to int did not solve it. I searched Mr G but he could not help me. Thank you for your support, Thomas

  • TinyMCE + jQuery + custom plugin = tinymce is undefined?

    - by user368691
    The problem occurs when I try to create small plugin to allow me toggle on and off WYSIWYG on all textareas in the website. //$('form.default textarea').each(function(){ // console.log( $('<a href="#">Enable WYSIWYG editor</a>').insertAfter('form.default textarea').prev('textarea.wysiwyg').tinymce().hide() ); //}); The full (a bit simplified) code looks like this: $('textarea.wysiwyg').tinymce({ skin : 'cirkuit', theme : 'advanced', plugins : 'pagebreak,style,layer,advlink,inlinepopups,contextmenu,paste,directionality,noneditable,nonbreaking,xhtmlxtras,template', // Theme options theme_advanced_buttons1 : 'formatselect,fontsizeselect,forecolor,|,bold,italic,strikethrough,|,bullist,numlist,|,justifyleft,justifycenter,justifyright,|,link,unlink,|,image,|,code,paste,pastetext,pasteword,removeformat,|,backcolor,|,underline,justifyfull,sup,|,outdent,indent,|,hr,charmap,|,undo,redo', theme_advanced_buttons2 : '', theme_advanced_buttons3 : '', theme_advanced_toolbar_location : 'top', theme_advanced_toolbar_align : 'left', theme_advanced_statusbar_location: 'bottom', theme_advanced_resizing : true, theme_advanced_resize_horizontal : false, height : 500, theme_advanced_resizing_min_height : 500, document_base_url : 'http://static.<?=$settings['system_host']?>/' }); $('textarea.wysiwyg').each(function() { $(this).tinymce().hide(); }); What is the error? FireBug says that tinymce() in undefined; this message occurs in each() loop. Thus, tinymce() is actually initialized. I am really lost towards, what could be causing this.

  • Probably an easy one - PHP/CodeIgniter 'Undefined Variable'

    - by Jack W-H
    Morning y'all This is probably an easy one but I barely got any sleep last night and am struggling to comprehend anything. I've got a CodeIgniter library I've made called Points.php. Here's the contents of Points: <?php if (!defined('BASEPATH')) exit('No direct script access allowed'); class Points { function __construct() { $this->ci =& get_instance(); $this->ci->load->database(); } function getpoints($params) { echo $userid; } } /* End of file Points.php */ /* Location: ./application/libraries/Points.php */ ?> As you can see, I'm building it up slowly and it's being kept simple. In one of my views, I want it to display the number of 'points' (which for the time being is simply the third segment of the URI). I call it like this: <p>Points: <?php $params['user_id']=$this->uri->segment(3,1); echo $this->points->getpoints($params); ?></p> The warning I get back in the view is this: A PHP Error was encountered Severity: Notice Message: Undefined variable: userid Filename: libraries/Points.php Yes I know it's such a simple problem but I've tried lots of things. Some variations include echoing in Points.php $params['userid']; etc. But I don't see what I'm doing wrong? This is my first CodeIgniter class and I've fallen at the first step, haha...

  • Get "term is undefined” error when trying to assign arrayList to List component dataSource

    - by user1814467
    I'm creating an online game where people log in and then have the list of current players displayed. When the user enters a "room" it dispatches an SFSEvent which includes a Room object with the list of users as User objects in that room. As that event's callback function, I get the list of current users which is an Array, switch the View Stack child index, and then I wrap the user list array in an ArrayList before I assign it to the MXML Spark List component's dataSource. Here's my code: My Actionscript Code Section (PreGame.as): private function onRoomJoin(event:SFSEvent):void { const room:Room = this._sfs.getRoomByName(PREGAME_ROOM); this.selectedChild = waitingRoom; /** I know I should be using event listeners * but this is a temporary fix, otherwise * I keep getting null object errors * do to the li_users list not being * created in time for the dataProvider assignment **/ setTimeout(function ():void { const userList:ArrayList = new ArrayList(room.userList); this.li_users.dataProvider = userList; // This is where the error gets thrown },1000); } My MXML Code: <?xml version="1.0" encoding="utf-8"?> <mx:ViewStack xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" initialize="preGame_initializeHandler(event)" > <fx:Script source="PreGame.as"/> <s:NavigatorContent id="nc_loginScreen"> /** Login Screen Code **/ </s:NavigatorContent> /** Start of Waiting Room code **/ <s:NavigatorContent id="waitingRoom"> <s:Panel id="pn_users" width="400" height="400" title="Users"> /** This is the List in question **/ <s:List id="li_users" width="100%" height="100%"/> </s:Panel> </s:NavigatorContent> </mx:ViewStack> However, I keep getting this error: TypeError: Error #1010: A term is undefined and has no properties Any ideas what I'm doing wrong? The arrayList has data, so I know it's not empty/null.

  • PHP - warning - Undefined property: stdClass - fix?

    - by Phill Pafford
    I get this warning in my error logs and wanted to know how to correct this issues in my code. Warning: PHP Notice: Undefined property: stdClass::$records in script.php on line 440 Some Code: // Parse object to get account id's // The response doesn't have the records attribute sometimes. $role_arr = getRole($response->records); // Line 440 Response if records exists stdClass Object ( [done] => 1 [queryLocator] => [records] => Array ( [0] => stdClass Object ( [type] => User [Id] => [any] => stdClass Object ( [type] => My Role [Id] => [any] => <sf:Name>My Name</sf:Name> ) ) ) [size] => 1 ) Response if records does not exist stdClass Object ( [done] => 1 [queryLocator] => [size] => 0 ) I was thinking something like array_key_exists() functionality but for objects, anything? or am I going about this the wrong way?

  • twitter bootstrap typeahead (method 'toLowerCase' of undefined)

    - by mmoscosa
    I am trying to use twitter bootstrap to get the manufacturers from my DB. Because twitter bootstrap typeahead does not support ajax calls I am using this fork: https://gist.github.com/1866577 In that page there is this comment that mentions how to do exactly what I want to do. The problem is when I run my code I keep on getting: Uncaught TypeError: Cannot call method 'toLowerCase' of undefined I googled around and came tried changing my jquery file to both using the minified and non minified as well as the one hosted on google code and I kept getting the same error. My code currently is as follows: $('#manufacturer').typeahead({ source: function(typeahead, query){ $.ajax({ url: window.location.origin+"/bows/get_manufacturers.json", type: "POST", data: "", dataType: "JSON", async: false, success: function(results){ var manufacturers = new Array; $.map(results.data.manufacturers, function(data, item){ var group; group = { manufacturer_id: data.Manufacturer.id, manufacturer: data.Manufacturer.manufacturer }; manufacturers.push(group); }); typeahead.process(manufacturers); } }); }, property: 'name', items:11, onselect: function (obj) { } }); on the url field I added the window.location.origin to avoid any problems as already discussed on another question Also before I was using $.each() and then decided to use $.map() as recomended Tomislav Markovski in a similar question Anyone has any idea why I keep getting this problem?! Thank you

  • 'JQuery' is undefined

    - by Raja
    I am working on a ASP.net project created with local file system settings. I am using MVC and Jquery. Jquery is working fine when I run the application in debug mode i.e. in ASP.net Development server. I am trying to host the application in IIS 7. In hosted mode, it does not recognize Jquery and gives scripting error 'Jquery is undefined'. The locations of the script files is unchanged in both modes. Can anybody have any clue what can be the reason and how to solve this.

  • undefined references

    - by Brandon
    Hello, I'm trying to compile some fortran code and I'm running into some confusing linking errors. I have some code that I compile and place into a static library: >gfortran -c -I../../inc -o bdout.o bdout.F >ar rv libgeo.a bdout.o I then try to compile against that library with some simple test code and get the following: >gfortran -o mytest -L -lgeo mytest.F /tmp/cc4uvcsj.o: In function `MAIN__': mytest.F:(.text+0xb0): undefined reference to `ncwrite1_' collect2: ld returned 1 exit status It's not in the object naming because everything looks fine: >nm -u libgeo.a bdout.o: U _gfortran_exit_i4 U _gfortran_st_write U _gfortran_st_write_done U _gfortran_transfer_character U _gfortran_transfer_integer U ncobjcl_ U ncobjwrp_ U ncopencr_ U ncopenshcr_ U ncopenwr_ U ncwrite1_ U ncwrite2_ U ncwrite3_ U ncwrite4_ U ncwritev_ I can check the original object file too: >nm -u bdout.o U _gfortran_exit_i4 U _gfortran_st_write U _gfortran_st_write_done U _gfortran_transfer_character U _gfortran_transfer_integer U ncobjcl_ U ncobjwrp_ U ncopencr_ U ncopenshcr_ U ncopenwr_ U ncwrite1_ U ncwrite2_ U ncwrite3_ U ncwrite4_ U ncwritev_ The test code simply contains a single call to a function defined in bdout.o: program hello print *,"Hello World!" call ncwrite1( istat, f, ix2, ix3, ix4, ix5, ih ) end program hello I can't figure out what the problem is.

    - by floatingfrisbee
    I'm trying to install Community Engine using the instructions here: http://github.com/bborn/communityengine At first I thought it might be because I had Rails 2.3.5 and desert 0.5.3 which were higher versions than what was mentioned on the installation site.

  • Microsoft JScript runtime error: '(function name)' is undefined

    - by Velika2
    Microsoft JScript runtime error: 'txtGivenName_OnFocus' is undefined After adding what I thought was unrelated javascript code to a web page, I am suddenly getting errors that suggest that the browser cannot locate a javascript function that, to me, appears plain as day in design mode. I'm thinking that this is a load sequence order problem of some sort. Originally, my script was at the bottom of the page. I did this with the intent of helping my site's SEO ranking. When I moved the function to the top of the web page, the error went away. Now it is back. I have a feeling someone is going to suggest a jQuery solution to execute some code only when the page is fully loaded. I'm I ignorant of jQuery. IfjQuery is given in the answer, please explain what I need to do (references, placement of script files) for VS 2010 RTM. I am trying to set the focus to the first textbox on the webpage and preselect all of the text in the textbox More info: If I disable this Validator, the problem goes away: <asp:CustomValidator ID="valSpecifyOccupation" runat="server" ErrorMessage="Required" ClientValidationFunction="txtSpecifyOccupation_ClientValidate" Display="Dynamic" Enabled="False"></asp:CustomValidator> function txtSpecifyOccupation_ClientValidate(source, args) { var optOccupationRetired = document.getElementById("<%=optOccupationRetired.ClientID %>"); if (optOccupationRetired.checked) { args.IsValid = true; } else { var txtSpecifyOccupation = document.getElementById("<%=txtSpecifyOccupation.ClientID %>"); args.IsValid = ValidatorTrim(txtSpecifyOccupation.value) != ""; } }

  • jQuery ajaxForm "h is undefined" problem

    - by Simon
    I have a form that is brought up in a ajaxed modal which I am using for updating user details. When the modal loads I call a js function: teamCreate: function() { $j("#step1,form#createEditTeam").show(); $j("#step2").hide(); var options = { type: "get", dataType: 'json', beforeSubmit: before, // pre-submit callback success: success // post-submit callback }; $j("form#createEditTeam").ajaxForm(options); function before(formData, jqForm, options){ var valid = $j("form#createEditTeam").valid(); if (valid === true) { $j(".blockMsg").block({ message: $j('#panelLoader') }); return true; // submit the form } else { $j("form#createEditTeam").validate(); return false; // prevent form from submitting } }; function success(data){ if (data.status == "success") { $j(".blockMsg").unblock(); } else { // } }; function error(xhr, ajaxOptions, thrownError){ alert("Error code: " + xhr.statusText); }; } This works just fine when I first submit the form, regardless how many times the modal is opened and closed. However, if I submit the form and then open the modal again and try to submit the form again I get a js error: h is undefined

  • Objects in JavaScript defined and undefined at the same time (in a FireFox extension)

    - by Alexey Romanov
    I am chasing down a bug in a FireFox extension. I've finally managed to see it for myself (I've only had reports before) and I can't understand how what I saw is possible. One error message from my extension in the Error Console is "gBrowser is not defined". This by itself would be surprising enough, since the overlay is over browser.xul and navigator.xul, and I expect gBrowser to be available from both. Even worse is the actual place where it happens: line 101 of nextplease.js. That is, inside the function isTopLevelDocument, which is only called from onContentLoaded, which is only called from onLoad here: gBrowser.addEventListener(this.loadType, function (event) { nextplease.loadListener.onContentLoaded(event); }, true); So gBrowser is defined in onLoad, but somehow undefined in isTopLevelDocument. When I tried to actually use the extension, I got another error: "nextplease is not defined". The interesting thing is that it happened on lines 853 and 857. That is, inside the functions nextplease.getNextLink = function () { nextplease.getLink(window.content, nextplease.NextPhrasesMap, nextplease.NextImagesMap, nextplease.isNextRegExp, nextplease.NEXT_SEARCH_TYPE); } nextplease.getPrevLink = function () { nextplease.getLink(window.content, nextplease.PrevPhrasesMap, nextplease.PrevImagesMap, nextplease.isPrevRegExp, nextplease.PREV_SEARCH_TYPE); } So nextplease is somehow defined enough to call these functions, but isn't defined inside them. Finally, executing typeof(nextplease) in Execute JS returns "object". Same for gBrowser. How can this happen? Any ideas?

  • ruby on rails: undefined method "version_requirements' when attempting to start server after new install

  • response.Text is undefined when returning variable

    - by George
    Not sure if the problem is related to Ajax or something silly about JavaScript that I'm overlooking in general, but I have the following script where fox.html is just plain text that reads, "The quick brown fox jumped over the lazy dog." : function loadXMLDoc() { if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","fox.html",true); xmlhttp.send(); xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { fox = xmlhttp.responseText; alert(fox); } } } onload = loadXMLDoc; The above script alerts the contents of fox.html onload just fine. However if I change the script so that: { fox = xmlhttp.responseText; alert(fox); } becomes: { fox = xmlhttp.responseText; return fox; } and alert(loadXMLDoc()); onload I get 'undefined'. I'm wondering why this is so.

My js code looks like this: $.ajax({ type: "POST", url: "Data/RealTime.ashx", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", timeout: 15000, dataFilter: function(data, type) { alert("RAW DATA: " + data + ", TYPE: "+ type); return data; }, error: function(xhr, textStatus, errorThrown) { alert("FAIL: " + xhr + " " + textStatus + " " + errorThrown); }, success: function(data) { alert("SUCCESS"); } }); My ajax source is a generic ASP.NET handler: [WebService(Namespace = "http://my.website.com")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class RealTime : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = "application/json"; context.Response.Write("{ data: [1,2,3] }"); context.Response.End(); } public bool IsReusable { get { return false; } } } Now, if I return an empty object ("{ }") in my handler, the call will succeed. But when I return any other JSON object, the call fails. The dataFilter handler shows that I am receiving a correct object. Firebug shows the response as expected, and the JSON tab shows that the object is parsed correctly. So what could be the cause?

  • Undefined variable error when parsing json

    - by Ben Shelock
    I'm trying to parse the json grabbed from here. Basically what I do is iterate over the items, sort them, then display them. But I get an error saying data.data.children[i] is undefined. I can't think why it's doing it though? var json = 'http://www.reddit.com/reddits/mine/.json'; GM_xmlhttpRequest({ method: "GET", url: json, onload: reddits }); function reddits(response){ var txt = response.responseText; var data; var suggested = document.getElementById('suggested-reddits'); if(window.JSON && JSON.parse){ data = JSON.parse(txt); } else{ data = eval("("+txt+")"); } suggested.innerHTML += '<span>reddits you\'re subscribed to </span> <ul id="rsub"></ul>'; GM_addStyle('#rsub{width: 500px;}'); var reddits = new Array(); var rsub = document.getElementById('rsub'); for(i = 0; i <= data.data.children.length; i++){ var r = data.data.children[i].data.display_name; reddits.push(r); } sort(reddits); for(i = 0; i <= reddits.length; i++){ rsub.innerHTML += '<li><a href="#" onclick="set_sr_name(this); return false">' + reddits[i] + '</a></li>'; } }

  • PHP Notice: Undefined property: stdClass:

    - by 4D
    I've got an array coming back from a Flash app created in Flash Builder 4. I have a service setup that queries and brings data back from the DB successfully, however the Update script is generating the Undefined Property errors. I'm still learning both PHP and Flash Builder, and don't fully understand what the $this- commands do. If anyone can suggest where this script is going wrong, it is basically just generated by Flash Builder and is not something I've developed myself, I would appreciate it? Also if someone can explain $this- to me that would be awesome too? I've seen them before, but then I've seen scripts doing the same thing that do not use them, so is this an old way of doing things? Really appreciate any input anyone can give. public function updateItem($item) { // TODO Auto-generated method stub // Update an existing record in the database and return the item // Sample code \' $this->connect(); $sql = "UPDATE tbltrust SET inst_code = '$item->inst_code', trust_name = '$item->trust_name', trust_code = '$item->trust_code' WHERE trust_key = '$item->trust_key'"; mysqli_query($this->connection, $sql) or die('Query failed: ' . mysqli_error($this->connection)); mysqli_close($this->connection); }

  • PHP, is_array() generating an "Undefined property: stdClass::$crit " error

    - by Brook Julias
    is_array($src2->crit) is generating an "Undefined property: stdClass::$crit" error. The line throwing the error is: if(is_array($src2->crit) && count($src->crit) > 0){ $src2->crit is initialized here. $src2->crit = array(); $src2->crit[0] = new dataSet(); $src2->crit[0]->tblName = $tbl2; $src2->crit[0]->colName = "ID"; $src2->crit[0]->val = $elm->editID; When testing $src2->crit with this code. print("\$src->crit is a ".$src->crit."<br />"); print_r($src->crit); print("<br />"); This is returned. $src2->crit is a Array Array ( [0] => dataSet Object ( [tblName] => sExam [colName] => ID [val] => 10 ) ) What am I not seeing/understanding correctly? If print("\$src2->crit is a ".$src->crit."<br />") returns that it is an array then why is is_array($src2->$crit) generating an error?

  • Newbie question: undefined local variable or method , why??

    - by Mellon
    I am new in Rails (I am using Rails 3.0.3), currently I am following the book "Agile Web Development with Rails" to develop a simple rails application. I followed the book to: --create a model 'Cart' class; --implement 'add_to_cart' method in my 'store_controller', I have a line of code <%=button_to "Add to Cart", :action => add_to_cart, :id => product %> in my /store/index.html.erb As you see, there is :action => add_to_cart in my index.html.erb, which will invoke the add_to_cart method in my *Controllers/store_controller.rb* But after I refresh the browser, I got the error "undefined local variable or method 'add_to_cart'", apparently I do have the method add_to_cart in my 'store_controller.rb', why I got this error??? What is the possible cause??? Here are my codes: store_controller.rb class StoreController < ApplicationController def index @products = Product.find_products_for_sale end def add_to_cart product = Product.find(params[:id]) @cart = find_cart @cart.add_product(product) end private def find_cart session[:cart] ||= Cart.new end end /store/index.html.erb <h1>Your Pragmatic Catalog</h1> <% @products.each do |product| -%> <div class="entry"> <%= image_tag(product.image_url) %> <h3><%=h product.title %></h3> <%= product.description %> <div class="price-line"> <span class="price"><%= number_to_currency(product.price) %></span> <!-- START_HIGHLIGHT --> <!-- START:add_to_cart --> **<%= button_to 'Add to Cart', :action => 'add_to_cart', :id => product %>** <!-- END:add_to_cart --> <!-- END_HIGHLIGHT --> </div> </div> <% end %> Model/cart.rb class Cart attr_reader :items def initialize @items = [] end def add_product(product) @items << product end end

  • Clearly defined Rails routing problem - undefined method for Nil:NilClass

    - by sscirrus
    Guys and girls, I have been working on this problem for a while but still no joy. This is my second question within this general area, because the last question was getting too long and this is now more well-defined. Summary of the Problem: I am loading a page for my customers and I get error: undefined method 'name' for Nil:NilClass My Code #Link on views/users/show.html.erb: <%= link_to "Customer Account", :action => "home", :controller => "customers", :id => @user.user_type_id %> #Regular Route: map.connect 'customers/home/:id', :controller => 'customers', :action => 'home' #Rake Routes, first entry: /customers/home/:id :controller=>:"customers", :action=>"home" #Customers Controller: def home render :layout => 'home' @customer = Customer.find(params[:id]) @user = @current_user_session.user flash[:error] = "Customer not found" and return unless @customer @jobs = @customer.jobs end #views/customers/home.html.erb: <%= @customer.name %> I have absolutely no idea why this seemingly clear sequence of events is resulting in a NilClass. Search the console for Customer.find(2) returns the correct customer. What is this noob missing? Thank you very much.

    Hello there, I have the following problem. The alert allways returns undefined, but I know it has a value. What am I doing wrong. I'm out of solutions... I'm using JQUERY jquery-1.4.2.min.js Tnx in advance $(document).ready(function(){ $('#generateButton').click(createIBAN); }); function createIBAN(){ //---- First check if a bank has been selected, //---- if not, then show error if($('#selectBank').val()==''){ alert('Selecte a bank!'); }else{ var bankAccount = generateBankAccount(); alert(bankAccount); } return false; } function generateBankAccount(){ //---- Create "elfproef" bankaccount var bankAccount = ''; //---- Set the amount of digits in a bankaccount digitAmount = 9; //---- Make random digitstring for (var i = 0; i < digitAmount; i++) { bankAccount += Math.floor(Math.random() * digitAmount); } //---- validate the string, if not "elf-proef" if (elfProef(bankAccount)==false) { //---- regenerate the string generateBankAccount(); }else{ return bankAccount; } } function elfProef(bankAccount) { //---- set sum to 0 and start the for-loop for counting var sum = 0; for (var i = 0; i < digitAmount; i++) { //---- for every digit multiply it times 9 - number //---- of the digit and count it to the sum var sum += bankAccount.charAt(i) * (digitAmount - i); } //---- Check if sum can be devided by 11 without having ##,## if(sum % 11==0){ //---- return true means string is "elf-proef" return true; }else { //---- String is not "elf-proef", try again return false; } }

  • X-Forwarded-For causing Undefined index in PHP

    - by bateman_ap
    Hi, I am trying to integrate some third party tracking code into one of my sites, however it is throwing up some errors, and their support isn't being much use, so i want to try and fix their code myself. Most I have fixed, however this function is giving me problems: private function getXForwardedFor() { $s =& $this; $xff_ips = array(); $headers = $s->getHTTPHeaders(); if ($headers['X-Forwarded-For']) { $xff_ips[] = $headers['X-Forwarded-For']; } if ($_SERVER['REMOTE_ADDR']) { $xff_ips[] = $_SERVER['REMOTE_ADDR']; } return implode(', ', $xff_ips); // will return blank if not on a web server } In my dev enviroment where I am showing all errors I am getting: Notice: Undefined index: X-Forwarded-For in /sites/webs/includes/OmnitureMeasurement.class.php on line 1129 Line 1129 is: if ($headers['X-Forwarded-For']) { If I print out $headers I get: Array ( [Host] => www.domain.com [User-Agent] => Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 [Accept] => text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 [Accept-Language] => en-gb,en;q=0.5 [Accept-Encoding] => gzip,deflate [Accept-Charset] => ISO-8859-1,utf-8;q=0.7,*;q=0.7 [Keep-Alive] => 115 [Connection] => keep-alive [Referer] => http://www10.toptable.com/ [Cookie] => PHPSESSID=nh9jd1ianmr4jon2rr7lo0g553; __utmb=134653559.30.10.1275901644; __utmc=134653559 [Cache-Control] => max-age=0 ) I can't see X-Forwarded-For in there which I think is causing the problem. Is there something I should add to the function to take this into account? I am using PHP 5.3 and Apache 2 on Fedora

  • undefined returned for currentView object in Backbone.Marionette

    - by ontk
    I am testing how a layout can listen to its subviews's custom events. I created a jsFiddle here where I have a layout, 2 regions and I instantiated 2 ItemViews and showed them in the layout's regions. The fiddle is in CoffeeScript. <div id="region"></div> <script id="layout-tmpl" type="text/_"> <h3>Heading</h3> <div id="content"></div> <div id="content2"></div> </script> <script id="item-tmpl" type="text/_"> <form> <label>Firstname:</lable> <input type="text" name="firstname" value="<%= firstname %>" /> <input type="button" value="Save" id="save" /> </form> </script> And the CoffeeScript is: SimpleLayout = Backbone.Marionette.Layout.extend template: '#layout-tmpl' regions: main: '#content' other: '#content2' initialize: () -> console.log @ onShow: () -> _.each @.regionManagers, (region, name, something) => console.log region.currentView # @.bindTo region.currentView, "custom:event", @callback callback: () -> alert "HELL YEAH" SimpleItemView = Backbone.Marionette.ItemView.extend template: "#item-tmpl" events: 'click #save': 'save' save: (evt) -> evt.preventDefault() @.trigger "custom:event" region = new Backbone.Marionette.Region el: "#region" layout = new SimpleLayout() region.show layout layout.main.show new SimpleItemView model: (new Backbone.Model firstname: "Olivier") layout.other.show new SimpleItemView model: (new Backbone.Model firstname: "Travis") I want the layout to listen to the ItemViews's custom events. In the onShow, I am looping through the region managers and trying to access the currentView object but it returns undefined. If I attach the same event handlers outside of the SimpleLayout class and after I show the itemviews, then the layout handlers the custom events properly. Thanks for your help.
