  • Drools Rules: How can I use a method on "when" section?

    - by manoelhc
    Hi, I need to execute a method on "when" section of a DSLR file and I´m not sure if it´s possible. Example: rule "WNPRules_10" when $reminder:Reminder(source == "HMI") $user:User(isInAgeRange("30-100")==true) Reminder(clickPercentual >= 10) User(haveAtLeastOptIns("1,2,3,4") == true) then $reminder.setPriority(1);update($reminder); end (note: isInAgeRange() and haveAtLeastOptIns() are methods of User) I tried with eval() and no errors appeared, but it didn´t execute. Like this: rule "WNPRules_10" when $reminder:Reminder(source == "HMI") $user:User(eval($user.isInAgeRange("30-100")==true)) Reminder(clickPercentual >= 10) User(eval($user.haveAtLeastOptIns("1,2,3,4") == true)) then $reminder.setPriority(1);update($reminder); end How can I resolve this problem?

  • JSF Deferred EL conditional syntax problem

    - by Mark Lewis
    Hello I can't find any resources which can answer why I'm getting an error with this: oncomplete="#{MyBacking.oError ? #{rich:component('oErrorPanel')}.show() : return false;}" in a richfaces a4j:commandButton. oError is referring to a method in my bean called isOError. I'm getting the error SEVERE: Servlet.service() for servlet Faces Servlet threw exception org.apache.el.parser.ParseException: Encountered " "?" "? "" at line 1, column 30.

  • Automatic counter in Ruby for each?

    - by yar
    I know you Ruby people will laugh at my bad Ruby code: i=0 for blah in blahs puts i.to_s + " " + blah i+=1 end I want to use a for-each and a counter... is there a better way to do it? Note: I don't know if blahs is an array or a hash, but having to do blahs[i] wouldn't make it much sexier. Also I'd like to know how to write i++ in Ruby. Edit: Technically, Matt's and Squeegy's answer came in first, but I'm giving best answer to paradoja so spread around the points a bit on SO. Also his answer had the note about versions, which is still relevant (as long as my Ubuntu 8.04 is using Ruby 1.8.6). Edit: Should've used puts "#{i} #{blah}" which is a lot more succinct.

  • Ruby on rails link_to syntax

    - by mizipzor
    After following a tutorial Ive found. Im now redoing it again, without the scaffolding part, to learn it better. However, editing my \app\views\home\index.html.erb to contain: <h1>Rails test project</h1> <%= link_to "my blog", posts_path> I get an error: undefined local variable or method `posts_path' for #<ActionView::Base:0x4e1d954> Before I did this, I ran rake db:create, defined a migration class and ran rake db:migrate, everything without a problem. So the database should contain a posts table. But that link_to command cant seem to find posts_path. That variable (or is it even a function?) is probably defined through the scaffold routine. My question now is; how do I do that manually myself, define posts_path?

    I am getting unexpected T_TRY, expecting T_FUNCTION error message and am not sure as too why am getting that, can't we use try and catch block inside class like this: class Processor { protected $dao; protected $fin; try { public function __construct($file) { //Open File for parsing. $this->fin = fopen($file,'w+') or die('Cannot open file'); // Initialize the Repository DAO. $this->dao = new Dao('some name'); } public function initiateInserts() { while (($data=fgetcsv($this->fin,5000,";"))!==FALSE) { $initiate_inserts = $this->dao->initiateInserts($data); } } public function initiateCUpdates() { while (($data=fgetcsv($this->fin,5000,";"))!==FALSE) { $initiate_updates = $this->dao->initiateCUpdates($data); } } public function initiateExecuteIUpdates() { while (($data=fgetcsv($this->fin,5000,";"))!==FALSE) { $initiate_updates = $this->dao->initiateIUpdates($data); } } } catch (Exception $e) { } }

  • Correct syntax for php inside a feed request

    - by Simon Hume
    Hi guys, I have a very basic query string which passes a ID to a receiving page. On that page, I need to dynamically call the YouTube API, giving my playlistID. I'm having to use PHP for this, and it's a little out of my comfort zone, so hopefully someone can wade in with a quick fix for me. Here is my variable $playlist; And I need to replace the 77DC230FBBCE4D58 below with that variable. $feedURL = 'http://gdata.youtube.com/feeds/api/playlists/77DC230FBBCE4D58?v=2'; Any help, as always, greatly appreciated!

  • Why would you use "AS" when aliasing a SQL table?

    - by froadie
    I just came across a SQL statement that uses AS to alias tables, like this: SELECT all, my, stuff FROM someTableName AS a INNER JOIN someOtherTableName AS b ON a.id = b.id What I'm used to seeing is: SELECT all, my, stuff FROM someTableName a INNER JOIN someOtherTableName b ON a.id = b.id I'm assuming there's no difference and it's just syntactic sugar, but which of these is more prevalent/wide-spread? Is there any reason to prefer one over the other?

  • SQLiteException and SQLite error near "(": syntax error with Subsonic ActiveRecord

    - by nvuono
    I ran into an interesting error with the following LiNQ query using LiNQPad and when using Subsonic 3.0.x w/ActiveRecord within my project and wanted to share the error and resolution for anyone else who runs into it. The linq statement below is meant to group entries in the tblSystemsValues collection into their appropriate system and then extract the system with the highest ID. from ksf in KeySafetyFunction where ksf.Unit == 2 && ksf.Condition_ID == 1 join sys in tblSystems on ksf.ID equals sys.KeySafetyFunction join xval in (from t in tblSystemsValues group t by t.tblSystems_ID into groupedT select new { sysId = groupedT.Key, MaxID = groupedT.Max(g=>g.ID), MaxText = groupedT.First(gt2 => gt2.ID == groupedT.Max(g=>g.ID)).TextValue, MaxChecked = groupedT.First(gt2 => gt2.ID == groupedT.Max(g=>g.ID)).Checked }) on sys.ID equals xval.sysId select new {KSFDesc=ksf.Description, sys.Description, xval.MaxText, xval.MaxChecked} On its own, the subquery for grouping into groupedT works perfectly and the query to match up KeySafetyFunctions with their System in tblSystems also works perfectly on its own. However, when trying to run the completed query in linqpad or within my project I kept running into a SQLiteException SQLite Error Near "(" First I tried splitting the queries up within my project because I knew that I could just run a foreach loop over the results if necessary. However, I continued to receive the same exception! I eventually separated the query into three separate parts before I realized that it was the lazy execution of the queries that was killing me. It then became clear that adding the .ToList() specifier after the myProtectedSystem query below was the key to avoiding the lazy execution after combining and optimizing the query and being able to get my results despite the problems I encountered with the SQLite driver. // determine the max Text/Checked values for each system in tblSystemsValue var myProtectedValue = from t in tblSystemsValue.All() group t by t.tblSystems_ID into groupedT select new { sysId = groupedT.Key, MaxID = groupedT.Max(g => g.ID), MaxText = groupedT.First(gt2 => gt2.ID ==groupedT.Max(g => g.ID)).TextValue, MaxChecked = groupedT.First(gt2 => gt2.ID ==groupedT.Max(g => g.ID)).Checked}; // get the system description information and filter by Unit/Condition ID var myProtectedSystem = (from ksf in KeySafetyFunction.All() where ksf.Unit == 2 && ksf.Condition_ID == 1 join sys in tblSystem.All() on ksf.ID equals sys.KeySafetyFunction select new {KSFDesc = ksf.Description, sys.Description, sys.ID}).ToList(); // finally join everything together AFTER forcing execution with .ToList() var joined = from protectedSys in myProtectedSystem join protectedVal in myProtectedValue on protectedSys.ID equals protectedVal.sysId select new {protectedSys.KSFDesc, protectedSys.Description, protectedVal.MaxChecked, protectedVal.MaxText}; // print the gratifying debug results foreach(var protectedItem in joined) { System.Diagnostics.Debug.WriteLine(protectedItem.Description + ", " + protectedItem.KSFDesc + ", " + protectedItem.MaxText + ", " + protectedItem.MaxChecked); }

  • What does the >> symbol mean in Haskell.

    - by CharlesS
    I was reading the Guestbook example for Happstack and noticed the symbol which I didn't see before in the textbooks I studied to learn Haskell (for instance see line 23). What is it? Example I could not find it in Google because it ignores the totally (Bing does not but comes up with tons of non-related results). Thanks!

  • Why doesn't ADL find function templates?

    - by Huw Giddens
    What part of the C++ specification restricts argument dependent lookup from finding function templates in the set of associated namespaces? In other words, why won't the following compile? namespace ns { struct foo {}; template<int i> void frob(foo const&) {} } int main() { ns::foo f; frob<0>(f); }

  • invalid argument IE7 javascript line number changes

    - by Lauren
    This is the test page: http://www.onebagoneearth.com/ OBOEKindBag (spaces between the pagename and domain because I don't want the URL indexed as such) If you click on one of the thumbnails, or on the main image, you see a popup window, and if you enter a quantity and then click "add to cart" here, in IE7 (and IE6, but I'm not focusing on that as much), you see an invalid argument error with Code:0. The line # changes depending on which item you add to cart! The URL also changes because it depends on this line of javascript: var cartUrl = "/app/site/backend/additemtocart.nl?c=659197&n=2&buyid=" + zbuyid + "&qty=" + zqty + "&" + strOptionId + "=" + zitmId . The strOptionId variable, which contains the bag color type (ie. this changes for the different types of bags, like Kind bags, regular OBOE bags), and the zitmID variable which contains the particular bag color that you've selected (ie. Black), are what change, and also what seem to affect the line number that the invalid argument occurs on. The error definitely doesn't occur in Chrome 4, IE 8, or FF 3.5. Ideas?

  • asynchronous .js file loading syntax

    - by taber
    Hi, I noticed that there seems to be a couple of slightly different syntaxes for loading js files asynchronously, and I was wondering if there's any difference between the two, or if they both pretty much function the same. I'm guessing they work the same, but just wanted to make sure one method isn't better than the other for some reason. :) Method One (function() { var d=document, h=d.getElementsByTagName('head')[0], s=d.createElement('script'); s.type='text/javascript'; s.src='/js/myfile.js'; h.appendChild(s); })(); /* note ending parenthesis and curly brace */ Method Two (Saw this in Facebook's code) (function() { var d=document, h=d.getElementsByTagName('head')[0], s=d.createElement('script'); s.type='text/javascript'; s.async=true; s.src='/js/myfile.js'; h.appendChild(s); }()); /* note ending parenthesis and curly brace */

  • Netbeans Editor Library?

    - by Jeremybub
    Netbeans seems to say in several places that it supports a library to just host the "Netbeans editor" widget in some other program. It has some weird documentation that seems to say a lot, but doesn't really say much about how to use it: http://bits.netbeans.org/dev/javadoc/org-netbeans-modules-editor-lib2/architecture-summary.html I can't seem to find any download for the "Netbeans editor library" (1 or 2), and the documentation they provide says to download the entire mercurial repository, which doesn't really help me, since it doesn't tell me what is part of this "library" and what is not. If someone could point me to a download for this library, or some minimal documentation about how to use it, that would be great. I've already seen the blog post here, but it doesn't really help with getting the library, and it seems to be talking about classes which I can't find in the Netbeans sources I downloaded (Maybe a different version?)

  • Syntax to change the value of a cached object property

    - by Craig
    In an ASP.NET 3.5 VB web app, I successfully manage to cache an object containing several personal details such as name, address, etc. One of the items is CreditNum which I'd like to change in the cache on the fly. Is there a way to access this directly in the cache or do I have to destroy and rebuild the whole object just to change the value of objMemberDetails.CreditNum? The cache is set using: Public Shared Sub CacheSet(ByVal key As String, ByVal value As Object) Dim userID As String = HttpContext.Current.User.Identity.Name HttpContext.Current.Cache(key & "_" & userID) = value End Sub
