Data Binding Issues in Flex 1.5   Well, your post made a little more sense after reading your article!  :)  It sure does go in depth, but it's definitely an interesting read.    http://www.macromedia.com/devnet/flex/articles/link_load_print.html   Thanks a bunch Roger...    ~thumbs up~   -Ben   On 12/7/05, Roger Gonzalez <[EMAIL PROTECTED]> wrote: In 1.5, we tracked the dependencies of static initializers for inclusion in the SWF, but because the statics are actually initialized while the movie is streaming in, we would also have needed to have tracked things to ensure that all classes referenced in the dependency tree of the right hand side of the static initializer are all earlier in the stream.  This was an overconstrained problem with few useful solutions.  What I added as a workaround was to at least track the LHS of static initializers for ordering.  This lets you resolve stuff with a bit of manual pain.  I wrote a devnet article that goes into more detail, if you feel like digging it up.   The solution for 2.0 was to reduce the need for strict ordering for statics by not initializing stuff until the end of the frame.  This way we just have the requirement that your references must be on the same frame (or earlier), but don't need to have strict ordering within the frame.  Much more solvable!   -Roger Roger Gonzalez [EMAIL PROTECTED]     From: flexcoders@yahoogroups.com [mailto: flexcoders@yahoogroups.com] On Behalf Of Ben Lucyk Sent: Wednesday, December 07, 2005 2:15 PM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Variable Initialization Bug? Data Binding Issues in Flex 1.5   Thanks for the tip Matt.    Do you have any more details (or a good reference to point me towards) as to why this is the case though?  There doesn't seem to be any problem initializing an instance variable this way at the "component" level.  Has this behavior changed at all in Flex 2.0 that you know of?    Ben   On 12/6/05, Matt Chotin <[EMAIL PROTECTED] > wrote: Instance variable assignment in the declaration is always dangerous because dependencies are generally not tracked for initialization purposes.  Assigning the variable in a function that's called later (like creationComplete or even initialize) is considered the best-practice.   Matt   From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Ben Lucyk Sent: Tuesday, December 06, 2005 1:03 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Variable Initialization Bug? Data Binding Issues in Flex 1.5   OK, help me out here, 'cause I've been scratchin' my head a little too hard on this one...   What I'm trying to do is setup a simple static class to use as a pointer to my main, global model, from within my MXML components.  I've been running into some "interesting" behavior that I can't explain, and I'm wondering if anyone can help shed some light.   (Couldn't find much help in the docs or forums)   I'm seeing that when I'm at the <mx:Application> level and I try to bind to a "global" variable that is initialized from the static class I mentioned above, no binding takes place unless I initialize the var after creationComplete().  This is NOT required however, when I'm trying to use the same type of binding in a component.  (The var seems to initialize fine)   I should mention that I've also tested this using a "normal" class ( var resource:String = new com.StaticResource().test;), and also a singleton class ( var resource = com.StaticResource.getInstance().test;).  No difference.   Any thoughts?     <<<< Sample Code >>>>   <!-------------------- StaticResource.as -----------------------> class com.StaticResource {     public static var test:String = "Bliggidy!"; }     <!------------------------------------------------------------------------>       <!-------------------- testStaticBinding.mxml  --------------->   <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx=" http://www.macromedia.com/2003/mxml"      creationComplete="doCreated()">      <mx:Script>      <![CDATA[       // Does not work here, only at "component" level!       //var resource:String = com.StaticResource.test;       var resource:String;          function doCreated() {            // Var must be set AFTER creationComplete in             // order to bind successfully!            resource = com.StaticResource.test;       }      ]]>      </mx:Script>      <mx:HBox>           <mx:Label text="Parent Level:" />           <mx:Label text="{resource}" />      </mx:HBox>      <components:testStaticBindingComponent xmlns:components="components.*" /> </mx:Application>   <!------------------------------------------------------------------------>     <!------ testStaticBindingComponent.mxml--------------->   <?xml version="1.0" encoding="utf-8"?> <mx:HBox xmlns:mx=" http://www.macromedia.com/2003/mxml">     <mx:Script>     <![CDATA[      // Does NOT need to wait for creationComplete() in order to       // bind successfully!      var componentResource:String = com.StaticResource.test;    //OK...        ]]>     </mx:Script>     <mx:Label text="Component Level:" />     <mx:Label text="{componentResource}" /> </mx:HBox>   <!------------------------------------------------------------------------>     Also, how are ModelLocators typically implemented using the Cairngorm framework?
