Re: Assembler: Not able to call the method createItem but able to call
the method getItem and fill from Flex application.


Hi,

I'm new to Flex and currently having some problem on calling/reaching
my Assembler class method createItem. I find it weird because I manage
to call/reach both fill and getItem method but just couldn't call the
createItem method reside in my Assembler class. Below is the details
of my code:

main.mxml (just part of the code...)
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
xmlns:component="*" layout="absolute" creationComplete="getSource()">
 <mx:DataService id="ds" destination="videoService"
result="setData(event)"/>
 <mx:DataService id="vcds" destination="commentsService"/>

private function getSource():void{
        ds.getItem({videoId:2});

}

private function setData(event:ResultEvent):void{
video = VideoItem(event.result);
         movie = "/videoshow/"+video.uploadPath+"/"+video.videoFileName;
videoDisplay.play();
   btnPlay.label = "Pause";
   IS_PAUSED = false;
}

private function submitNewComment():void{
var comment:VideoComment;
comment = new VideoComment();
comment.comments = StringUtil.trim(commentTextArea.text);
comment.videoId = video.videoId;
comment.userId = 1;
                //vcds.getItem({commentsId:1}); --> This part is
working fine
                var ref:ItemReference = vcds.createItem(comment);
//This part is not working
                vcds.commit();

}

My Assembler class

public class VideoCommentAssembler extends AbstractAssembler {

public void createItem(Object item) {
System.out.println("Inside createItem of VideoCommentAssembler.......");

VideoUploadService.getInstance().createVideoComment(
(VideoComments) item);

}

public void deleteItem(Object previousVersion) {
System.out.println("Here!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
super.deleteItem(previousVersion);
}

public Collection fill(List fillParameters) {
// TODO Auto-generated method stub
return super.fill(fillParameters);
}

public Object getItem(Map identity) {
System.out.println("inside getItem of VideoCommentAssembler.");
return VideoUploadService.getInstance().loadVideo(((Integer)
identity.get("commentsId")).intValue());
}

public void loadComments(String _string){
System.out.println("Inside Assembler loadComments method.");
}
}

Hopefully someone can really help me on this as I spend almost 3 days
to find out what is wrong with my code/setting. Just couldn't
understand why cant the createItem method in my Assembler class been
called (The system.out.println inside the createItem is not been
printed on my console), where else the other 2 method : fill and
getItem able been called successfully (The system.out.println inside
both this method can print out ...in my console).

Fyi, there's no error...nothing occur in my console, log, or the flex
client side (on my browser).
I going to be crazy soon!! Someone....please help!
