I had some troubles to re-load my itemrenderer. When the dataprovider of your collection (Tilebase or whatever) chage, the itemrenderer of exists items does not re-init, if your code is in creationComplete event. Finally I found a solution:in your itemrenderer file, on the creationComplete handler, add:
this.addEventListener(FlexEvent.DATA_CHANGE, dataChanged);dataChanged();
Then, in the dataChange function, you can do whatever you want for your itemrenderer when your dataprovider change.Hope this will help someone.
