For something like this you would want to update the progressBar in the set data override function. But remember to call super.invalidateDisplayList(); in that function to re-render. -TH CYNERGY

Are you updating the ProgressBar in the set data() override function? (or updateDisplayList, I am not sure when to use which.)

All the interaction with item renderer is expected to be done via data set to it. And the feedback may be for example bubbling event (though, I use this technique very seldom). When list-based control is created it creates as many item renderer instances as needed and only substitutes data afterwards. R.

I have an item renderer which is associated to the List. The items in the list contains lots of data, one of which is an indication of how many percent a task has been completed. My custom item renderer has a ProgressBar in it. Every 5 minutes, the data source for my list is updated, hence the progress bar should be updated. How can I detect the change in data source from the item renderer's class, so that I can change the progress bar status? I have always thought that new item renderer object is created everytime the list is updated (everytime the data source is updated, I cleared the array collection which is the source of the list and re add the new items). At the moment, my progress bar only looks right when the application first run. However, seems like the progress bar is updated randomly afterwards. Thanks. Ivan.
