Question

I have a code like this:

        <mx:Repeater id="allItemRepeator" 
                     dataProvider="{_model.allItems}"
                     >
                <components:ComponentSelector id="componentSelector"
                                              dataLoad="{allItemRepeator.currentItem}"  />  
        </mx:Repeater>

When code changes for allItems the item disapears from screen as expected but still sits in memory! I know this by a function inside a compoenent that has “trace” so the trace output still displays even after the component disappears from screen. How do I ensure that the element is deleted when it’s reference is deleted? Will using List-based component to display items instead of “Repeator” solve the problem (it requires significant refactoring of my code so I’m asking before trying it out)

Answer 1

Something is still holding onto a reference to the component, so it is not being garbage collected. Binding in particular (which I notice you are using) is notorious for this.

Best way to debug the problem is to run your application though the profiler and see what is keeping a reference to the component once it is removed.
