ListBase/List recycles renderers, but the renderers themselves have to be written in a way that supports recycling. Renderers must be completely data-driven, which means that aspects like their height must be determined from the data or related information. It looks like you're just storing a new height, so if a renderer set to 60 gets recycled as a renderer that should be 30, no code except a click will set it back to 30, which isn't right.

Here's an example, in a renderer a button resize itself on click: <mx:Button height="30" id="myButton" click="myButton.height = ( myButton.height == 30 ) ? 60 : 30" /> well if the user click the button, that's not the one clicked that will be resized but another one in another random item renderer. The funny thing is that it happens only if: List variableRowHeight is set to true set data is overrid in the item renderer also that happen only on height change. My problem is that i need to show/hide the controls of my item editors on mouse over, i'll post some demo code later.
