Hi Manish My listItemRenderer is an MXML component that dervies from VBox. It doesn't have a listData attribute.
I looked up listData renderer and found that components that wish to be a drop-in renderer should implement the IDropInListItemRenderer interface. I take this to mean that my VBox-based list item renderer should implement this interface, but I don't know how to accomplish this. If my component were an AS file, it would be simple. But how can an MXML component implement an interface? I tried adding "get listData" and "set listData" functions, hoping that they would be discovered at runtime. It would seem that they are, since "get listData" is being called frequently, but "set listData" is never called. Any advice? Thanks.
