Hi , thanks Troy, I alredy checked what u advise, unfortunately it didnt work, i'd like to think this is a bug from Flex API cuz u dont thing im doing anything wrong.
The problem happens with any kind of renderers, custom renderers, inline renderers, im so frustrated, something like using and item renderer should be easy, or at least should work. Im still open to suggestions, if anyone knows the solution please tell me. thanks anyway.
