Use the profiler to see what is still referencing them.
Thanks for you interest...
sorry..I really don't know what is profiler...
This is my scenario..
I have one custom control (named as CUSTOM) extends canvas. in that i have textinput and combobox. it has property ID.
CUSTOM listens parentApplication for OPEN event. if OPEN event triggered from parent. CUSTOM checks it's property ID. if it's property ID is matched it opens it's combobox.
i added 300 CUSTOMs in VBox. Each has separate ID. in certain case i remove this 300 CUSTOM from my VBOX using removeAllChildren() function.
After that i dispatched OPEN event. I thought 300 CUSTOMs are removed. But from somewhere CUSTOM catched that event and opens it combobox.
so it is still in UI. i never want that 300 CUSTOM in my app
As per the post,
I think i should remove event listeners of the CUSTOM component which listens parentApplication. After that i will check with profiler
using this post.
