Hi All,
Thanks for the response.
1) I agree with the fact - that memory is not necessarily released just
after you remove the items from datagrid.
Now my question is how long I have to wait for GC to run and If they
are eligible for GC then memory should be coming down after I issue
Sytem.gc().
Why Memory usage is not coming down even after Force GC ???
1) I do not have any event listerner attached to dataGrid or
ArrayCollection, In fact, In my sample App , I just crated a data Grid
with data provider and thats it.
I suspect , dataGrid does not release its itemerenderer even after
removing all item
After digging the DG code I found following .
Why FreeItemRenderersTable is Strongly Referenced ??
public function DataGridBase()
{
super();
listType = "vertical";
defaultRowCount = 7; // default number of rows is 7
columnMap = {};
freeItemRenderersTable = new Dictionary(false);
}
Is this the only reason for itemrenderes not being eligible for GC ??
Please throw some light on it
Regards,
Dharmendra
