Override the combobox class in a custom component and add the following code
-
private var mDropDown:ListBase;
override public function set dataProvider(value:Object):
void
{
super.dataProvider = value;
//Bug in Flex SDK 3.5: Once the data provider is set and list base is
created
//change in dataProvider does not reflect change in shared dataProvider
of listbase
mDropDown = dropdown;
if(mDropDown)
{
validateSize(true);
mDropDown.dataProvider = super.dataProvider;
if(isNaN(preferredDropDownWidth))
mDropDown.width = width;
else
mDropDown.width = preferredDropDownWidth;
}
}
The problem is also solved in 3.6 sdk .
