PopUpMenuButton forwards event from it's internal Menu object. Menu only dispatches an itemClick event when the user clicks on a leaf node. You can monkey patch Menu to fire off events when an internal node is clicked by changing the mouseUpHander. By removing the check on isBranch from the line that reads
if (item != null && _dataDescriptor.isEnabled(item) && !_dataDescriptor.isBranch(item)) the Menu will behave as you expect it to (I'm using the version of the SDK that shipped with Flex Builder 3 -- if you have another build things might be different). You can then use the properties of the event to do whatever processing you needed. --- In [email protected], "sudha_bsb" <[EMAIL PROTECTED]> wrote: > > Hi, > > I am having strange problem with PopupMenuButton.
