I'm getting a runtime error when I attempt to expand a treeview node
TypeError: Error #1006: Call attempted on an object that is not a function.
at flex_treeview3a/::geticon()
I suspect it's the way I'm using item.hasOwnProperty() but I'm out of ideas.
the "geticon()" function is for the tree's iconFunction. In this I'm trying to
if the node is a leaf ("activity")
get the activity type, set leaf icon to activity Type icon
else if is root
set top branch node to root icon
else (must be branch)
set branch icon
can anyone see what I've got wrong?
thanx
