Hi there
I have an ArrayCollection value in my model class, which I would like
to run through a formatter function in my view. This method works with
a string, but performs strangely for a collection, where:
1) The format function is never called on update
2) The bound control reflects the update if I return the
ArrayCollection reference from the function, and doesn't reflect the
update if I return a reference to a different object (even though the
function is never called)
View:
-------------------- snip ---------------------------
// formatting function
public function formatTree(data:ArrayCollection) {
data.addItem(new MoveVO());
return data;
}
-------------------- /snip ---------------------------
-------------------- snip ---------------------------
// tree control
<mx:Tree id="moveTree" x="203" y="2"
dataProvider="{formatTree(model.currentMoves)}" labelField="text"
height="190" width="193"></mx:Tree>
-------------------- /snip ---------------------------
I have also tried using a <mx:Binding> tag to perform the operation,
as well as Paul Williams 'smallest tag'*, both of which do not reflect
an update to the ArrayCollection value. Trying to follow up on this in
the documentation I found the following, which seems to imply that the
formatting function should work:
"You can use ActionScript functions as the source of binding
expressions. You usually do this when using a bindable property as an
argument of a function. When the bindable property changes, the
function executes, and the result is used in the binding destination ..."
Regards
Tracy
