[flexcoders] Re: databinding back to source?
This is a known binding issue with B3. For now, you can refresh the
tree with:
tree.invalidateList();

Re: [flexcoders] Re: databinding back to source?
Thank you for the reply!
Sorry, I wasnt sure of the exact question because I wasnt sure what I
was looking for. So yes the data does update, but the visual
component itself does not.
For example, if you expand the tree, and edit "controls", when you
click on "controls" in the list view, the textinput and selectedItem
reference contain my changes, but the listview itself doesn't. Also
when editing the selected item, the debug text fields update as you
type.
I'm unsure of what you meant by a change notification structure like
binding. The datasources for both components are a plain object, and
I thought I was binding via the curly brackets on the click event? Do
I need to create a function that after updating the data, it refreshes
the tree/list manually?
function update(){
tree.selectedItem.label=lbl.text;
tree.;
}

[flexcoders] Re: databinding back to source?
I'm not exactly sure what the question is, but it seems you're asking
if changes to data pulled from the Tree will be seen in the
original data structure?
If that's what you mean, then you don't need binding, the Tree control
already uses (and returns) your data by reference. If you get a data
point from the Tree control (like selectedItem), then changes to that
reference will be reflected in your original data structure.
This doesn't mean that the changes will be seen by the Tree however.
Some data types, like Object, require a change notification structure
like binding or Collections.
Is that what you're looking for?
