Hi Walter,
I understand it’s not supported, but it does seem to be working, and it’s very useful. It’s related to the click event we discussed in the other thread – I use a go.Binding("name","whatever") on an itemArray and then a node.findObject(whatever) to toggle the visible property of the element in question. It’s effectively a solution to parametrising the target of the panel expander buttons. If you can suggest a more elegant/framework-aligned way of doing it, that would be great, but for the problem in this thread it’s an aside.
Best
F
