B4J Question [Solved] Accordion SelectedIndex

Does it work properly if you add it with LoadLayout?

Yes.

LoadLayout is the recommended way. The designer takes care of handling the resize events. This will be complicated to do properly in your code.

Anyway, you can create a layout with a Pane anchored to all sides, load it and then add the nodes you like to the pane.

That doesn't work either. The problem seems to be coming from the fact that I'm adding an accordion to each row of a listview. I'm doing that in order to get the opening/closing of the internal accordions to expand and contract properly without overrunning what's below

Here's the basics ...

Listview row
Accordion-Parent
textfield
textfield
accordion-Child

Listview row
Accordion-Parent
textfield
textfield
accordion-Child

etc...

The Child accordions are initially closed. The Parent accordions are initially open. The Child accordions are created via Loadlayout.

Never mind. I found the mistake. I was adding the TitledPanes to the listview instead of the entire Accordion. It works correctly now.
