I'm working with the combo quite a bit just now. I have 2 windows.
First window contains a form panel as the windows only child.
Second window uses a card layout, and contains 2 panels; 1 grid (default view), and 1 form panel.
Each form contains an identically created combo.
If I click on the trigger on the first window, the list width is the same as the combo.
If I click the button on the second window that changes the active item to the form panel and then click on the combo trigger the list width is the width of the text (which in this case is tiny) and not the width of the combo.
What is happening here? Is this happening due to a delayed render of some kind?
If anyone can help point me in the right direction that would be appreciated.
