Clearing input-map of a JSplitPane

Question

I chased down some keyboard problems to JSplitPane eating my cursor keys for WHEN_ANCESTOR_OF_FOCUSED_COMPONENT. I saw those entries in the step debugger. But when is the input map actually populated? Because if I try to clear it, there is nothing there...

val sp = new javax.swing.JSplitPane(orient, left, right)
val map = sp.getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT)
map.clear()

Then that map is already empty. So it must be filled at a later point?

Answer 1

While it doesn't directly answer my question, it solves my problem:

UIManager.getDefaults.remove("SplitPane.ancestorInputMap")
