A DESCRIPTION OF THE PROBLEM :
in a JList with multiple column layout, the horizontal navigation keys are not updated of the ComponentOrientation is changed at runtime. This happens in a LToR default context (mine) if the LAF is Nimbus:

- create and show an arbitrary frame with a list configured to show multiple columns with some control to change the ComponentOrientation
- navigate horizontally: RIGHT arrow key moves selection the right, that is to the NEXT element in the row, LEFT to the left which is the PREVIOUS element
- toggle CO to RToL
- navigate horizontally: RIGHT arrow key still moves to the NEXT which now is left and LEFT still moves to the PREVIOUS which now is right

all other LAFs keep the direction and remap the semantics: that is in RToL they have RIGHT == PREVIOUS and LEFT == NEXT

(description is more complicated than the problem <g>)

Same for JTable

Don't know if it's regression, maybe never worked for Nimbus, but mark it as such as it's working as expected in the other LAFs. Might be a show-stopper in multi-language contexts which need to toggle CO.

Cheers
