SUGGESTED FIX Fix Basic LAF where it gets UIManager keys to use defaults any where it causes exceptions.
29-05-2008
EVALUATION I think we need to do a more thorough look at using Basic LAF UI delegates with Nimbus as this is the 4th or 5th bug from this. Although there is no requirement for this to work it happens to work on all the other Sun LAFs so people expect it to work with Nimbus. Attached is a test class that tests all components with BasicUI delegates and causes many expetions before this fix. I also tested with the DbVisualizer application and JIDESoft demo suite to see if they caused any exceptions. I tested with JIDESoft demos because the component in DbVisualizer that was causeing the exception is one of the JIDE Component suite. So hopefully this will be the last bug related to issues mixing Basic UI delegates with Nimbus LAF.

EVALUATION Looks like some more missing UIManager keys needed by basic laf.
