[cp-patches] FYI: BasicTreeUI.updateCurrentVisiblePath() only when treeModel != null

[Mark Wielaard]

Hi,

We didn't check whether or not we actually had a tree model set when we
updated the current visible path.

2005-10-30  Mark Wielaard  <address@hidden>

        * javax/swing/plaf/basic/BasicTreeUI.java
        (updateCurrentVisiblePath): Check whether treeModel is null.

This makes the Class Browser in the beanshell swing gui show up.
Unfortunately it doesn't seem to work yet. (Click on the Desktop, and up
pops a little menu where you can select "New Class Browser".)

Committed,

Mark
