Description Torbjorn Norbye 2002-12-25 23:56:07 UTC

Occasionally, a rescan as a result of a document
edit causes a node the user has collapsed to
re-expand. I'm not sure why, since I've made sure
my code is not calling setSelectedNodes or
expandNode when this is occurring. I've noticed it
only happens with categories which have previously
been opened.

I inserted trace statements in the treetable code
too, but didn't get any hits, so next I need to
investigate JTree.

Comment 1 Torbjorn Norbye 2003-01-06 03:13:50 UTC

This looks like a problem in the TreeTable - it has the
following tree-model-listener which is responsible for
the call which expands the wrong nodes:

        protected TreeModelListener createTreeModelListener() {
            return new JTree.TreeModelHandler() {
                public void treeNodesRemoved(TreeModelEvent e) {
                    tree.setSelectionPath
(TreeView.findSiblingTreePath (e.getTreePath (), e.getChildIndices ()));
                }
            };
        }
