Has anyone else come across this when inserting a node into a Tree:
java.lang.UnsupportedOperationException
at java.util.AbstractList.add(AbstractList.java:151)
at
org.apache.wicket.markup.html.tree.AbstractTree.treeNodesInserted(AbstractTree.java:779)
at
javax.swing.tree.DefaultTreeModel.fireTreeNodesInserted(DefaultTreeModel.java:497)
at
javax.swing.tree.DefaultTreeModel.nodesWereInserted(DefaultTreeModel.java:294)
at
javax.swing.tree.DefaultTreeModel.insertNodeInto(DefaultTreeModel.java:223)
at
homeiq.wicket.building.tree.BuildingTreeModel.addRoom(BuildingTreeModel.java:79)
at
homeiq.wicket.building.tree.ModalNewRoom$1.onSubmit(ModalNewRoom.java:36)
I traced through and saw a Vector was being created but not sure why it
wouldn't support add( int, Object ).
Any ideas?
- Doug
