setting TreeState in Wicket session?
I have a based web page which contains a wicket Tree, and need to keep the treestate for each extend webpages.
So I override the newTreeState( ) as below:
Tree cMenuTree = new Tree("menuTree", createTreeModel()) {
@Override
protected ITreeState newTreeState() {
ITreeState treeState = null;
WicketSession session = (WicketSession) MenuPanel.this
.getSession();
System.out.println("session.size:"
+ session.getSizeInBytes());
treeState = session.getTreeState();
if (treeState == null) {
treeState = new DefaultTreeState();
session.setTreeState(treeState);
}
return treeState;
}
But I find the size of WicketSession is increasing quickly while each webpage created.
I need to keep the treestate because of the template webpage.
Please teach me how to eliminate the session size to avoid StackOverflowError Exception.
Thanks.
Roland.
