Strange behavior with the Tree component - RichFaces 3.0.1RC
Since I began to use RichFaces 3.0.1, I get a strange behavior with the Tree component.
I'm new with RichFaces, I don't know how to get out of this issue.
I am using Seam + RichFaces + Ajax4jsf + Facelets.
I'd simply like to add or remove a node from the tree by using a contextual menu.
With RichFaces 3.0.0 it (add + remove) worked well (by clicking on a button ).
But with RichFaces 3.0.1RC2, neither the button nor the context menu works.
Sometimes, it works by chance (I can't say why) but most of the time I get a java.lang.NullPointerException
at org.richfaces.renderkit.NodeRendererBase$TreeNodeOptions.(NodeRendererBase.java:47).
The code I use to delete or add a node is really simple.
public void removeChild( Object child )
{
TreeNode treeNode = getElements().remove( child );
if ( treeNode != null )
{
treeNode.setParent( null );
}
}
public TPZITreeNode findOrCreateNode( TPZResourceBean childResource, TPZITreeNode parent )
{
TPZITreeNode node = m_resourceCache.get( childResource );
if ( node == null )
{
node = createNode( childResource );
m_resourceCache.put( childResource, node );
parent.addElementNode( node );
}
return node;
}My tree page looks like this:
