TreeTable: Filter CustomTreeNodes

Description Type of TreeNodes will be lost after filtering TreeTable. The problem is probably caused by

TreeTableRenderer.createNewNode(TreeNode node, TreeNode parent);

This method will always return DefaultTreeNode or CheckboxTreeNode, even if the Type of parameter node is CustomTreeNode. Because this method is called due filtering (TreeTableRenderer.filter(…)), the type of all nodes will be lost.

Environment:

• PF Version: 8.0
• JSF: Mojarra 2.3.9

Expected behavior createNewNode should return a node with the same type as node in parameter, so that nodes in TreeTable are the same type after filtering as before.

CustomTreeNode node = new CustomTreeNode(...);
TreeNode newNode = createNewNode(node, null) ;
if(newNode instanceof CustomTreeNode){
   //correct
}else{
   //incorrect
}

Possible solutions

• handle filtering without creating new nodes
• copy node via reflection

Yeah, but thats the current impl. A improvement for the future would be to add a “filtered” flag to the TreeNode and not render again based on this decision.

I see. Please test again - you need to set cloneOnFilter=true now
