UITree method not implemented --

[brian13]

Hello,
The following UITree method in 3.3.0
does not have an implementation and throws an Unsupported Operation exception.
The 3.3.1 release notes do not indicate that this method had been implemented.

public void updateSelectedNode( UITree tree) {
TreeNode selectedNode;
Object key = tree.getTreeNodeRowKey(selectedNode);
TreeRowKey newCurrentRowKey = (TreeRowKey) key;
tree.setRowKey(newCurrentRowKey);
}

The method "getTreeNodeRowKey" lacks an implementation for sure ... not sure about the
method "setRowKey" as it is not reached with the thrown exception.

Are there any plans or can we request an implementation of these methods in the UITree API in the next GA release ? In the meantime is there a work-around to achieve the above with implemented methods ...

Thanking you in advance,
-- Brian

Hi Brian,

You are probably using data model that doesn't support such operation. What is type of used tree nodes?

Hi Nick,

I have a separate datamodel for the tree nodes that implements the interface TreeNode and another interface from our system ... the method seems to accept instances of this tree nodes when compiled. ... but the error comes from the instance of the UITree that I am
calling the method on .... the instances of the UITree I do not create but are generated from the rich:tree adviseNodeOpened parameter method binding.

This type of data model does not work with TreeNode objects, that's why the exception is thrown.
