Problem with tree upgrading from 3.2.1.GA to 3.3.1.GA

[shipmaster]

Hi everyone,

I have a changeExpandListener as follows:

@SuppressWarnings("unchecked")
 public void changeExpandListener(NodeExpandedEvent evt) {

 TreeState state = (TreeState) ((UITree) evt.getComponent())
 .getComponentState();
 NST node = (NST) ((UITree) evt.getComponent()).getRowData();
 TreeRowKey key = (TreeRowKey) ((UITree) evt.getComponent()).getRowKey();
 log.debug("Row key is {}", key);
 if (state.isExpanded(key)) {
 log.debug("Adding node to expanded");
 if (!expandedNodes.contains(node))
 expandedNodes.add(node);
 } else {
 log.debug("removing node from expanded");
 expandedNodes.remove(node);
 }

 }

This was working in 3.2.1.GA, the log output for it was

11:08:16,306 INFO [STDOUT] 11:08:16.306 [http-127.0.0.1-8080-4] DEBUG c.o.t.NestedSetTreeEditorController - Row key is j__id4:0:j__id4:0
11:08:16,307 INFO [STDOUT] 11:08:16.307 [http-127.0.0.1-8080-4] DEBUG c.o.t.NestedSetTreeEditorController - removing node from expanded

When I upgraded to 3.3.1.GA, the output became

11:13:05,717 INFO [STDOUT] 11:13:05.717 [http-127.0.0.1-8080-4] DEBUG c.o.t.NestedSetTreeEditorController - Row key is j__id4:0:j__id4:0
11:13:05,717 INFO [STDOUT] 11:13:05.717 [http-127.0.0.1-8080-4] DEBUG c.o.t.NestedSetTreeEditorController - Adding node to expanded

So TreeState.isExpanded(key) always returns true for me now, is there a workaround or a different way I should be detecting node state?

Thanks.

Hi,

Try this:

((UITree) evt.getComponent()).isExpanded()

Hello,

Thanks for your reply,

That didn't work, and when I looked inside the UITree code, I found this:

public boolean isExpanded() {
 TreeState treeState = (TreeState) getComponentState();
 return treeState.isExpanded((TreeRowKey) this.getRowKey());
}

Which is identical to what I was doing?

Yes, I've filed this as: https://jira.jboss.org/jira/browse/RF-7273
