Lazy Tree get/setExpandedElements not Working [message #261346]

Hello!

I am using the new lazy tree feature from the org.eclipse.ui.example.jobs.

It works great, but I experience difficulties when trying to restore the
state of expanded nodes after a refresh.

public void refresh() {
Object[] expandedElements = this.viewer.getExpandedElements();
this.viewer.refresh();
this.viewer.setExpandedElements(expandedElements);
}

After the view.refresh() all nodes are collapsed and not in the original
expanded state. So the get/setExpandedElements method seems not to
work here.

Any help / workaround greatly appreciated.
