Is .clear() no longer supported? [message #884142]

I've just downloaded the current version of Zest. One of the JAR files is called org.eclipse.zest.core_1.3.0.v20110221-2050.jar. So, my code uses a clear() method for clearing all the elements in a graph, like this:

wbsGraph = new Graph(this,SWT.NONE);
...
wbsGraph.clear();

But this doesn't work anymore. Was this method removed from the current version? Is there another way of doing this?

I don't think this was ever supported in Zest 1.x - I remember adding it to Zest 2.x though:

http://git.eclipse.org/c/gef/org.eclipse.zest.git/commit/?id=3a37e2f51dc355a30642682defd99d14111cc9f7

It should work with the latest version of Zest 2, which is available from the Eclipse Marketplace.

Okay, well that wasn't there. I got the sources and added that function (to Graph.java), and that seemed to work. However, I don't know what subGraphFigures are, but that part wasn't working so I just commented it out:

public void clear() {
	for (Iterator i = new ArrayList(connections).iterator(); i.hasNext();) {
		removeConnection((GraphConnection) i.next());
	}
	//for (Iterator i = new HashSet(subgraphFigures).iterator(); i.hasNext();) {
		//removeSubgraphFigure((IFigure) i.next());
	//}
	for (Iterator i = new ArrayList(nodes).iterator(); i.hasNext();) {
		removeNode((GraphNode) i.next());
	}
}

Anyway, thanks for the help!
