/**

	 * Regression for  Bug 317783 -  Resource filters do not work at all in "Project Explorer" 

	 * The problem is that a client calls explicitly refreshLocal on a folder that is filtered out by 

	 * resource filters and that doesn't exist in the workspace.  This used to cause the resource to

	 * appear in the workspace, along with all its children, in spite of active resource filters to the

	 * contrary.
