Problems with GVTTreeAdapter

["Bishop, Michael W. CONTR J9C880" <Mi...@je.jfcom.mil>]

In a whiteboard, I'm switching pages (documents) and refreshing pages
for images, etc., causing me to wait for the GVTTree to render and I
believe it's causing errors in my application.  At random times, I get
an NPE when trying to access the UpdateManager.  If I already have an
"onLoad" listener attached to the document, can I just use that class to
tell me when everything's ready?  Doesn't "onLoad" come after the
GVTTree and ensure that the UpdateManager is ready?

   From memory onLoad actually happens before the UpdateManager is 
started, this is because
we run onLoad before the first rendering happens.  You should wait for the 
first
gvtRendered callback before accessing the updateManager.
