cellbrowser open/close nodes programatically

I'm using the gwt cellbrowser, so far it has been an uphill battle. I
got this bad feeling that I'm not using it as it is intended to be
used.

It seems to me that:

there is a difference between selecting a node and opening that node.
there is no way to open/close nodes programatically.
the cellbrowser's open/close handlers never fire (although clicking on
a node renders that node's children in the next panel.
I'm able to use the selectionModel to select a node but that doesn't
open the node. In other words, the node's children don't show up
(until I click on the node).

Is there anyway, I can open and close nodes programatically?

Thanks in advance.
