New children got discovered for the JBossAS Server resource I was currently viewing in the GUI. When I went to the Inventory>Children subtab, the ne children were listed. However, they never appeared in the resource tree. I had to go to a different page in the GUI and then return to the resource in order for nodes to show up in the tree for the new child resources.
this illustrates a general problem with the left hand tree - it is maintained/refreshed independently of what is happening on the server. For example, if you uninventory or manually add children, the tree doesn't refresh when the children list changes
