If you have a server not set to auto synch (i.e. refresh time 0), or which is not readable by anonymous, the instance node will show [Disconnected] or [Forbidden]. To connect, you need to go to the context menu and select Connect (or Log In). That is fine but it would be more convenient to merely expand the node, since your expectation is that expanding the children of a node showing the contents of the server should go ahead and try to connect to it.
Probably risky for 7.3 so marking for the next release.

Log: #224587: connect as needed when instance node expanded.
Also removing gratuitous old calls to Node.setChildren;
the Children field should normally be considered final.
