Re: TopComponent/setActivatedNodes not workin with a given layer.xml file.

Well... if you want to synchronize with the Properties window, you must 
have properties, right? And if you're not publishing your properties, 
yes, indeed, the Properties window will not see them.

Looks like you're doing something a bit suboptimal somewhere, i.e., it's 
unlikely that you actually need setActivatedNodes at all.

You need to basically publish that Node into the global Lookup. 
'setActivatedNodes' is a really old way to do so. Doesn't look like 
you're making use of an ExplorerManager, so I suggest you use 
Utilities.actionsGlobalContext instead.

Here's a tutorial for you:
