RE: Basic Tiles question!

Posted by Michael McGrady <mi...@michaelmcgrady.com>.
And, more "Hmm...", it looks like whatever is assumed to have a value other 
than null at line 528 of InsertTag.java, so that you can look at the source 
code to see what that might be.  My guess is that there is some "name" 
object that is being passed into that "processName" method that is null.
