TreeView can't display nodes with "<" character

Taking a working treeML file and changing an attribute value to contain "<" causes the following error:

Dec 15, 2012 7:50:23 PM prefuse.action.ActionList run

java.lang.IllegalArgumentException: Invalid row index: -1

I did some searching around and this appears to be illegal in XML, but using the XML replacement "&#60;" doesn't seem to work, here.

Try to replace "<" with "⁢".

The same error is produced using "⁢"
:(

I think some of the source of this error is that in the TreeML file provided (maybe in TreeML generally?) you have to specify node values as a value field in the attribute tag; everywhere I looked for XML said "just don't" use those special characters in attribute fields. If it were between an open and close tag, it might work, but I haven't figured out how to get the TreeML reader to read trees written like that.

That should be "&lt" not "&it"...give that a try?

Thanks, that worked! Sorry for it not being a real bug, although I guess that's good, too. x_x
