SVN externals

I'm trying to better understand how TC works with svn externals. I have the following SVN setup:

master
  trunk
    modules
       svn:externals to modules (these have -r on them)
module1
  trunk
module2
  trunk

The VCS Root set to master/trunk (with full external support). I have a VCS build trigger rule:

+:modules/module1/**/*

In my tests, I make a change to module1 and then update the external version in master/trunk/modules. From what I can gather, TC can correctly pick up changes to trunk/modules when the svn:externals property changes, but it doesn't know whether module1 or module2 changed. Am I understanding that correctly?

It also seems I cannot set checkout rules that traverse externals. So for example, a checkout rule like this,

+:modules/module1

does not work.


Using TC 6.0.2.
