Subject Re: Indirect property lookup failing.
Date Mon, 30 Apr 2007 16:37:06 GMT

yes properties are by design immutable (once set cannot change)
I think you may want to look at implementing dynamic set capability with 
'variable'
http://ant-contrib.sourceforge.net/tasks/tasks/variable_task.html

Does this help?
