New Revision: 1331802

URL: http://svn.apache.org/viewvc?rev=1331802&view=rev
Log:
Overhauled Mini-language <check-errors> and <add-error> elements.

This commit fixes a bug in the <add-error> element. Some of the tests written in Mini-language fail now because errors were previously ignored, but now the error handling works properly.

To assist the developer community with fixing the tests, I added an INFO log message to track down the faulty test code. Run the tests, and then search the log file for "<add-error>".
