Markus,
Yes, eval code block will pass through DRL compiler into the java
compiler. So you need to write the regexp as it is written in standard java
code.
Now, this must work:
Item( title matches "^Test\s*" )
Does not matter what characters title contains. If it is not working, it
is a bug. Can you please submit a JIRA with a test case showing the problem?
Thanks,
Edson
