Hi All,<br>
<br>
As a first time GIT user... I think I have manager to "pull this off"<br>
and submitted a pull request for a test case in the drools-compiler<br>
project. This should add one file in src/test/ in the package<br>
org.drools.compiler.integration as I deemed that to be the most<br>
appropriate place.<br>
<br>
Regards,<br>
Willem<br>
