John Doe commented on JBRULES-1029:
-----------------------------------

I recently got chance to test this and foudn very strange issue after I update from svn trunk and built/installed things with maven:

org.drools.rule.InvalidRulePackage: Unable to build expression for 'from' node 'RuleHelper.search(content,"pattern","column")' : [Rule name=Verify_1, agendaGroup=MAIN, salience=0, no-loop=false]
Rule Compilation error : [Rule name=Verify_1, agendaGroup=MAIN, salience=0, no-loop=false]

the rule is exactly the same, could you please take a look at this?
