             Summary: Drools decision table with contains operator in a conditional group not working
                 Key: DROOLS-866
                 URL: https://issues.jboss.org/browse/DROOLS-866
             Project: Drools
          Issue Type: Bug
          Components: decision tables
    Affects Versions: 6.2.0.Final
         Environment: Windows 7
            Reporter: lucio piccoli
            Assignee: Mario Fusco


I cannot get the Decision Table to using grouping in the expression.

Decision Table
------------------------------------
<row 10> CONDITION
<row 12> classList $param

expressions are in each row.
<row 43> (contains('AAA') || contains('BBB') ) && contains('CCC') <--fails to compile
<row 44> (contains('AAA') || contains('BBB') 
<row 45> (contains('AA') || contains('BB') || contains('CCC') || contains('DDD')

where the fact classList is

List<String> classList = {'AAA', 'BB'.....}
the rule43 is meant to fire if the list contains either 'AAA' OR 'BBB' AND 'CCC'

however the decision table parser is failing with exception for rule 43

[Error: Missing left node]
[Near : {... classList (contains("AAA") || contains("CCC")) ....}]
i have a similar rule working fine for other rows

<row 42> contains('AAA') || contains('BBB') || contains('CCC')
there seems to be something strange with using the contains operator in a group condition.
