> 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.
