[rules-users] Test if String endsWith()

[Omar Baqueiro]

Follow up from my question. I have read more from the Drools expert
guide ( http://docs.jboss.org/drools/release/5.2.0.Final/drools-expert-docs/html_single
), and in Section 5.8.3.3.10.9 it talks about the str operator:

Message( routingValue str[endsWith] "R2" )


However, when I try to use the str operator I get an error:

no viable alternative at input 'str' in rule "Check the items of the
list and remove the ones that satisfy the condition" in pattern
OfferWrapper[19,26]: [ERR 102] Line 19:26 mismatched input '
"endsWith" ' expecting ']'

I tried both using endsWith with quotes and without quotes and I get a
similar error in both cases.

Mu rule is:
> import java.lang.String
rule "Check the items of the list and remove the ones that satisfy the
condition"
     lock-on-active
 when
     $wrapper : Wrapper(
                 id == "itemId",
                 email str[endsWith] "@email.com",
                 $items : list)
     $item    : Map() from $items
 then
     $items.remove($item)
 end


Any clue on why am I getting an error?
Thanks.
O.
