Henri Biestro commented on JEXL-29:
-----------------------------------
The patch attached to JEXL-15 (2.0 trunk) should fix this too.

> URL: https://issues.apache.org/jira/browse/JEXL-29
> Project: Commons JEXL
> Issue Type: Improvement
> Affects Versions: 1.1
> Reporter: Weikuo Liaw
> Priority: Critical
> Fix For: 2.0
>
>
> This needs an enhanced JexlContext, as suggested in the prev request, to work.
> As configured validators in a validation form. It is nice for users to use
> those validators directly such as "required(object)" or "requiredif(object,
> not empty(object2))".
> I have added "LOOKAHEAD(3) Method() " in the Reference() in Parse.jjt, so it
> can be accepted but it needs changes to ASTMethod and JexlContext to work.
> void Reference() : {}
> {
> (LOOKAHEAD(Identifier() "[" ( Expression() | IntegerLiteral() |
> Reference()) "]") ArrayAccess() | LOOKAHEAD(3) Method() | Identifier() )
> (LOOKAHEAD(2) "."
