             Summary: Allow both prefixed and infixed AND in nested accumulates 
                 Key: DROOLS-3499
                 URL: https://issues.jboss.org/browse/DROOLS-3499
             Project: Drools
          Issue Type: Feature Request
          Components: core engine
            Reporter: Mario Fusco
            Assignee: Mario Fusco


At the moment drools can compile composite condition in a nested accumulate only using a prefixed 'and' like in

{code}
    String($l: length)
    accumulate(
        (and
            Integer(this == $l) 
            accumulate(
                Long() 
                ;$counter: count(1);$counter <= 4)
         )
        ;$mainCounter: count(1);$mCounter <= 2
    )
{code}

while it fails when using the infixed notation like in:

{code}
    String($l: length)
    accumulate(
        (
            Integer(this == $l)  and
            accumulate(
                Long() 
                ;$counter: count(1);$counter <= 4)
         )
        ;$mainCounter: count(1);$mCounter <= 2
    )
{code}

It is required that this could work also with the infix AND also because this is notation used by the DRLDumper when regenerating the drl from a PackageDescr
