[jboss-jira] [JBoss JIRA] (DROOLS-1245) Document limitation of (legacy) Accumulate CE Alternate Syntax: single function with return type

Document limitation of (legacy) Accumulate CE Alternate Syntax: single function with return type ------------------------------------------------------------------------------------------------ Key: DROOLS-1245 URL: https://issues.jboss.org/browse/DROOLS-1245 Project: Drools Issue Type: Enhancement Components: docs Affects Versions: 6.4.0.Final Reporter: Matteo Mortari Assignee: Matteo Mortari Fix For: 6.5.0.Final, 7.0.0.Final Document limitations and common pitfalls: h2. from+accumulate does not iterate This does NOT iterate over the elements of the accumulate function: {code:java} rule R when $theFrom : Object() from accumulate(MyPerson( $val : name ); collectList( $val ) ) then list.add($theFrom); end {code} and in fact the binded $theFrom : Object() is the List returned by the collect list. While normally the "from" iterates over the element of list/iterable collections. {code:java} rule R1 when $list : List( ) $s : Integer() from $list then out.add($s); end {code}
