[jboss-jira] [JBoss JIRA] (DROOLS-290) Can't parse condition as FieldConstraintDescr in 5.5.0

    [ https://issues.jboss.org/browse/DROOLS-290?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12811393#comment-12811393 ] 

Davide Sottara commented on DROOLS-290:
---------------------------------------

Constraints are handled differently in 5.5 as opposed to 5.0. In later versions, you can have "free-form" constraints as opposed to simpler <Field OP Value>.
This is not a bug. Are you manipulating the Descr tree yourself? Those classes have never been part of the public API, as far as I know

> hi everyone,
> I met a issue when I upgrade drools from 5.0.1 to 5.5.0. when I parse  a rule in the 5.5.0. It will parse condition as ExprConstraintDescr. However,It can parse this condition as  FieldConstraintDescr in the 5.0.1. I don't know that this is a bug or not. the rule is as following:
> rule "guy_13"
>     when
>         $g:Guy(age==13)
>     then
>         return true;
> end
> the root cause is the parser has parsed "$g:Guy(age==13)" as ExprConstraintDescr in the 5.5.0 and it can work in the 5.0.1.
