[jboss-jira] [JBoss JIRA] (DROOLS-247) Property reactivity does not work with positional/unification constraints

[RH Bugzilla Integration (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-247?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12823815#comment-12823815 ] 

RH Bugzilla Integration commented on DROOLS-247:
------------------------------------------------

Mario Fusco <mfusco at redhat.com> made a comment on [bug 1021803|https://bugzilla.redhat.com/show_bug.cgi?id=1021803]

Positional and/or unification constraints are interpreted as either bindings
or constraints, depending on the whether the variable is already bound or not. The user is expected not to have to care about the difference.

...
Person( $name; $age := age )
...

If the pattern type is @propertyReactive, however, the actual decision
between binding and constraint WILL make a difference, possibly forcing
the user to use @watch()
