[jboss-jira] [JBoss JIRA] Commented: (JBRULES-1284) ClassCastException when using "<" constraint on field of type java.lang.Object containing data of type java.lang.Integer
[ http://jira.jboss.com/jira/browse/JBRULES-1284?page=comments#action_12383376 ]
Michael Neale commented on JBRULES-1284:
----------------------------------------
OK - yes well at compile time it decides to coerce to a string, yet gets a rude shock at
runtime.
not much more we can do at compile time for this, but at runtime I will see if we can do a
better coercion.
ClassCastException when using "<" constraint on field of

Key: JBRULES-1284
URL: http://jira.jboss.com/jira/browse/JBRULES-1284
Project: JBoss Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: 4.0.2
Environment: Windows XP, Eclipse 3.2
Reporter: Justin Wick
Assigned To: Mark Proctor
Attachments: DroolsTest.zip
If I'm doing a pattern constraint, say "< 50" on a field, and that field
is type java.lang.Object, with a value of type java.lang.Integer, a ClassCastException is
generated at run time, although there is no compile-time error saying that this is an
illegal constraint.
