[jboss-jira] [JBoss JIRA] Commented: (JBRULES-1759) Exception when compiling a rule with "dialect mvel"

[Ming Jin (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBRULES-1759?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12428246#action_12428246 ] 

Ming Jin commented on JBRULES-1759:
-----------------------------------

Mark,
Thanks for the information.  The rule compiled after removing the new array constructor.  But it generated a run time exception because MVEL parsed the array as array of Object's, an array of String[]'s:

Caused by: org.mvel.PropertyAccessException: unable to resolve property: unable to resolve method: test.TestObject.stayHasDaysOfWeek(java.lang.String, java.lang.Boolean, [Ljava.lang.Object;) [arglength=3]
	at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.getMethod(ReflectiveAccessorOptimizer.java:604)
	at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.compileGetChain(ReflectiveAccessorOptimizer.java:272)

Any work around except change the method definition?

> The following expression would compile without any problem with "dialect java":
> new String[][]{{"2008-04-01", "2008-04-10"}}
> But would generate a compiler error - "Unable to build expression...." with "dialect mvel".
> Will upload an sample code to demonstrate this bug.
