Hi,
I've encountered a bizarre bug when a function is used together with a
declared type and a rule with mvel dialect.
To reproduce create a default 'New Drools Project' in Eclipse and replace
Sample.drl with the following:
--------------------------------------------------------------------------
package com.sample
function void aaa() { // <----- comment this and it will work
}
declare SomeBean
prop : int
end
rule "setup"
dialect "mvel" // <----- comment this and it will work
when
eval(true)
then
SomeBean someBean = new SomeBean();
insert(someBean);
System.out.println( "setup inserted:" + someBean);
end
rule "should never fire"
salience -20
when
not SomeBean()
then
System.out.println( "rule that should never fire fired !!!" );
end
------------------------------------------------------------------------
Run the DroolsTest.java and see that the last rule that should never fire is
actually fired. If you comment out the 'aaa' function or change the dialect
to 'java' all works fine.
Note that it breaks on JDK 1.5.0_12 however it works fine on JDK 1.6.0_14.
Tested on WinXP.
Is it just my machine or does anybody else see this issue?
Best regards,
Michal

Hi Michal,

I have been completely unable to declare a function within my .drl file
using mvel dialect as well..so I'm very interested in this.
Thanks,
Chris

Hi Edson,
Thanks for fixing this. I'll try it as soon as the SNAPSHOT build becomes
available in hudson. Also thanks for the detailed info in the JIRA.
