Nested class, BRL and Java (error)

[TonyN]

Hi,

I have nested classes in the domain model and I imported these nested classes in order to use them in the guided editor.  Things are ok except when one of the rule required a custom java function, then I would get an error at 'build' package time (the error is 'not able to resolve TcItem$Dataset').   I think the compiler didn't like the '$' in the list of imported statements.  But if I don't import these nested classes, I won't be able to use them in the guided editor.  

I am new to Drools so I think there must be a way to be able to use nested class (w/ '$') and custom java functions together.

Please advise.

I am using Guvnor 5.2 final.

Thanks.

Hi,

This was a bug, but has been fixed for 5.4.0.Final.

The only workaround is to move the enumerations to their own class, rather than nest in another Class.

With kind regards,

To import a class B nested in class x.y.A, you'd use
   import x.y.A.B

(Actually, '$' is legal in Java names, so there must be another reason
for not being able to resolve a name.)

Hi,

I downloaded the Guvnor 5.4.0 CR1 and problem is still there (I am assuming the fix is in this CR release too?).  I would like to send this image to show one of class in the domain model that contains nested classes.  

TcItem contains Dataset contains NamedReferences



Thx

Nope, I meant 5.4.0.Final - as I typed :)

Can you create a JIRA (https://issues.jboss.org/browse/GUVNOR) and attach a repository export demonstrating the problem.

I can take a look to check it's working as you require with (what will become) 5.4.0.Final.

Otherwise, it'll be a bug and need fixing anyway.

With kind regards,

Mike
