[christopher barham (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBRULES-1044?page=all ]

christopher barham updated JBRULES-1044:
----------------------------------------


Similar issue on import in the DRL file...  

Example Rule:

package com.sample

import com.dialect.rules.DroolsTest.Message;

rule "Hello World"
  when
    m : Message( status == Message.HELLO, message : message )
  then
    System.out.println( message );
    m.setMessage( "Goodbye cruel world" );
    m.setStatus( Message.GOODBYE );
    update( m );
end

rule "GoodBye"
  no-loop true
  when
    m : Message( status == Message.GOODBYE, message : message )
  then
    System.out.println( message );
    m.setMessage( message );

end


gives stack trace:

org.drools.rule.InvalidRulePackage: [3,11]: unknown:3:11 mismatched token '[@10,31:37='dialect',<32>,3:11]' expecting set nullorg.drools.compiler.ImportError at 1bc4459

> Although not mentioned in the Online documentation, it appears Dialect is now a reserved word, the Eclipse IDE highlights this in a rule.  Changing the (Eclipse generated) sample project to be in package com.dialect.rules instead of com.sample results in the stack trace below.  This is a problem as my company is called Dialect so all my pacakges have the word in there :-) :
> org.drools.compiler.DroolsParserException: Unknown error while parsing. This is a bug. Please contact the Development team.
