This is a bug in the DSL engine. May I ask you please to submit a JIRA for it? Meanwhile, I advise you to avoid eval, since it is more performant and more clear to use regular constraints. The following grammar entries are equivalent to yours, but much more performant: [when]- Title equals "{value}"=title == "{value}" [when]- Event equals "{value}"=id == "{value}" []s Edson 2007/10/8, Markus Helbig < mhelbig81(a)googlemail.com&gt;: > > Hi, > given the following DSL > > > [when]of type Item=Item() > [when]- Title equals "{value}"=eval(title.isEqual("{value}") > [when]- Event equals "{value}"=eval(id.isEqual("{value}") > [then]Log : "{message}"= System.out.println("{message}"); > > > > the dslr File: > > expander Test.dsl > > rule "Your First Rule" > when > $p : of type Item > - Title equals "test" > - Event equals "test" > then > #actions > end > > resolves to (could be seen in the drl viewer) > > rule "Your First Rule" > > when > $p :Item( eval( title.isEqual("test", eval(id.isEqual("test") ) ) > then > #actions > > end > > > so this of course does not work because of the brackets in "eval" > > How could i solve this problem?
