I want to find all calls to Cosmos.execute(..) such that the calls occur in subclasses of class Concern? The query I would use is: call( * Cosmos.execute(..)) && within(sourceof(relationship extends(class * ,class Concern))) This query results in a Syntax Error. Below, you'll find Peri's response on the CME Users list in an abriged form: Okay, I've looked into this, and it's a problem with our query parser--it's treating "within" as an identifier instead of as a reserved word. (This traces back to a problem with our parser generator, which I'm in the process of replacing.) <snip> I'll do the interim fix, which is to disallow the use of AspectJ pointcut tokens as identifiers, and then probably will be able to address this issue properly when I've finished the move to the new parser generator. (Sorry, this problem probably arose as the result of a fix to a different problem in the parser generator; I'm really surprised that the test suite didn't pick it up, because we have test cases for it, but I'll update those as well, so this was a particularly good catch--thanks.) <snip> Sorry it caused you problems, but fortunately, I think it's a 5-minute workaround, so I may even have you running today :-). Thanks for raising the issue!
Problem turns out to be that within() only is defined on named types and packages at present, as in AJ--you can't use general queries as parameters at present, and you were trying to use it (entirely reasonably) with a query as a parameter. I think there's a deadly parser ambiguity in the current parser generator if I change it to accept any query as a parameter, but I will check.
