Hello.
I want to check the syntax of an OCL query, before its execution:
// Build the select query statement
SELECT statement = new SELECT(SELECT.UNBOUNDED, false,
new FROM(context), new WHERE(condition), monitor);
where "condition" has the type: "BooleanOCLCondition".
I need to check the syntax before because I get empty results with wrong expressions, and I would like to make the distinction between empty result by one right OCL expression, and empty result by an OCL expression with wrong syntax.
Have you got any suggestion?
Thanks in advance.
Best regards.
Carlos.

Hi Carlos
OCL has no 'new' capability. I suspect you are using perhaps EMF Query.
try the EMFT newsgroup.
However if you formulate the problems as OCL, you can do syntax (but
only partial semantic) checking with the OCLinEcore editor. Of course
you can use the Interactive OCL Console to practice OCL queries on models.
