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}"
