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}"

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? I need the two different eval
conditions, and sometimes they have to be combined.
Thanks
Markus
