Don't use not(exists( X() )).
   not( X() ) 
means "there is no X". The error may be due to constraints, but you'd have to show us the entire DSLR condition and its DSL definition.

Hi,

 

  I have been trying to add not exists constraint in dslr but its failing to parse the dslr. Here is what I am trying to do in DSLR

[when][][Tt]here is at least one {entity}= not(exists {entity}: {entity}())

If I simply use the exists constraint here then it works well. But then after adding not to it, its not getting parsed correctly.

error I am geeting is:

[10,27]: [ERR 102] Line 10:27 mismatched input ',' expecting ')' in rule "Rule1" in pattern Person

not sure whats going wrong here, if it is expected to work this way?

thanks,

-m
