[rules-users] trouble adding newline to DSL

[Edson Tirelli]

   Hi Matt,

   If I remember correctly, you need to use \\n to break lines. Also, I
think this should work:

rd: RuleData(offerId == "{offer}", uc : userContext)  not ( Account(where
{constraints}) from uc.accounts)

    If it is not working, maybe you can open a jira for it? Meanwhile, as a
work around try adding an "and" there:

rd: RuleData(offerId == "{offer}", uc : userContext)  and not (
Account(where {constraints}) from uc.accounts)

    AND is supposed to be implicit, but making it explicit should create no
problems.
