In current kie-drools-wb-6.1.0-SNAPSHOT-jboss-as7.0 and kie-wb-6.1.0-SNAPSHOT-jboss-as7 it isn't possible to use DSL sentences with more than one variable.

to reproduce:

append in uf-playground mortgages ApplicatonDsl:

[when]When the credit rating is {rating:ENUM:Applicant.creditRating} and date after {dos:DATE:default} = applicant:Applicant(creditRating=="{rating}" && applicationDate>"{dos}")

create a new GUIDED RULE (WITH DSL) and use the new dsl when sentence

view source:

when 
 applicant:Applicant(creditRating=="AA and date after 13-Feb-2014")
