[rules-users] Problems with OR

[skasab2s]

Hello,

we are using Drools Expert. We have a rule which should fire if at least one
of the object attributes are not empty. This is my pattern:

( TblVersichKlinik(versicherung != null, versicherung != " ") 
or
(TblVersichKlinik(zusatzversicherung !=null, zusatzversicherung != " ")) )
  
The problem is the following: when BOTH conditions are fulfilled, the rule
fires twice, so I get redundant results in my final result, and this is not
wanted.

Is there a way to solve the problem? Any ideas ?

Thanks a lot and many regards!
