[rules-users] OR condition in decision tables

[Edson Tirelli]

   Mahesh,

   I'm not a decision table specialist, but I see a couple choices I would
try:

1. Simplest: since each line is a rule, just use 2 lines that will break
down into 2 rules, each testing for a different value. Use cell merges for
conditions that have the same value on multiple lines.

2. "in" operator: for cases like you showed, try using the "in" operator:
field in ( $param ). So in the table cell, the user just use a list of
values separated by coma, generating a pattern like:

applicant : Applicant( applicantType in ( "authenticated", "existing" ) )

   Not sure if there are other, better ways to do it.
