Re: [rules-users] Usings joins in decision tables

Hi, I assume you mean XLS decision tables, but if you mean in Guvnor the same principle applies. Something like this should be OK:- CONDITION | CONDITION ---------------------------------------- Header | SubHeader ---------------------------------------- $a : id != {param} | $b : id == {param} ---------------------------------------- null | $a null | $a null | $a null | $a Please note "null" above is the word null (no quotatioin marks) and not an empty value. You could use any other check in the Header column that is always true (e.g. "id > 0" in which case "0" would become the row value, etc).
