[rules-users] Checking multiple null values

Hi. I have a bean which has some properties; p1, p2 ... px. I would like to write a rule in a decision table that tests if some of these parameters are null. I wrote it in this way: +---------------+---------------+---------------+ |CONDITION |CONDITION |CONDITION | |myBean:Bean | |$param == null |$param == null |$param == null | |Rule1 |Rule2 |Rule3 | |p1 |p2 | | |p1 |p2 |p3 | |p4 | | | +---------------+---------------+---------------+ I would like to avoid writing n columns. It is possible to write such a rule using only one column?
