Re: [rules-users] verifying 'is not null' in decision table?

The key thing to remember with decision tables is that currently a column is only included if there is a value in the rule row and that value will always be included in the rule. The easiest way to do this is to have a condition in the form "firstName != $param" and then have null as the cell value. The other solution if you want separate rules for each field which cannot be null is to have it in the form "$param != null" and enter the field name as the cell value.
