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.

Subject: [rules-users] verifying 'is not null' in decision table?
How can I verify if my condition attribute is not null in decision table?
I have a class -
Public Class Person {
String firstName = null;
String lastName = null ;
}
In my decision table I have to check if firstName and lastName are not null
and then fire actions.
How I can do this? I know I can get that through drl.
Thanks
