<br>for a fact, when I select a string type field from the drl guided editor in Guvnor and select <br> is null from the dropdown list of operators,<br><br>I get the following validation error when I do a validate on the rule.<br>
<br>no viable alternative at input 'null' in rule "Asset_Description_NullCheckRule"<br><br>when I do a View Source, it shows the source as <br><br>when<br> Asset( description == null null ) <br>
<br>Is this a bug ? <br><br>if I select the free form drl option and create the when condition as<br><br> Asset( description == null ) , it validates fine.<br><br>Thanks,<br><br>Ram<br></td></tr></tbody></table><br>_______________________________________________<br>
