The issue was that the "value" was added to the DRL even though the operator "not null" didn't need a value. Another work around is to first use "equals", then enter a literal value (a single space, or empty string) and then the "not null" operator. Your work around seems simpler though. 2011/9/5 puja nandamuri <med_9...@yahoo.com> what do you think of using the function route as a work around? do you see any issues with using that ? --- On Mon, 9/5/11, Michael Anstis <michael.ans...@gmail.com> wrote: From: Michael Anstis <michael.ans...@gmail.com> Subject: Re: [rules-users] is null or is not Null failing for a String field check in Guvnor drl To: "Rules Users List" <rules-users@lists.jboss.org> Date: Monday, September 5, 2011, 1:04 PM Shame :( 5.2.0.Final could well be fixed... are you able to try that? CR! was effectively pre-release. 2011/9/5 puja nandamuri <med_9...@yahoo.com> Michael, Thanks. Yes, I am using 5.2.0.CR1.I do not have a choice to move to 5.3 at this point. as an alternate, I am using the following work around. to be able to do 'is null' or 'is not null' for checking null condition on a field, I select 'equal to' as the operator and then, I click on the function button instead of literal value . In the text box that comes up, I enter null Doing this validates the condition successfully and I am able to run the test scenario successfully .similarly, I select 'not equal to' operator for checking is not null condition and then in the function text box, I enter null. --- On Mon, 9/5/11, Michael Anstis <michael.ans...@gmail.com> wrote: From: Michael Anstis <michael.ans...@gmail.com> Subject: Re: [rules-users] is null or is not Null failing for a String field check in Guvnor drl To: "Rules Users List" <rules-users@lists.jboss.org> Date: Monday, September 5, 2011, 12:13 PM It was a bug but was fixed a while ago. I can't recall if it made 5.2 - but it definately doesn't exist in 5.3.0.CR1 (or master branch as of today - I just checked). 2011/9/5 puja nandamuri <med_9...@yahoo.com> Hi , when using a business rule guided editor , for a fact, when I select a string type field from the drl guided editor in Guvnor and select is null from the dropdown list of operators, I get the following validation error when I do a validate on the rule. no viable alternative at input 'null' in rule "Asset_Description_NullCheckRule" when I do a View Source, it shows the source as when Asset( description == null null ) Is this a bug ? if I select the free form drl option and create the when condition as Asset( description == null ) , it validates fine.
