Thank you very much.

I thought I had to put the parameters in to the Qrules and then call the query.

Much appreciated.

Hi Catharine,

I think I know why you are getting that null reference exception - can you delete this action(Query using a data connection : QdabraRules)? You don't have to set that action.

Attached a pic of how this rule should look.

Hi Catharine,

Well, I don't know that you want to completely delete that xpath! Perhaps it's acceptable to simply have a rule that sets the field's value to nothing (blank)?

Error using delete - what have I done wrong ?

I have a multi-selection box. If the user selects one particular option I want to delete any other items selected.

The field with the selection box has an xpath /my:myFields/my:SKUIntroductionGroup/my:RegionalGroup (in the main data source).

In the rules on that field I have added a rule (see attachment). The rule is only triggered if the value of RegionalGroup is Global. The command I enter is Delete /xpath=/my:myFields/my:SKUIntroductionGroup/my:RegionalGroup[. !="Global"]. Followed by a call to the qRules.

When I select the Global option I get the error message shown below. But when I clear that message it has done what I want.

There are no values displayed in Success; or Error fields of the QdabraRules data source. I am using version 2.0

System.NullReferenceException
Object reference not set to an instance of an object.
   at Qdabra.Tools.RulesLibrary.Commands.ExecuteCommand(Application application, XmlFormHostItem formHost, XPathNavigator commandsNavigator)
   at Qdabra.Tools.RulesLibrary.FormCode.QdabraRules__Command_Changed(Object sender, XmlEventArgs e)
   at Microsoft.Office.InfoPath.Internal.XmlEventHost.GenericProxy(Object genericDelegate, DataDOMEvent dataDOMEvent, InfoPathEvents type)
   at Microsoft.Office.InfoPath.Internal.XmlEventHost.ChangedProxy(DataDOMEvent dataDOMEvent)
   at Microsoft.Office.Interop.InfoPath.SemiTrust._DataDOMEventSink_SinkHelper.OnAfterChange(DataDOMEvent pDataDOMEvent)

I have obviously done something wrong - could you please advise.

Thank you

Catharine
