DataSource does not exists or is not part of the first root

Dear all,

I got an error in Version 10.0.15 that not appears in 10.0.13.

I extend the DirPartyLocationPostalAddressV2Entity which includes dataSource LogisticsLocationExt. The field i like to put in the entity field list is SalesCalendarId. In Version 10.0.13 there was no problem to do that, in version 10.0.15 I got this error...

Description Project File Line
Path: [AxDataEntityViewExtension/DirPartyLocationPostalAddressV2Entity.Extension/Fields/SalesCalendarId/DataSource]:Data source 'LogisticsLocationExt' does not exist or is not part of the first root data source in the query.

I checked out my model parameter... the model is linked to ApplicationSuite and ApplicationSuitePlatform... so everything should be ok?

Can anybody give a solution?

Regards

Christian

    This data source is added to the base entity by DirPartyLocationPostalAddressV2Entity.ApplicationSuite_Extension.

    So basically your extension would like to use a field from a data source that is added by another extension.

    Are you saying that your extension works / compiles with 10.0.13 but not with 10.0.15?

    (By the way, remember to never call your extensions simply .Extension because of potential naming conflicts which could block installing MS updates in your system).

    Hi Nikolaos,

    first... I did not call my extension only "extension", surely there is a prefix... ;-) but thx for the advice...

    And yes, there was no compile/runtime error in 10.0.13. I use this extension yet... yesterday I install version 10.0.15 and I got this error...

    And I think it should be possible to use extension fields!?

    Ok, thanks for the info.

    In your error message it's just ".Extension": AxDataEntityViewExtension/DirPartyLocationPostalAddressV2Entity.Extension/Fields/SalesCalendarId/DataSource

    But I assume this is still your extension?

    Could you check the field properties in Visual Studio - do you see the LogisticsLocationExt data source in the lookup for the Data source property?

    Yes... that is my extension... and yes I can see and select the LogisticsLocationExt in lookup for DataSource... and I can plug it by drag and drop...
