This happens in web version with every view configured with CollectionEditMode = Edit being the nested view fom a many to many associated object. If you make the selection of an object with the link action and before saving decide to access to that object then it raises the exception:
C#Type: InvalidOperationException
Message: An error with number 1007 has occurred.
Error message: Unable to execute disabled or inactive action ListViewShowObject. Disable reasons: Requires a single object selected, inactive reasons
The related object has a unique Id Key (Guid) so it is not related to composed keys well known error.
Hello Joe,
We could not replicate this behavior using our demos. Would you please attach your problematic test project along with step-by-step instructions that lead to the error you received? This essential information will help us research and avoid this behavior much faster. Thanks.
You're right Dennis, I have made a new test project and it works so I must think there is something wrong in my project. Could you please advise me about where shoud I research? Searching another isues with the same error message I can't find similarities with my code.
Thanks for your reply, Jose.
It is difficult to tell you what is causing this error in your project without debugging it locally. Would you please add problematic business classes from your real project into one of our demos or a brand new solution and replicate the error there? If you cannot isolate this behavior within a small sample, attach your entire project here, but I must warn you that it will take more time to research it.
Hello Jose.
Thanks for your project. We have replicated the issue. It seems to be related to the fact that the DataAccessMode of the "MailMessage_MailTo_ListView" list view is set to Server. We need additional time to research it. Currently, you can set the DataAccessMode property of this view to Client, as a workaround.
