An item with the same key has already been added - XAF Windows Only

created 7 years ago

Hi

I have been working on a project using the XAF framework, focusing on the Web aspect of the project, although the windows and mobile projects are already part of the solution, i now need to get the windows project working however when i load the project i am presented with the "An item with the same key has already been added", i am unsure as to why i have this problem, if i had accidentally used  the same key (although i can not see a duplicate) then would the web project not also present the same problem?

I have not made any changes to the Windows application model, however if i hide all of the navigation items the error does not appear, but of course i can not navigate/use my application.

FYI - after i click OK on the error message if i attempt to click on any of the navigation items such as My Details then i am again presented with the error message and the required view is not displayed.

Also the Mobile application works fine.

Can you point me in the necessary direction so that i can resolve this issue

Thanks

Andrew

Hello Andrew,

This issue occurs, because actions with the same ID are added to one of the application's Action Containers. Since XAF does not allow registering multiple actions with the same ID, it is likely that the same action has been added twice, or an action has been registered after the Application Model is validated. We cannot determine the precise cause of this error by the Call Stack. Please check if one of the following events is handled in your application:
ActionControlsSiteController.CustomizeContainerActions
ActionControlsSiteController.CustomAddActionControlToContainer
ActionControlContainerManager.CustomizeContainerActions

If this does not help, you can determine which Action and Action Container cause this issue by debugging our sources using PDB files - How can I debug DevExpress .NET source code using PDB files. Alternatively, provide a sample project where the issue can be reproduced.
