Hi Everyone,

Need urgent help on below issue.

I have been working on migrating Ax2012 code to D365.

I have the overlayered objects in release branch of VSTS. I removed the overlayering of all objects and refactored them.

But since last few days , if I try to open few extended forms out of those objects in VS designer, I am facing below error,

5415.VS-error2.png

Post Script: This not the case with all extensions that I have created but with few of them. When I tried the model build in error window I got below error related to same objects,

"An unhandled exception was thrown while validating CaseDetailCreate.SIExtension with callstack System.ArgumentException: An item with the same key has already been added."

Please suggest solution on this.

I have the same question (0)

Have you checked if you have an object called CaseDetailCreate.SIExtension also in some other package?

Perhaps you copied it from ApplicationSuite package to your own package, but forgot to remove the old version?

Hi Nikoloas,

Thanks for the reply. But I tried finding out the name of element in all packages but did not find any duplicate name object in other packages. Also I would like to go through one more error related to same, please confirm whether it is clarify anything to you or not.

C:\AOSService\PackagesLocalDirectory\SI\BuildProjectResult.log(1119):Metadata Error: AxFormExtension/CaseDetailCreate.SIExtension/Controls/Copyqsjp02rw1/Controls/FSGeneralGroupBottomCol1/Controls/CategoryGroup/Controls/FSCaseIdGroup/Name: The duplicate name 'GeneralGroup_CaseId' was detected. The duplication is either in the base element that extension applies to or in other sibling extensions.

GeneralGroup_CaseId is a control in CaseDetailCreate form. So your extension can't have any element with the same name.

Please try to rename it (you should always use your own prefix with all your custom objects) and see if your problem is resolved.

Hi Nikolaos, that makes sense. But how could I rename the control now, as I am unable to open the object in Designer. Is there any alternative way to modify the same XML?

Yes, just locate the XML file of your form extension and rename it there.
