Any more details you can share, strack trace of the error... if possible

Thanks Tim,

It worked fine until I amende the doctype to allow a choice of templates which didn't work, so I chabged the template to the original and then I got the error and now it wont let me change the template at all. The error message is:

An item with the same key has already been added.

and the stack trace is:

[ArgumentException: An item with the same key has already been added.]
   System.ThrowHelper.ThrowArgumentException(ExceptionResource resource) +52
   System.Collections.Generic.Dictionary`2.Insert(TKey key, TValue value, Boolean add) +9378779

   System.Web.UI.Page.RaiseChangedEvents() +134
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +5201

hope you can help as I am stuck with a totally inappropriate template.

So this is happening when you are using the save as umbraco document workflow type, right?

Is this happening for every document type you choice or only a specific one?

Yes, exactly that.

Yes, now it wont let me change document type, it happens with all document types. I am stuck with the site document type.

Will do, I'll get back to you with the results.

Ok Tim, deleting and recreating done the trick, don't know why I didn't do that in the first place!!!

Thanks for your support.
