Ok, this one has kept me busy for quite a time. Hope someone of you can point me in the right direction:
In brief: How to overcome the limitations of NotesUIWorkspace.EditDocument which doesn’t allow to ‘switch’ to an UNSAVED document which is already open in the ui? I’m using the ‘newinstance’ parameter but it prompts me with ‘Cannot locate default form’ and when I’m setting one as default form, it opens the document to that form but in a new tab window instead switching to the already opened document.
What I want to achieve is, the user presses a button in a main form and a new (draft) document is created and opened in which the user may play around. This draft document I do not want to save.
I know there are some kind of other approaches like dialogboxes or saving the drafts and cleaning up afterwards, but the question remains: How to do this without saving the draft.
What I already have achieved is to get a permanent handle to the uidoc (as long as the main form stays open) by using a global variable of the main form. Unfortunatelly Lotus has seemed to miss out a function for just bringing a NotesUIdocument back to focus again.
In searching the forum I also found a post stating you should use NotesUIDocument.GotoField(“FieldName”) which happily changes focus as long as you are in debug mode, but fails if you try it without debugger.
This is really one of those little problems that can drive you nuts 
Any help on this would be highly appreciated.
Cheers
Jens
