Like it's possible to modify the content of a group I would like to modify the content of a tab using DAML. I tried:
<ArcGIS>
<module>
...
<updateModule refID="ut_desktop_addin">
<tabs>
<updateTab refID="ut_desktop_addin_tab">
<insertGroup refID="ut_jobmanagement_group" />
</updateTab>
</tabs>
</updateModule>
</modules>
</ArcGIS>
But that does not work. The new group won't show up.
The point is: I do not want to modify an existing Esri tab but I want to add a new group to one tab that comes with another of our AddIns. Is that generally possible? Or can I modify Esri Tabs and Groups only?
