Description Greg Watson CLA 2011-11-03 08:35:09 EDT 
I created a new view called PTP. However when I set this as the default view on my configuration page, I now see the following NPE. The "Default View" field is now empty and below it is a link "ERROR". If I click on this link, it says "Access Denied: gwatson is missing the Create permission". I am unable to change the default view to anything else.

I'm not able to reproduce this in Hudson 3.0.0. Couple of notes

- The new view must be created under MyViews. If the new view is created in the global views, it will not be used as default view under my view. In that case trying to assign a non existing view will result in a red error message as shown in attachment1 [details].

- After creating the view in MyViews and setting it as default view in the User Configuration page should set that as the default view in the MyViews Dashboard as shown in attachment 2 [details].
