    error viewing document types

    Hello,

    While actively developing my new umbraco site, I now get the YSOD trying to view DocumentTypes, and all my content has been move into the recycle bin. Restarting IIS didn't help; exporting & reimporting the Document Types didn't help. Using Umb 4.5.2.

    Trace:

    [NullReferenceException: Object reference not set to an instance of an object.]
   umbraco.controls.ContentTypeControlNew.setupInfoPane() +631
   umbraco.controls.ContentTypeControlNew.OnInit(EventArgs e) +158
   System.Web.UI.Control.InitRecursive(Control namingContainer) +333
   System.Web.UI.Control.InitRecursive(Control namingContainer) +210
   System.Web.UI.Control.InitRecursive(Control namingContainer) +210

   System.Web.UI.Control.InitRecursive(Control namingContainer) +210
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +378

    Any ideas? I've seen a few similar reports on the forum, no solution.

    Hmm, well, looking around the settings tab I expanded the stylesheets item, which took a while to draw, then the document types started working. Very mysterious.

    Also, right before it started working again, I shut down Visual Studio, which I was using to edit the template files.

    I did also get this exception when trying to view document types. A iisreset helped me out
