Hi Felix,

Which Data Types are you using on the specific Doc Type that throws an error? And could you add a stack trace for the error?

Hi Morten,

The Data Types i am using are:

1. Label
2. UComponents - > Multi Tree Picker
3. Content Picker
4. True/False
5. Upload
6. Textbox, multiple
7. Textstring

Here is the stack trace:

[NullReferenceException: Object reference not set to an instance of an object.]
   Sitereactor.StandardValues.businesslogic.FakeContentControl.AddControlNew(Property p, TabPage tp, String caption) +99
   Sitereactor.StandardValues.businesslogic.FakeContentControl.CreateChildControls() +745
   System.Web.UI.Control.EnsureChildControls() +181
   Sitereactor.StandardValues.businesslogic.FakeContentControl.OnInit(EventArgs e) +119
   System.Web.UI.Control.InitRecursive(Control namingContainer) +132
   System.Web.UI.Control.AddedControl(Control control, Int32 index) +276
   Sitereactor.StandardValues.EditStandardValue.OnInit(EventArgs e) +1180
   System.Web.UI.Control.InitRecursive(Control namingContainer) +132
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1953

would like to add that its not the UComponents Multi Tree picker causing the issue as  i am using it on another doc type that i can set default values for. The rest of the controls are standard umbraco out of the box controls.

Hi Felix,

I have tested all the datatypes you listed except for the UComponents - > Multi Tree Picker, so that might be the cause of the problem.
Is it possible for you to create a new DocType and add the same properties except the Multi Tree Picker and see if it works? Or simply create a DocType with only the Multi Tree Picker and see if it fails.

Okay, well thats strange. I'm pretty sure I tested all the standard umbraco datatypes.

Well, I'll have to check them one by one and in the combination you mentioned to see if I can reproduce the error. If you could help out in isolating which DataType is causing the problem that would be great.
