SetDefaultValues: CategoryList

I have used the override of SetDefaultValues many times with no problems to set values of properties. Now, however, I have a property which is a CategoryList and I get an error when I try to set it is SetDefaultValues. Error log reproduced below.

Anothe thing which is confusing me is that, when debugging this code, the method SetDefaultValues is called twice. As soon as I create the new page it is called. Then I am prompted for a name for the page, and the method is executed again. Why is this?

Thanks.

Error log:

Anyone solved this issue. I have the same ting but that is when we import /transfer data from one instance to an other instance of EpiServer. It seems like bug?!

Hej  Peter Neuss  could you write your code snippet here, where you use SetDefaultValues(contentType) ? how do you populate default value.?
