I'm using the DataTypeService to get the "nice text" (GetPreValueAsString) for a selected dropdownlist item. But on the first load of the website, I receive the following YSOD:
It looks as if something is not completely initialized when the call to the DataTypeService is invoked, because I only receive this message on the first run (after building). When I access the Umbraco backend in another page and then switch back to the actual page, the page loads just fine.
I should perhaps not that I'm using Zbu's ModelBuilder to generate strongtyped models for my document types (which works just fine).

A coworker of mine is periodically encountering this too. Umbraco 7.2.4. Not using Zbu's ModelBuilder.
Here's an Umbraco issue somebody submitted related to this: http://issues.umbraco.org/issue/U4-6289
I had a similar issue that I fixed by using this method instead umbraco.library.GetPreValueAsString
Woah. That fixed it for me, too...
is working on a reply...
