This datatype looks awesome! Unfortunately I have some trouble with it, I've installed the package and added the Pixlr datatype to a document type.

Now when I open documents of that type, I immediately get an exception (see below).

I've done an iisreset, and tried to do a republish of all of the parent including childnodes, but the error stays. Once I remove the datatype from the document type, all is well.

Exception:

System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object.
