Applying a large string length attribute like [StringLength(4000)] randomly exceptions

[jeremycook]

It may be related to the TextGenerator's lorem ipsum having a length of 907. I see that you cap the length in one of TextGenerator's constructors, but I also see that the Length setter is public and therefore could be set to a number larger than 907.

Here's a stack trace:
