Out Of Memory.. again!

Yesterday I plugged my quick-n-dirty Gallery module into DotNetNuke (I developed the most I could as a separate User control), and Bang! I've got this weird OutOfMemoryException. Now, I'm pretty sure that even the DotNetbeast can't eat all my virtual memory, so it should have been something else. Now the funny part: a quick Googling revealed that some poor user already have had this problem (and solved it by himself). And guess what: it was me! At least nobody else posted a message about it with a full stack trace. But I've got a pretty good reason to think that this particular error is related to me in some esoteric way.

Maybe it's a sign that I forgot something very important? Or I remember too much?

Anyway, for those who are interested in solving the problem. I've been using an ObjectDataSource (yes I'm a script kiddie), and it was referring to a class in my DAL project. It worked fine in a standalone project, but when I registered it in DotNetNuke and moved the DAL assembly to the bin, the error occurred. Acually, it has nothing to do with memory. The name of my class was written without the assembly name. Once I added it, everything went OK.

The stack trace is below. As you can see, there's not a line of my code, so there's no chance I could even debug it. Also, the exception happens at the _GetType method, which is most probably native, so perhaps they just throw an OutOfMemoryException then they don't know what's just happened.

So, if you get an OutOfMemoryException when doing some reflection, don't get scared, just double check your type names and make sure they are fully qualified.
