DotNetNuke.Common.Utilities.CBO.FillObject causes an exception with nullable fields.

In my case the HydrateObject() method tried to convert an Int to Int? on line 205 in CBO.vb. This causes an exception Invalid cast from 'System.Int32' to 'System.Nullable`1[[System.Int32, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]'.

This is a known bug in the 2.0 framework http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=93465

Hi,

I'm experiencing the same problem.

  1. It's not really clear if this a DNN/ASP.NET bug that will be fixed in 4.8.1 or that I need to adapt my module code?
  2. And if I need to adapt my code, how should that be done?

Thanks!

It sounds like this is something that the core team will address...

As for a work around, you would most likely need to implement your own hydration methods to deal with the values.  You could use iHydratable to your advantage in this case.

It is important to realise that the CBO class is not designed to handle every use case.

Mitchell's answer is the best solution.  If CBO does not work for you then implement IHydratable, which gives you full control over the hydration.
