WebTab in Repeater Error

I have a WebTab in a Repeater that is not working.  When I DataBind() the repeater, I get the following error:

Any Ideas?

    Hello Cheri,

    Thank you for posting in our community.

    In order to provide you with more accurate support I will need a small sample that I can run and debug on my side. I assume that you are using the WebTab in the ItemTemplate of the Repeater, however, the exception thrown is too generic and having a sample that reproduces the issue will give me the opportunity to debug and find the root cause of the behavior. Please remove any external dependencies (use dummy data source) and attach the sample in this thread.

    Looking forward to hearing from you.
