My package already contains two SnapSections, both of which load with no problems. My SnapSections are all derived from the same base class. The screen definition is as follows:

Code: Select all

<ScreenDefinition>
	<ScreenName>OneClient Lookup</ScreenName>
	<Priority>0</Priority>
	<Context>Order</Context>
	<SnapSection>
	      <Name>OneClientLookupSnapSection</Name>
	</SnapSection>
	</ScreenDefinition>
I'm not doing any different than any of the other SnapSections, nor does the SnapSection do any out of the ordinary (it only contains a single button).

Any ideas?

Typically, this error results from a failure in the constructor of the snap section or a failure in the Initialize(...) method of the snap section. That would be the point where I would start to look.

Thanks Phil, we solved the problem. It turned out the class name didn't match. One of those gotcha's if you don't pay close attention. Thanks for your help.
