Surfacing external types as custom activity parameters

Just wondering...

I have library which takes an enumerated type as a parameter so I exposed the interface through a promoted activity. As I dragged this activity into the workspace an exception is thrown saying it couldn't load the library whilst trying to serialize it.

Does anyone know if this is because my library is not in the correct location or is missing some attributes, or exposing the type in the interface just isn't supported?

Cheers,

I would bet you have to have an include (aka 'using') statement to reference the type. You cannot do this during an event, only in a stand-alone C# script as far as I can see, so I would bet it will never work.

Jerome, Options|Scripting|Namespace allows you select namespaces for use in code activities. Not had reason to check it myself but this is what the documentation indicates.

OK, many thanks for that. It sounds like a great idea - Ihad not considered this aspect.

Is that applied globally, though? I cannot allow any kind of access to types in my library, for example, unless they add this explicitly to the designer. Kind of useful in some ways, but does not go the distance for me....
