Hi Radek,

I solved this problem by doing following:
Generate the ecore mete model code, and export the model project as 
plugin jar, and put the jar under Eclipse plugin folder. Then we can 
define the IN parameter without problem.

So I guess that QVT needs Ecore meta model code in order to run?
can it automatically generate code from meta model if this is the case? 
Since the project contains the corresponding metat models.

We tried to define the mapping between namespace and the meta model 
through 'QVT Settings/Metamodel Mappi. But seems didn't work for us.

I am not sure what it means "Do you intend to you use dynamic model 
instance or generated java model instance in your transformation"? Can I 
understand that it is what we did as describe above through generating 
meta model code?

Thanks very much,

David
