User select shape / dynamic read featuretypes / Write fgdb

My tasks to do with FME looks like this:

 

- Start the workspace and choose a shapefile.(The schema is not known before)

 

- Write the feature type with all attributes to a Filegeodatabase.

 

 

I can create a workspace with shapefile reader and dynamic fgd writer and a published parameter to get the input from the user.

 

But my problem is the reader which needs some predefined features.

 

 

If i select a shape file I get the following "unexpected Input" error: "some features were read that did not match a reader feature type...."

 

 

Is there a way to define the feature at runtime out of the input? Something like a dynamic schema reader?

 

 

Cheers
