Entity Framework with MYSql, return no column in complex entity return type

Question

I'm using MySQL in combination with an edmx file. I'm facing a problem when adding a function to stored procedure. When I select "complex type" and press the "get column information" button I receive the following message: "The selected stored procedure returns no columns."

When I create the same procedure in SQL Server and then added the function to a new edmx file, its creating the complex type perfectly.

Thanks,
