How to pass a list of class references to method

Hi,

I have a workflow container element of the type class reference and marked as multiline. Now I want to provide this table of class references as import parameter to a method - of cause using a standard task in the middle.

In order to tell the method that a table is expected I have created a structure with one element - and with the type: 3 type ref to and my class as the component type. I have created a table type for this structure.

Then the import parameter of the method has this tabletype as the type. The standard task defined for the method also gets this element with the table type as reference.

But I get an error when doing the bindiing from the workflow to the standard task:

"An object compatible with '[CL.ZCL_MY_WORKFLOW_CLASS]' was expected as the target expression"

How can I come across this issue - without programmed binding...

Thanks,

Claus.
