GP - consolidating structured parameters problem

Question

Hi,
I have a problem when consolidating parameters of the same structure type.
I want to consolidate parameters between two Web Service CO. The output parameter of the first has the same type as the input parameter of the second. They are structures (the parameters are lists of java objects, which themself contain lists of objects and other string objects. That means
List1
   List2
   String).
So, when I consolidate them (I group the List2 structures), as an input to the second CO I get the Strings matched but only the last list element of List2, the others are overwritten maybe.
I have read in the SAP Help Pages in the consolidating parameter page that :
The Group option is enabled only for:
○       Standard parameters of the same type (for example, String, Integer, Time)
○       Structure (and Structure Template) parameters, regardless of their internal hierarchy
So, I thought that I can consolidate parameters with arbitrary hierarchy.
Do I understand that wrongly or is there any way to make such thing?
Thanks in advance
Best regards,
Vera

I don't think GP forgot your changes here.
I assume you don't have any problems with defining the GP interfaces for your 3 actions (implementing GetDescription).
Now when you implement the Execute or Complete method to set or get the GP List structure or array you've defined, you need to:
- make sure that in the A1 callable object, you're passing correctly the content of the Webdynpro array to the GP interface structure.
- make sure that in the A2 callable object, you're passing correctly the content of the GP interface structure to the Webdynpro array.
Your problem is a Webdynpro problem not GP. You can use the mechanism of looping through the first array and add element or row to the second array.
That's a good webdynpro exercise and enjoy it!
