I'm not sure that you need to define the page group as long as you have defined the class of the results.  Have you tried defining just the cpl page and it's results like this:

CPLPageList                         Code-Pega-List

CPLPageList.pxResults        <Results Class>

you can also specify ".pxPages()" as page name with the page obj class as the class of the page.

Maybe you can give us some additional details so we'd be able to help some more?

A code Pega List page cpl has pxResults (page List) for each of these lists there is page Group pxPages()(this page structure we get if we use joins in a report defination).

I have a repeated layout (pg List code-page-list)-each row has pxResults page,Now each row has a button ,for that button i need to call an Activity which takes a parameter, and parameter value = .pxPages(W).pxAssignedOperatorID

If in repeated Layout  for the button in Actions call activity and send parameter value as .pxPages(W).pxAssignedOperatorID   and save the section ---then I get the error message invalid page reference

thus I think i need to define the context in Pages and Classes in a section

which of the below options may be correct or I am missing anything?

cpl Code-Pega-List

cpl.pxResults <Class say A-B-C>

cpl.pxResults.pxPages  Assign-WorkList

-----or----

cpl Code-Pega-List

cpl.pxResults() <Class say A-B-C>

cpl.pxResults().pxPages()  Assign-WorkList

--or---

cpl Code-Pega-List

cpl.pxResults <Class say A-B-C>

cpl.pxResults.pxPages()  Assign-WorkList

should I use ()  fro pxResults while defining in Pages and Classes

and how should I type the parameter value for activity call on action for the button
