Summary

The pyPrimaryPageName parameter passed in a URL can reference only a top-level clipboard page. Any sub-page reference is stripped off.

Why is this?

Suggested Approach

Clipboard pages are convenient to access, but present some risk and expense to the system - which must, among other precautions, make sure the page that you are referencing is present.  Sometimes the clipboard may not be in the condition that you expect or require. 

By restricting the pyPrimaryPageName parameter to top level pages by name, Process Commander can better manage the transaction and ensure the necessary page is available.  The further down into embedded pages it has to support such parameters, the harder it is to manage.  Thus, as you have seen, the server strips off embedded page references.

However, you can use this workaround:  

1. Set a second parameter whose value is the path to the embedded page you wish to reference
2. Pass both parameters to resolve to the fully-qualified page.
