[Openflow-dev] completeWorkitem

[Peter E. <P.E...@er...>]

I still can't puzzle out how to automate continuation from a DTML application.

First, attempting to follow Daniele's instruction, I tried
<dtml-call "_['openflow_id'].completeWorkitem(instance_id, workitem_id)">
directly in the application, but this causes the following Zope error.

(if the application has manual start, this happens when I press 'Start 
application' from the Worklist)

          Error Type: AttributeError
          Error Value: completeWorkitem

Traceback (innermost last):

I then thought this is the wrong time to call completeWorkitem, as it happens 
when rendering the page for the user. The user should select something or 
pressing a button to do it, i.e. making a decision to complete the Workitem.

So I tried creating another document (or a Script may be better), and made the 
first document access that either by <a href=(etc)> or <form (etc)>. But I 
couldn't see how to pass in the OpenFlow parameters to that other document. Is 
this anything like the right idea?

Help please!
