Getting my report portlet, to link to my form portlet

Question

I am attempting to put together a portal page that has the
following components:
A- Form Portlet with a Pull Down that links to a
B- Report Portlet built by a SQL Statement that links to a
C- Form Portlet that acts like a Property Sheet from the Report
A drives B that drives C, all within the same page, using page
refreshes, to show the linkage after clicks.
I have been able to put this together because, I have used the
explanation found in the Advanced Portal Presentation put
together by Kenneth Atkins, that can be found at
http://www.arrowsent.com.
It provides a really good explanation on how to link portal
components(forms, reports, etc) using the pdk.
I have attempted to use what he has put together, and in general,
it is all working, as he has explained in your ppt, except the
very last bit. Where B refreshes C
That is, my pull down form refreshes the report, just fine.
and then when I click on my "item" in the report, to refresh my
detail form, it does that, but what it brings, up is the item, I
clicked on previously. It's like the "C" Component wants to show
the previously selected item, rather than the current one.
I am using Portal 3.0.9, on 8.1.7, and this behaviour is
consistent on both Solaris and Win2000
I have included the PL/SQL code that is inserted in "Before page
processing section" of the "C" form.
My guess is, that I have syntax wrong in either the do_event line
or I am not setting the rowid for the auto_query to work
properly.

-- Tell the component that the query is coming from a link, and
that the rowid

p_session.set_value (p_block_name=>'DEFAULT',
p_attribute_name=>'_CALLED_FROM_LINK',p_value=>'ROWID');
-- Pass the rowid of the context record to query.
p_session.set_value (p_block_name=> 'DEFAULT',
p_attribute_name=> '_ROWID',p_value=> v_rowid);
-- Now do the actual query, using the query button processing
in the target module
-- this seems to execute with the rowid in context of the
previous instance i.e, Out of Synch by 1 element in an array

'QUERY_BOTTOM', 1, 'ON_CLICK', True, '', p_session);
-- Save the session information, which includes the
p_session.save_session;
