You can flush the html output stream, somebody else chime in as to exact
command, actually, I think you have to execute 2 similar 'flush' commands.
I tend to go manual:
-- unbind fields from do
-- unbind do from page
-- this_onBeforeDisplayEvent:
----execute dataobject, if not succeeded die or something
----if num rows <= 0 load 'empty' page.
-- Repeated1_onBeforeRowDisplayEvent
---- int rowindex = event.getRowIndex()
---- if rowindex >= do num rows (might have to execute getLastResults),
return STOP
---- for each formerly bound field, execute getValue on do or last results
set, using rowindex as row argument, apply result
to setValue on field.
