[htmltmpl] firing multiple templates

[Puneet K. <pk...@ei...>]

So I am working with frames (I have to). Different scripts populate 
different templates in different frames -- at different times. Now I 
want to press one button in one frame, and update two (or more) frames 
with respectively different templates.

I have --

frame1.cgi --> frame1.tmpl --> frame1
frame2.cgi --> frame2.tmpl --> frame2
frame3.cgi --> frame3.tmpl --> frame3
frame4.cgi --> frame4.tmpl --> frame4

I want to do --

frame1
frame2
frame3 --> frame3.cgi --> frame3.tmpl --> frame3
                       |
frame4                |-> frame4.tmpl --> frame4


Needless to say... there is stuff in frame3.cgi that is powering stuff 
in frame3.tmpl as well as in frame4.tmpl.

(
I am clicking on a map in one frame which is causing features to be 
selected and the map to be redrawn with the selection visible. At the 
same time, I want to query the underlying database for the selected 
features and display them in another frame.
)

How do I do this?
