Hi Nazar,
yes some ideas :-), we had a simular problem last week.
If you need a action method executed on server you can add a invisible
tc:link element.
If you don't need to execute a action, just rerender the page you can
use the id of the tx:selectOneChoice in Tobago.submitAction(). (Only
with latest sources, i fixed this in UIPage last friday)
But you need the *full* generated html id, e.g including the id of page
tag, not just the 'instances_apply_filter'.
You can render (nearly) invisible tc:link with this:
<tc:link action="#{instances.filterChange}" id="filterChange" />
if your page contains a empty tc:cell just render this into, or add it
somewhere to a panel and set layout for this cell to '1px' (this is what
i mean with nearly invisible, you can't see the link but it needs
additional 1px space)
Than you can invoke Tobago.submitAction('<pageid>:filterChange') to
execute this action on server.
Hope this helps.
Regards,
Volker
