ApEx Development Team: tab clear cache - new feature?

Question

Hi ApEx Development Team!
I searched the forum and found, that many have (had) the same problem like me:
Why isn't it possible to clear the cache by clicking on a tab? Why is it only possible for parent tabs?
Wouldn't it be a nice feature for the next version of ApEx? This feature exists already, only not for the standard tabs...
Regards,
Sofie

Apologies to dig up old thread but I ran into this problem and thought I'd share my solution as well (for search engine)There is no point in doing this. There are thousands of threads in this forum that are unanswered, or contain solutions that are suboptimal or that have been superseded. They can't all be updated "for search engine"...
1) Edit the tab property where you want your page's cached removed. In My case it I had a tab pointing to page 6 and I needed page 6's cache cleared when I clicked on it.
2) Edit the condition for the tab deisplay --> Function returning boolean.
3) In the function body put the following code:
begin
if :APP_PAGE_ID != 6 THEN
apex_application.clear_page_cache(6);
END IF;
RETURN TRUE;
end; The expression will always evaluate to true, and will clear cache from page 6 if clicked from any other page that is not page 6.
However if you want to apply condition to the page as well. (say and admin page based on :APP_USER property) then wrap the return true in another If-statement as well.I subscribe to the old-school idea that state-changing side-effects in functions are evil. Using Condition code in this unexpected way will make an application much harder to debug and maintain. If I came across this in an application I was working on I'd refactor it.
Scott posted the correct way to do this above (post of 26-Mar-2008 23:00&mdash;not marked as helpful/correct as this was before the forum had this feature): Clear cache using an On-Submit Application Process that is conditional on the <tt>:REQUEST</tt> value set by the relevant tab(s).
