Setting current tab

Question

I have a page which holds functionality for two different tabs. The current tab is defined by a combination of page id and the value of an application level item.
How can I programmatically set the current tab via an onload after header process? Do I set wwv_flow.g_current_tab or wwv_flow.g_step_tab_set?

Answer 1

you could do the following:
use the array g_tab_name to retrieve the order in which the tab parameters are stored in the array variables.
ie
for i in 1..g_tab_name.count loop
:PX_TABS := ';' || g_tab_name(i);
end loop;
then you could on the fly set the tab current for pages value for the required tab depending on your application level item:
in an application level on load before header process do:
if app_item = 'X' then
wwv_flow.g_tab_also_current_for_pages(1) := :APP_PAGE_ID;
elsif app_item = 'Y' then
wwv_flow.g_tab_also_current_for_pages(2) := :APP_PAGE_ID;
end if;
(Set the condition on this process to only fire for pages which can be current for multiple tabs)
You will need to ensure that the tabs exist on every page you wish them to appear (other wise the process will fail). This can be done by setting the 'also current for pages' option for every page in the tab and then saving. The tabset will now appear on every page...
You now delete the page numbers (from the 'also current for pages' option) which can be current for more than one tab and save the tab again. The pages current for multiple tabs will now have the tabset appear in the page definition but will not be current for any tab. The required tab will now be set to be current at runtime for these pages by the above process.
hope the above makes sense and was what you required ;-)
