Switching what page you link to on the fly?

Question

I am trying to see if this is possible. We have a report, and one of the columns has a link that goes to a detail page. No problem...except we don't always want to go to the detail page. We want to basically set it up conditionally so that in a certain condition, go to a report page. In all other conditions, go to the detail page. Right now it always goes to the detail page because I have no idea how to set this condition on a link.
Is this even possible? I can't find out how. If it isn't, is there any alternative that allows you to do something like this:
Detail page is loading
Check the condition in the load of the page to see if it is met
If so, switch so you go to the report page instead?
Any insight would be much appreciated.
Thx,

Karey,
Farhan's suggestion is that if you can test the condition during the generation of the main report, a decode statement can be used to construct the link so that the user is directed to different places based on the condition.
To do this you could create the link (or some portion of it) in the SQL for the report. When you look at the column attributed there is the section that allows you to create the link url such as:
f?p=&APP_ID.:136:#APP_SESSION#::::P136_PROD_ID:#PROD_ID#
Here we are going to page 136 and setting the P136_PROD_ID variable to the value in the PROD_ID column. If you could test for your condition in the SQL you could set a variable for the page id that you want to go to (say LINK_PAGE_ID could be the name). Then instead of where you see 136 in my sample url you'd put #LINK_PAGE_ID#.
To construct the sql you could test the condition with decode to supply the proper LINK_PAGE_ID value.
SELECT decode(test_value, 'ONE', 25, 35) AS link_page_id ..... etc. You could use CASE as well.
If you can't or don't want to check the condition until the user attempts to access the detail report then you could use a Branch that is conditional and executes On Load Before Header.
Hope this helps,
