My company still has many pre-8.5 servers. You can use dojo on almost any version of Domino. You can use dojo in your legacy web forms too. Dojo is not the best solution for every need but it is pretty nice, and sometimes the best!

This database has several dojo elements exampled. You will see what is needed to incorporate dojo into your code, what needs to be setup in your 'HTML Head Content' and some different ways to use dojo (pass thru html or within field properties). You will see some dojo limitations and advantages. I took this opportunity to also show the user a couple different ways to design web elements.

This database will show you the things I learned and hopefully, save you some time in your exploration.  This is not an application. This is a simple database with one view and one form with dojo type fields exampled on a form.

This database example presumes your firewall allows the google javascript api to pass. I will be uploading additional instructions explaining how to use dojo when your firewall rules prevent this example from working.

This database is an expansion of a database I found at Lotusphere2008 'SpeedGeeking' session. I have changed the name to prevent users from confusing this with the original not to take any credit for the fine work done by Scott Good or Henry Newberry.
