[Building Sakai] SAK-25503 - Remove iframes from Sakai's Portal markup

[Charles Severance]

I created a JIRA to track progress to remove the iframes from the portal's markup. 

https://jira.sakaiproject.org/browse/SAK-25503

This may sound daunting, but it really means using the same technique of tool content inlining from the PDA portal. Since we have been using and debugging the PDA portal for quite some time no.

The work in the main portal has already started in SAK-25494 and if you want to see it in action, set the following property in a trunk checkout:

portal.inline.experimental=true

If you set this, you will notice that left-nav tool switching URLs switch from

http://localhost:8080/portal/site/963b28be-1d37-4d6c-b876-1f177784466f/page/0dedb05e-219d-4d0b-b9bc-72ca3e1cd750

to 

http://localhost:8080/portal/site/963b28be-1d37-4d6c-b876-1f177784466f/tool/eb9909db-71ef-4dcf-9fbb-daf46b70adb2/overview.jsf

"page" becomes "tool"  and the last parameter is tool id instead of page id.  Also the URL starts to grow with the GET parameters the tool is putting on.

Nearly all the tools will work immediately.  A few will be confused - for example if you do Site Info and Page Order - you will see the tools losing track of where they are as they forward back and forth.   Of course this can be fixed.   But there will be lots of little issues that need to be found and fixed before this can be used across Sakai.

But it is nice to be able to use the back button :)

Happy holidays and comments welcome.
