[Building Sakai] portalscripts.js causing error on login page in 2.7.x

[csev]

Bryan, 

Make sure to file a JIRA with a patch and assign it to me or Gonzalo when this gets figured out to make sure it gets fixed in trunk and for 2.8.

I think that the scripts you are speaking of are the "check if I am about to be logged" out scripts  Interestingly in 2.7 this is off by default but the scripts run anyways - mostly to figure out that they are off :)  Unless you use the feature a quick workaround is to remove the bit of JQuery in portalscripts that fires these up.

In Sakai 2.8, things work differently.  I had the portal include a bit of data in the page that indicates if you are logged in or not so these scripts don't make any additional requests as they have the data they need.   I will test this in 2.8 to make sure it works in 2.8 with the new 2.8 approach.

I like the gateway site like feature so we need to make sure everything works.

Thanks.

/Chuck

This div exists when a user is not logged in because of the above property that we are using. So some functions are being called that shouldn't be called unless you are logged in.
