To reproduce:

- Download Liferay 4.3.0-RC1 from here and install:
http://www.liferay.com/web/guest/downloads/liferay_enterprise_portal/4_3_0rc1

- Download the sample-icefaces-sun-portlet.war from here and drop it in $HOME/liferay/deploy (hot deploy folder):
http://www.liferay.com/web/guest/downloads/samples

- Start the portal

- Start FireFox (as it has better error console reporting for JavaScript)

- Using FireFox, visit http://localhost:8080 and login as test@liferay.com with password test

- Add a new portal page named "ICEfaces"

- Add the Sample ICEfaces (Sun RI) Portlet from the "Add Content" option

- Click on "Page Settings" option

- On the left hand side, click on the main/root "Joe Bloggs" tree node

- On the right hand side, click on "Look and Feel"

- Click on the "Desktop" theme

Note that at this point, all portal pages should take on the portal theme

- Note that on the "ICEfaces" page, when the mouse is positioned in the hard blue titlebar of the ICEfaces portlet, JavaScript errors are reported by the FireFox error console:

"item.fn" is not a function in http://localhost:8080/html/js/liferay/animate.js

Now, I understand that the error is occurring in a Liferay JavaScript file, and if y'all think that this is something that the Liferay folks should fix, then by all means say so.

Thanks,

Neil
