Hi Venkatesh, my understanding is that the AdvancedUI is a global business rule which just provides access as a user preference to a series of "Insert", "Insert and Stay" and "Save" UI actions based on the system property which you mention: glide.ui.advanced. But... that's it!

This AdvancedUI business rule was created on 2008-02-22 20:44:24, so i will suspect no necessarily we should be expecting something new out of it. (or at least for now until someone uses this property for other elements/things in mind ).

Here goes other similar answer to this same question:

UI Actions - isAdvancedUI

Thanks,
