rev 49353

The changes for RadioButton checked in at r 49350 (Jenkins Build #2131) are causing a regression in emporium sample application; this is still an issue at Jenkins Build #2147.

Browser console errors occur in all browsers if navigating from "Auction List" tab to "Settings" (containing radioButtons), and back to "Auction List". Also, the auction items fail to render on return to the "Auction List" tab, until the page is reloaded (F5).

Chrome:

Tested emporium application with ICEfaces 4 trunk r49461 using Tomcat 8, FF 47, IE 11, Chrome 53, mojarra and myfaces libs. I was no longer able to reproduce the regression issues as listed in the previous comment.

resolved with work on ICE-11155
