Description Thorsten Schenkel CLA 2011-10-26 05:45:31 EDT 
If the URL of the BrowserRidget is empty (null or empty string ""), BrowserRidget.updateUIControl doesn't work, because the follwoing exception is thrown:

java.lang.StringIndexOutOfBoundsException: String index out of range: 0

This error is not reproducible with Windows (no WebKit).

I could only reproduce this on Ubuntu + Webkit.
Passing null or an empty String to the Browser.setUrl(...) methods is not valid since it is not a valid URL (the constructor new URL(string) will fail. If a blank page should be shown in the browser widget, the String to pass is "about:blank". This works with IE, Mozilla and Webkit.
