What is the expected output? What do you see instead? The unit test should 
execute without error.

What version of the product are you using? On what operating system? Using 
gwt-test-utils 0.38 on Windows XP.

Please provide any additional information below. This error did not occur when 
I used the 0.35 version of gwt-test-utils. This error does not occur when using 
Google's gwt test framework.

Hi,

ListBox <ui:item> element are handled starting 0.39. I've updated your 
UiBinderBug project  gwt-test-utils dependency and the 
GwtTestBuggedViewGwt.testAsWidgetReturnsSelf() passed.

Could you please update to gwt-test-utils-0.39.jar and give me some feedback ?

Tested using the 0.39 jar, and my project's failed test cases in my project are 
now working.
