Nested Tag breakage?

           Summary: Nested Tag breakage?
           Product: Struts
           Version: Nightly Build
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Major
          Priority: Other
         Component: Custom Tags
        AssignedTo: struts-dev@jakarta.apache.org
        ReportedBy: sbb@penguinis.org


The attached JSP page, which is derived from examples/registration.jsp and 
designed to operate in the examples webapp, works properly in Struts 1.1b1.  
And until recently (I believe) in Struts nightly.  Now when it's executed, the 
following exception occurs [see below].  
<speculation>
   Changes in the form tag involving it's name attribute (which now seems to be
   null if getName() is invoked a form tag instance, instead of the name 
   that was inherited in the action mapping as it was in 1.1b1) have caused
   the problem in the nested tag library in the nightly build.  Given there 
   not much in the way of regression test for the nested tag library, at
   the moment, it's easy to see how this kind of breakage might have passed
   unnnoticed.
</speculation>

[I'm marking the severity as major because this will potentially affect many 
users of the nested tab library.]
