           Summary: [PATCH, CFORMS] Nested repeaters broken in AJAX
           Product: Cocoon 2
           Version: Current SVN 2.2
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: CocoonForms
        AssignedTo: dev@cocoon.apache.org
        ReportedBy: cocoon@lojjic.net


This issue was originally described on the dev mailing list:
http://marc.theaimsgroup.com/?t=112740966900004&r=1&w=2

There is a problem with repeaters (and other container widgets?) in CForms when
AJAX mode is turned on, that causes an error when a repeater-within-a-repeater
is updated.  After more investigation I found a couple underlying problems that
were causing this:

The first problem was that JXMacrosHelper.getRepeater() throws an error when the
.getWidget() method did not add the widget to the stack, as is often the case
with AJAX updates.

The second problem was that there was a bug in Form.addWidgetUpdate() that was
stopping ancestor widgets above the parent widget from getting added to the
childUpdatedWidgets set.  This meant that if a widget more than one level deep
was updated then its top-level container would not be updated.

Patch forthcoming.
