actionsequence classes: sometimes ignored for editfiles?

Hi:

I would like to add to two lines to /etc/passwd, but one must always be
the last in the list. To do this I elected to use a class on the
editfiles action sequence. However the last "edit" is always overlooked
by cfagent. To demonstrate, below I have an example cfagent.conf file
and output snippets. 

EXAMPLE:
<cfagent.conf>
control:

   any::

      actionsequence = (
         editfiles
         editfiles.Final
      )


editfiles:

  any::

      { /etc/passwd
              BeginGroupIfNoLineMatching "\+@netgroup"
                      GotoLastLine
                      InsertLine "+@netgroup"
              EndGroup
      }

  any.Final::

      { /etc/passwd
              GotoLastLine
              BeginGroupIfNoLineMatching "\+FINAL LINE"
                      DeleteLinesMatching "\+FINAL LINE"
                      Append "+FINAL LINE"
              EndGroup
      }

      { /etc/group
              GotoLastLine
              BeginGroupIfNoMatch "\+"
                      DeleteLinesMatching "\+"
                      Append "+"
              EndGroup
      }

=

<BEFORE cfagent run /etc/passwd is missing the two lines>

<RUN: % cfagent -fv ./cfagent.conf>
<snip cfagent output>

                             Final
Begin editing /etc/group
(Begin Group - skipping \+)
End editing /etc/group
.....................................................................

NOTE: The edit on the /etc/group file in the "Final" edit worked.
</snip>

<AFTER cfagent run /etc/passwd is missing the "Final" line>
<snip /etc/passwd>
+@netgroup
</snip>

I appreciate any insights.

Thanks,
