[Zope] Zope 2.8.4 external methods do not autorefresh

[Dennis Allison]

test framework:

<dtml-var standard_html_header>
<dtml-var expr="eproc()">
<dtml-var standard_html_footer>

Setup an external method

def eproc( self ):
        return 'hello world'

and run the test method.  It prints

hello world

Now, change the test method
  
def eproc( self ):
        return 'hello world too'

and run the test method.  It prints

hello world

which is a deviation from the usual Zope2 behavior.  

To adopt the code for the modified method the external method needs 
to be resaved.

Is this a bug or a feature?
