[Webware-discuss] exception recovery in WebKit

[Geoff T. <gta...@na...>]

I'm playing around with the WebKit Error example page.  The first time I
load it, I get an error page with the following traceback:

Traceback (innermost last):
    File "Application.py", line 291, in dispatchRequest
      self.serveURL(transaction)
    File "Application.py", line 347, in serveURL
      self.respond(transaction)
    File "Application.py", line 414, in respond
      transaction.servlet().respond(transaction)
    File "HTTPServlet.py", line 38, in respond
      method(self, trans)
    File "Page.py", line 35, in respondToGet
      self._respond(transaction)
    File "Page.py", line 54, in _respond
      self.writeHTML()
    File "Page.py", line 102, in writeHTML
      self.writeBody()
    File "Examples\Error.py", line 8, in writeBody
      import UnknownModule
  ImportError: No module named UnknownModule

This is fine; it's what I'd expect.  But after that, if I try to reload
the page, I get:

Traceback (innermost last):
    File "Application.py", line 291, in dispatchRequest
      self.serveURL(transaction)
    File "Application.py", line 346, in serveURL
      self.awake(transaction)
    File "Application.py", line 409, in awake
      transaction.servlet().awake(transaction)
  AttributeError: 'None' object has no attribute 'awake'

This exception persists every time I reload the page until I restart the
app server.

I assume this is a bug, not by design.  I'd prefer not to have to
restart the appserver in order to unwedge a page that has had an
exception.  I'll try to fix it myself, but since I don't know the code
well, any hints you can give me would be appreciated.
