ProxyPass & ErrorDocument

Unless I misunderstand something, I found a problem with ProxyPass 
behaviour:
with the config below, I expect, when the back-end server does not 
answer (status 502), to receive my custom HTML page.
But it doesn't - the exception (ProxyPass  "/local"  !) is ignored.

  ErrorDocument 502 /local/unavailable.html
  ProxyPass  "/local"  !
<Location />
   ProxyPass  "http://..."
</Location>


Note that, when using <Location /path>, the correct custom page is 
displayed.

Is this indeed a bug?
Any work-around?

Thanks,

Nick

I don't use exactly that construct, but this works perfectly

ProxyPass /internal !
ProxyPass /sso !
ProxyPass / http://backend/
