Markus Joschko commented on SLING-2156:
---------------------------------------
I very much like the broader approach as I have another use case in mind for
which this kind of postresponse creator can be handy:
In my application there is a validating postprocessor that inspects the
modifications done within an operation. If it finds something "wrong" it only
can throw an exception to prevent the saving of the node.
The resulting error page is not particular catchy as the error message is a bit
hidden. With the postresponse creator it could be presented a lot better to the
client.

> The error handling mechanism described here [0] doesn't seem to apply also to
> POST operations.
> If an error occurs while posting a resource to repository (e.g.
> avax.jcr.nodetype.ConstraintViolationException: no matching property
> definition found for) the HtmlResponse.html template is rendered.
> This can also represent a security issue since information as
> REFERRER/technology stack are shown.
> IMHO this page should be at least configurable (if the mechanism in [0]
> doesn't suite here).
