RFE: method attribute on page element

I had an idea for Orbeon that I'd like to present to you. I looked into
doing it myself, but ran into some setbacks, so possibly you could get
to it before I could.

Basically, what I would like to see is support for a @method attribute
on <page> elements in the PFC. If a page element has a method attribute,
then that element is selected only if the path matches and the method
that generated the request is one of the comma-separated values in the
attribute. Omitting the method attribute would cause the element to be
selected for any method. (thus no need to change existing code)

Having this capability would make it much easier to build fully RESTful
applications using Orbeon Forms. Currently, my workaround to this is to
handle flow over to an XPL that reads from the request-generator, which
in turn calls another PFC processor based on the value of the method.
With this in place, I would be able to collapse all of that into a
single file. (not to mention the considerable performance benefits)

Like I said, I'm still looking into ways to do this on my end, but I'm
sure you would be able to implement it way faster than I would. (being
/much/ more familiar with the code and all)

In the mean time, how do I modify the validation of PFC files? Editing
org/orbeon/oxf/xml/schemas/page-flow-controller.xsd didn't seem to do
the trick. I tried re-starting the server, do I have to re-compile? Or
am I just looking in the wrong spot?

Daniel,

This is a good suggestion. One may also want to match on request
parameters, than just on the request path. I can't guarantee if or when
we will do this, so if you manage to do it and contribute the changes
that would be even better. After all, Orbeon Forms is open source ;-)

It seems that we produce during build a file called:

   page-flow-controller-runtime.xsd

This is the one used at runtime by the PFC. So you should either run the
ant target "transform", or manually modify
page-flow-controller-runtime.xsd instead of page-flow-controller.xsd.

Hopefully this helps.

-Erik
