Thanks Hank and Ryan I will give that a go.
Michael, You don't declare any outputs to your processor. As I understand, if you do not reference an output, then the "lazy evaluation" will not invoke your processor. If the side effect of running the processor is the goal (and not any output it produces) then I think you nevertheless need to produce something and use it as input to another processor or refer to a data output. --Hank On Dec 1, 2008, at 6:52 PM, Michael Watson wrote: > Hi all, > > I am trying to get a custom processor working however I'm not > having much luck at the moment.

You
could also look at the code for the null serializer processor for an example of
a processor with no outputs - in fact you could first experiment using that
processor to make sure you get your page flow/model/view configuration correct
before putting your own processor in.

Thanks Steve, I will give this a go too.

Hi Ryan,

I tried the things suggested but still don't seem to be having any luck. I changed my Processor to return a value, configured it like this: page-flow.xml: <config xmlns="http://www.orbeon.com/oxf/controller"> <page path-info="/my-bookcast/" view="view.xhtml"/> <page path-info="/my-bookcast/add" model="service-save.xpl"/> <epilogue url="oxf:/config/epilogue.xpl"/> </config> I also tried: <page path-info="/my-bookcast/add" view="service-save.xpl"/> service-save.xpl: <p:config xmlns:p="http://www.orbeon.com/oxf/pipeline" xmlns:my="http://watsmi.org/ops/processors" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:oxf="http://www.orbeon.com/oxf/processors"> <p:param type="input" name="instance"/> <p:param type="output" name="ignored"/> <p:processor name="my:processor"> <p:input name="data" href="#instance"/> <p:output name="nothing" href="#ignored"/> </p:processor> </p:config> However the processor still doesn't seem to get invoked. Any further ideas about what I am doing wrong or perhaps an example I could play with? As an aside, what should the behaviour be if the xpl file referenced in page-flow.xml doesn't exist? Even if I set it up to reference a non-existent xpl file I don't get any errors which makes me suspect that the xpl is never getting invoked... if I manually browse to the url I have set up on page-flow.xml I get the following error (pointing at the xpl file that does exist): Error unexpected attribute "href"(schema: http://www.orbeon.com/oxf/pipeline) Which is pointing to this line: <p:output name="nothing" href="#ignored"/> However I am not sure if that is just because there is no model at that point?
