Thanks Alex,
It is working now.
I am trying to grasp the basic concepts of form processing with the OXF
platform. I am very familiar with Struts so I will use that
understanding as a base point for explaining my uncertainties.
As I see it the controller acts much like the Struts controller when
handling a request for the /credit-card example below:
<page path-info="/credit-card"
xforms="oxf:/credit-card/xform-model.xml"
model="oxf:/credit-card/model.xpl"
view="oxf:/credit-card/xform-view.xml"/>
It automatically instantiates an xforms-instance "bean"? as defined in
the xform-model.xml, creates the xform view to be sent to the browser by
processing the xform-view.xml and maps the form to the model(model.xpl)
for processing. When the form is submitted the OXF controller
automatically populates the xforms-instance and makes this instance
available for further processing as defined in the model pipeline.
In your corrections of my buggy example in the model.xpl you simply pass
the output to the console using the processor below:
<p:param type="input" name="instance"/>
<p:processor uri="oxf/processor/null-serializer">
<p:input name="data" href="#instance" debug="instance"/>
</p:processor>
So this is taking the xforms-instance generated by the forms submit and
creating a "null-serializer" to process the input that simply dumps it
to the console. Before I continue with my explanation resulting in my
current problem I would like to know if you could point me to the
documentation on the available processor factories that outlines how to
reference them the parameters that they take and what their
functionality is. I read the User Guide and the "Processor Reference"
but still feel I need more.
With the current example I thought I could append another processor to
transform the xforms-instance document to be viewed by the browser. What
I did is this:
<p:param type="input" name="instance"/>
<p:param type="output" name="result"/>
<p:processor uri="oxf/processor/null-serializer">
<p:input name="data" href="#instance" debug="instance"/>
</p:processor>
<p:processor uri="oxf/processor/xslt"
xmlns:p="http://www.orbeon.com/oxf/pipeline";>
<p:input name="config" href="stylesheet.xsl"/>
<p:input name="data" href="#instance"/>
<p:output name="data" ref="result"/>
</p:processor>
Is this right, content is dumped to the console but the page does not
change in the browser? If I have been correct so far this is where I am
lost.
Also in Struts form processing I always build a EditXXXFormAction and a
SaveXXXFormAction. With OXF does every form "Action Event" need to be
defined in a editModel.xpl and saveModel.xpl? Once I figure out why I
don't get output to the browser I want to edit an XML Instance and load
the xform with the instance data. How would that be achieved?
Can anyone point me to a xforms tag lib documentation?
Many thanks,
Greg
