Hi all,
So I am trying to parameterize a sitemap that I am using with forms and running into
an interesting situation. I don't know enough about components and actions yet, but
this may be a bug in AbstractXMLFormAction. (I've changed the names in the code
below, but it's just Heidi's example...)
Sitemap snippet:
<map:match pattern="bill2forms/*.html">
<map:act type="HowtoWizardAction">
<!-- XMLForm parameters for the HowtoWizardAction -->
<map:parameter name="xmlform-validator-schema-ns"
value="http://www.ascc.net/xml/schematron"/>
<map:parameter name="xmlform-validator-schema"
value="forms/{1}/xmlform-sch-report.xml"/>
<map:parameter name="xmlform-id" value="form-{1}"/>
<map:parameter name="xmlform-scope" value="session"/>
<map:parameter name="xmlform-model"
value="com.bill2.site.xmlform.HowtoBean"/>
<!-- Content transformation logic -->
<map:generate src="forms/{../1}/{page}.xml"/>
<map:transform type="xmlform" label="xml"/>
<map:transform src="forms/{../1}/wizard2html.xsl"/>
<map:transform
src="context://stylesheets/xmlform/xmlform2html.xsl"/>
<map:serialize type="html"/>
</map:act>
</map:match>
If you look at the parameterization, all of the <map:parameters> use "{1}", but all
the other components are sent "{../1}". This is what it takes to get the sitemap
interpreter to be happy and put the start page on the screen. But when it comes to
clicking on the "Start" link on the first form page, the following exception is
generated:
org.apache.avalon.framework.CascadingRuntimeException: Failed loading validating
schema
at
org.apache.cocoon.acting.AbstractXMLFormAction.getFormValidator(AbstractXMLFormAction.java:365)

org.apache.cocoon.acting.AbstractXMLFormAction.getForm(AbstractXMLFormAction.java:179)

org.apache.cocoon.acting.AbstractXMLFormAction.act(AbstractXMLFormAction.java:202)
at
org.apache.cocoon.components.treeprocessor.sitemap.ActTypeNode.invoke(ActTypeNode.java:133)
I wouldn't mind submitting the patch, but I'm not confident enough yet of the
semantics of parameterization to know if I am doing the right thing. I presume that
the problem is in AbstractXMLFormAction by the fact that the other components weren't
changed, but that kind of hunch is not a very responsible manner in which to submit a
patch...
If it takes longer to describe than it does to fix, I can wait for the next bug in
order to put some work in. But I do want to learn about the semantics of
parameterization more, and I only really know about {../*} from a post that Vadim made
a long time back. Is there a full explanation of this anywhere? (RTFM?)
best,
-b
