Subject [jira] Commented: (COCOON-1906) [PATCH] simple-xml binding does not work with non file sources

Jean-Baptiste Quenot commented on COCOON-1906:
----------------------------------------------

Hi Lars,

Thanks for your patch, however I don't think it's a good idea to add toSAX(SitemapSource,
ContentHandler), because SitemapSource is an implementation of Source.  If we added this method,
we would also need to add toSAX(XMLDBSource, ContentHandler) as you mention xmldb, and every
possible implementation of Source.  That doesn't make sense.

Can you come up with a better solution?

> The cocoon forms flowscript API comes with a helper method form.loadXML, that retrieves
data from an xml document. The current implementation however does not work with documents
that are referenced not as files, but as SitemapSources, e.g. via the cocoon:/ or xmldb://
pseudo-protocol. In this case the Rhino engine is unable to resolve the ambiguity between
two method signatures:
> org.mozilla.javascript.EvaluatorException: "resource://org/apache/cocoon/forms/flow/javascript/Form.js",
line 287: The choice of Java constructor toSAX matching JavaScript argument types (org.apache.cocoon.components.source.impl.SitemapSource,org.apache.cocoon.forms.util.XMLAdapter)
is ambiguous; candidate constructors are:
> void toSAX(org.apache.excalibur.xml.sax.XMLizable,org.xml.sax.ContentHandler)
> void toSAX(org.apache.excalibur.source.Source,org.xml.sax.ContentHandler)
