Hi Raymond,
I created an issue on JIRA and I really appreciate for you help!
One more question: why "databinding.dom" included in
/core/databinding.scdl
is implemented using SimpleDataBinding instead of DOMDataBinding:
<component name="databinding.dom">
<system:implementation.system
class="org.apache.tuscany.core.databinding.impl.SimpleDataBinding" />
<property name="className">org.w3c.dom.Node</property>
</component>
If I want to use DOMDataBinding, I have to override the default
definition?
Thanks!
Li

Hi, Li.
Thank you for trying it out. Please see my comments below.

Sounds good.

I'll check the code. Is it possible that you open a JIRA and attach your
test case there? I would be glad to make it work.

It's work in progress. We're planning to have a consistent SCDL
extensions
at the assembly level to deal with databindings.

Good point. That was what I have been thinking of. We can try to use the
physical type for the DataType as the JAXB class as the last resort. I'll
add some code to do so and see how it goes. But please keep in mind,
sometimes it's not possible to detect it if the parameter is directly
typed
as a JAXB class.
