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
