Hi again!
So, I have become desperate :-) and started poking around in the Tuscany
source code.
The NullPointerException that I experienced earlier is caused by a
component type property having a null XSD element. I modified the code,
as below, to avoid the NullPointerException.
[code]
...
// check that the types specified in the component type and
component property match
if (componentProperty.getXSDElement() != null
&& !componentProperty.getXSDElement().equals(
componentTypeProperty.getXSDElement()))
{
// MY MODIFICATION HERE.
String theCompTypePropXSDElem = "[not available]";
if (componentTypeProperty
.getXSDElement() != null)
{
theCompTypePropXSDElem =
componentTypeProperty.getXSDElement().toString();
}
Monitor.error(monitor, this, Messages.ASSEMBLY_VALIDATION,
"PropertXSDElementsDontMatch", component.getName(),
componentProperty.getName(), componentProperty
.getXSDElement().toString(),
theCompTypePropXSDElem);
}
...
[/code]
With this modification in place, I now receive the following messages in
the log:

The question is: Why is the component type property null?
Isn't the property type supposed to be inferred from the field annotated
by the @Property annotation or have I misunderstood?
Best wishes,
Ivan
