Support for extended attributes incomplete?
Hi,
I am trying to extend the Tuscany xml processing with an extension to
process an extra attribute. I created a processor that implements
StAXAttributeProcessor, but when I try to use that, I get a
ClassCastException at BaseAssemblyProcessor:873. This code casts the
return value of my StAXAttributeProcessor to String ...
I am using Tuscany 1.4, but as far as I can see, this code is the same
in the 2.x SVN.
Can somebody please provide some details on the state of extended
attributes?
best regards
Wouter Horré

I found the problem. It was my fault. I did not extend the Extension
interface ...
Thanks for your help

How are you testing the write method ? If you adapt the
testReadWriteCompositeWithAttributeProcessor test [1] to use your own
processor, does the write method gets called ? Note that this method
is only supposed to be called when you try to write the composite back
to a file.

Hi,
Thanks for your clarification. I tried with 1.x from svn and I got it
working now.
One more question: the write method on my processor is never called. I
had to implement toString() on my model classes to get it working. Is
this intended behavior?
regards
Wouter

This has been fixed in the 1.x trunk code, and we now have a Extension
model object that wraps the extended attribute model. An example of a
processor is available in the assembly-xml test case. Most of this
code should be already merged/ported to 2.x as well.
