Hi,
I wonder how to implement a generic AE that is able to create a new CAS
and copies a given view to a specified view of the new CAS. The new CAS
then should be serialized.
What I tried is here:
https://svn.apache.org/repos/asf/uima/sandbox/ruta/trunk/ruta-core/src/main/java/org/apache/uima/ruta/engine/ViewWriter.java
When I call this AE within Ruta without mapping, then
getContext().getEmptyCas(CAS.class) returns a CAS without additional
types and CasCopier removes all annotations (due to lenient). With
mapping, it complains that the sofaFS specified by the parameter cannot
be found.
The getContext().getEmptyCas(CAS.class) is defined to get a empty CAS which has
the same type system as the current one. The getContext() should return a
UimaContext object. A Cas definition is located from that via the UimaContext's
getResourceManger() call , which should return the overall (for the pipeline)
ResourceManager. That, in turn, has a getCasManager() which should be pointing
to info that includes the Type System info of the CAS that's flowing in the
pipeline.
So I don't know why all the annotations are being removed. You shouldn't need
the lenient option - the type system should be the same, I think.
If you can post sufficient instructions to enable me to run (from trunk), or
have a driver/ testcase, I can try and see what's going on...
I will try to provide one tomorrow.

I tried a few things without success. The next thing would be to provide
a parameter with the location of a descriptor for creating a separate
CAS and completely avoiding the CAS multiplier functionality...
Any ideas?
