             Summary: Initial view for sofa unaware components not automatically created
                 Key: UIMA-2419
                 URL: https://issues.apache.org/jira/browse/UIMA-2419
             Project: UIMA
          Issue Type: Bug
          Components: Core Java Framework
            Reporter: Richard Eckart de Castilho

When running a sofa-unaware component in an aggregate analysis engine, the initial view for the component
to operate on is not automatically created if it does not exist. This causes a CASRuntimeException, here
"No sofaFS with name A found.".

I'd consider this a bug, because a sofa-unaware component cannot be expected to create a view itself. If the
sofa-unaware component is the first one in an aggregate, e.g. acting as a reader, then there is also no
other component to create the view before.

If the initial view of a component it is mapped to does not exist, it should be the task of the UIMA framework to
create this view.
