An
Error Input Stream can only catch errors thrown within the same
Parallel Region. Otherwise the error is caught by the region's default error handler. In the above example, the Module element is set with "
Run this component in a parallel region" property enabled, which is why it has the circle overlay on its tile.
Add an
Error Input Stream within the concurrent region to catch exceptions thrown within that region. Note that elements other than Error Output Streams may also throw errors which will also be caught by the available
Error Input Stream.
