custom transformer

Hi,

I'm writing a custom transformer, extending the AbstractDOMTransformer. Is there a way to throw an exception from this transformer so that the error handling pipeline of the sitemap is 'activated' ? (the transform method signature does not throw an exception). Or is the error handling from the sitemap only meant for SAXExceptions ?

I'm using Cocoon2.0.4

thanks !
Geert

In the case of AbstractDOMTransformer, transform() doesn't declare any 
exceptions (which it should IMO), so you might have to rewrite the 
notify() method in your transformer so that your transformation 
operation can throw exceptions.

Any checked exception in setup or any of the ContentHandler methods should activate 
the error pipline. If you can't throw a ProcessingException in setup, wrap a SAXException
around your real exception.
