In actions fired with separate urls perhaps?

Hum ...
In fact the transaction id is the file url.
IMHO endDocument is not called if an exeption occure in pipeline.
See the transformer in attachment.
Comment are very welcome ...

RE: Free for use: SaveFilesTransformer
> Can I ask why we need a simplified SourceWritingTransformer? Ofcourse you can: you just did.. :-) No, I don't think a simplified one is needed, but it is the second use case that is most interesting. Perhaps I should have said that it is *another* SourceWritingTransformer.. :-P Kind regards, Geert Drs. G.P.H.
