serializer kicking in before transformer finished

[Jorg Heymans <jh...@domek.be>]

Hi,

In my custom transformer (extends AbstractDOMTransformer implements 
LogEnabled, Cacheable) I have the following :

    public void endDocument() throws SAXException {
        super.endDocument(); // required
        try {
            helper.endDocument(); // this call potentially takes a few 
seconds
        } catch (Exception e) {
            throw new SAXException(e);
        }       
    }

sitemap snip:
<...
        <map:transform type="custom"/>
        <map:serialize type="blob"/>
..>

The result of this is that the blob-serializer seems to kick in before 
the custom transformer is fully finished. The output i'm getting is the 
output as if the transformation never occured. The logfile entries 
indicate the same, blob logentries appear in between my transformer entries.

Can i get around this? Is this expected behaviour ?

So,

this all depends on the *order* of events which wasn't clear to me
For a transformer following methods are called in sequence

startDocument()
.. all the SAX event methods here
endDocument()
notify()
transform()

and then it moves to the next pipeline component.

WIki entry 
http://wiki.cocoondev.org/Edit.jsp?page=ImplementingTransformers more or 
less describes this as well.
