AbstractDOMTransformer

[Michael Wechner <mi...@wyona.org>]

Hi

Is anybody using the class

org.apache.cocoon.transformation.AbstractDOMTransformer

successfully?

It seems to me that since Cocoon has moved from DOM level 1 to level 2
it doesn't work anymore.

Thanks

Michael

Sorry, my fault. Should be fixed now, could you try again (on
cocoon-2.1, not yet applied on cocoon-2.0) and let me know if it's all
ok now? Thanks

No, unfortunately I still receive an exception (I tried the new 
cocoon-2.1 (co cocoon-2.1) and the old xml-cocoon2 module)

that helped. I patched my local version of AbstractDOMTransformer:

public void notify(...

     DOMStreamer s = new DOMStreamer(...
     s.setNormalizeNamespaces(false);
     ...


If I will find some time, then I will take a closer look at 
AbstractDOMTransformer and DOMBuilder. I think the bug is at building 
the Document from SAX.

Thanks a lot for your help

I patched DOMStreamer this morning so that it correctly handles 
non-document nodes, but introduced a bug that well could affect 
AbstractDOMTransformer :-/
I fixed it just now. Could you please cross-check (in HEAD) ?
