Try it with *this* version of the serializer in Cocoon. We need to eliminate that its not just a missing element. The original serializer supported Gnumeric tag language as used in Gnumeric .7. The current serializer supports something aken to 1.03 or so (it should probably work with newer versions but I haven't installed one yet to verify).
Do note, that until I relized there was a demand, the original sourceforge version of the serializer was intended to be installed in Cocoon as well. We're working on a new project called Morphos for independant use. The serializer is being refactored there (in jakarta-commons). -Andy PLISSON S�bastien (DSIT-XS/I) wrote: >The same document parsed with an old version of POI (containing the >serializer, >before it was integrated in cocoon). > > >-----Message d'origine----- >De : Andrew C.
