Re: [Chiba-users] Unable to render XForm with linked schema.

[Joern T. <joe...@ch...>]

Hello Mickael,

have you tried to turn on logging in log4j.xml? Please set org.chiba.... 
to 'DEBUG'. Hope this reveals a bit more info.

I don't find an obvious problem (assuming your form is in the same 
directory as the schema) with your form except maybe the space in front 
of the
schema=" simple-form-iinstance.xsd"

but i assume that's an editing glitch.

Please keep me informed if you find something more or if your problem 
persists.
