Re: Problems with schema2XForms converter tool: msg#00003

Hi,

It seems there's a bug in castor: it doesn't return a simple type for attributes where none is specified in the schema (in the XMLSchema spec it is specified that xs:anySimpleType should be used when none is provided).
I solved the problem in the CVS version of chiba, by setting the type to string when there is no type.
So now it should work with the CVS version.

Regards,

Sophie

Subject: [Chiba-developer] Problems with schema2XForms converter tool

Hi,

I'm evaluating the schema2XForms tool and I'm having
trouble with an example I have built, inspired by the
first example given in the "XForms essentials" draft
available here
http://dubinko.info/writing/xforms/book.html#id2800591
(see the following files for details).

I would like to know the limitations of this tool
(among others, does it support schemas involving
multiple namespaces ?)
What should I consider its status to be (alpha, beta,
etc.) ?

The schema and instance I'm using are valid and
"rather" simple, but I'm getting this error :

java.lang.NullPointerException

The following files ubl-instance.xml and ubl_po.xsd
are valid, according to XMLSpy validation.

Thank you in advance if someone can help.
