Using schema for validation (orbeon3 beta3)

Hi everybody, thanks allot for help!

Some posts ago Eric sends a new hello4 example (xforms ng). I get it working with orbeon 3 beta 3 without any problems. ;-)
I added an attribute age to initial-instance.xml. Ok.
Then I wrote a schema.xsd with <element name="age" type="integer"/> for validation.
I have tried to use this schema with <xforms:model schema="oxf:/example/schema.xsd">.
It seems to work. There comes up a mark until I write an integer to the input field of age.
But now the "next" button is not working anymore.

Please, can anybody show an easy example how to use schema for validation with xforms ng?

Re: Using schema for validation (orbeon3 beta3)

Another Question: Is there a better way for validation as schema?

This is the source for the example

initial-instance.xml
<myform>
<action />
<first-name />
<age />
</myform>
------------------------------------------------
schema.xsd
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="myform">
<xs:complexType>
<xs:sequence>
<xs:element
name="action"
type="xs:string" />
<xs:element
name="first-name"
type="xs:string" />
<xs:element
name="age"
type="xs:int" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

The BizDoc NG example uses XML schema for validation. I recommend you
look at that.

It may be more lightweight and portable for now to use contraint or type
binds, e.g. things like:

<xforms:bind nodeset="my-element" type="xs:positiveInteger"/>

or:

<xforms:bind nodeset="my-element" constraint="normalize-space(.) > 0"/>
