Hi Fritz,
BTW, if you want to have your forms "on disk", so maybe you can edit them more easily by hand, you can place them under resources/forms, and configure Form Runner to use the resource persistence to read their form definition from there. I.e. if you app is gaga:
<property as="xs:string" name="oxf.fr.persistence.provider.gaga.*.form" value="resource"/>
And we do have some demo forms loaded that way:
