First, Is there a way to make such as formular without explicitly check every field validation in page flow ?
And, is it possible to display error messages only when data have been sent at least once, and not on first display of the form, without explicit declaration in constraint ?
Then, when there is a validation constraint on an input field, the corresponding xforms instance data field is auto-populated with an "xxforms:valid" attribute. The problem is that it seems that I cannot access this attribute in page flow in order to ensure validity of data, even if I declare xxforms namespace I get an exception : "Namespace prefix 'xxforms' has not been declared"
I'm using Orbeon 2.6 on tomcat 5.0.28
