Field validation

I have a form that, when it is submitted, I use a custom processor to write the form out to a special folder.

I use a trigger to activate this custom processor (example code below).

The problem I am running into is that no field validation occurs. My users can just press the button and away the form goes. I wanted to find out if there is some kind of validation call I can make so that I don't attempt to save the form until all my enforced fields are filled in correctly.

Can anyone shed some light on this? I am using ops 3 beta4.

Example code:


<xhtml:p>
<xforms:trigger>
<xforms:label>Save data</xforms:label>
<xforms:action ev:event="DOMActivate">
<xforms:send submission="save-form"/>
<xforms: toggle case="saved"/>
</xforms:action>
</xforms:trigger>
</xforms:p>


<xforms:submission id="save-form" method="post" action="/services/save-form" replace="instance"/>

Thanks.

- Dan

Re: Field validation

I posted the same question a while ago. There is an example (bizdoc I
think) that shows how to augument your page-flow.xml to make sure all
fields are populated with valid data before submitting. The logic is
based on checking values of the xxforms:valid and xxforms:relevant
attributes. Something along these lines:

<action when="(<your submission params> and
/your/form-model//*[@xxforms:valid = 'false' and
not(ancestor-or-self::*[@xxforms:relevant = 'false'])]">

Dan,

If your XForms instance is not valid (and also if some fields are
required but empty), it won't be sumitted, period! So there is nothing
particular to do provided you either use an XML schema or xforms:bind
elements to validate your instance in your XForms model. This is quite
well illustrated by the BizDoc NG example.

Alex,

Dan's questions is a little different because, based on your example
below, you appear to be using the Classic XForms engine, which left to
user code in the page flow the decision to handle validity. With XForms
NG, as per the XForms spec, an invalid instance will simply not be
submitted at all by the XForms engine.
