Subject: Re: [orbeon-user] constraints, alerts
Brian,
(Pasted from an earlier reply on the same subject:)
I recommend you look at the BizDoc example, which does exactly this. We
add to the XForms instance a /form/show-errors element, which we set to
true in the Page Flow if errors are found when trying to save. Then, in
the view, we set the attribute like this:
<xforms:group ref="/form"
xxforms:show-errors="{/form/show-errors = 'true'}">
