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'}">-Erik

Some useful field validations are demonstrated in the orbeon.war Text Controls example. The Text Area for example, must have a value of “at least 10 characters.”
In my application, I’d like the user to enter anything he/she likes, as long as a value is supplied. If I add the constraint “string-length(.) > 0” then my rule will be enforced as expected.
I run into a problem when initially presenting the user with a blank form. An error message (i.e., the alert) is displayed, indicating the user has done something wrong. This is not the case, as they haven’t had a chance to provide any data.
What approach do you recommend, so that I can show the alert only when the user has committed an error?
(Again, just now beginning to get my arms around this stuff)
Thanks!
