Trying to do it the seam way... I use this in my edit.xhtml
<s:div styleClass="edit_template_error_area" rendered="#{!empty facesContext.maximumSeverity}">
<s:message styleClass="error" />
</s:div>
This is great in that it does not render whenever I have no errors (so my lines are not padded out with blank lines).
If, however, one line is error then this fires for all lines.
Can I see if a certain field is in error as apposed to ANY field in error.
I see that this decorate tag auto-magically knows which field is in error with as it renders the error message for the right field...
Cheers.
