Answering my own question, with jQuery I found a way to display just a
single error message div for a list:string type field. I added this code to
the view:
{{if grid.update_form or grid.create_form:}}
{{#hide all list:string error divs but the first one, and move it
before the data}}
<script type="text/javascript">
$(document).ready(function() {
var f=['email','phone']; //list:strings
for (var i=0; i<f.length; i++) {
$('#person_'+f[i]+' .error_wrapper').each(function(i) {
if (i==0) $(this).siblings().first().before($(this));
else this.style.display='none';
});
}
});
</script>
{{pass}}
{{=grid}}
