I'm tring to customize error rendering in my form according to this
example:
http://www.symfony-project.org/forms/1_4/en/03-Forms-for-web-Designers#chapter_03_sub_fine_grained_customization_of_error_messages
Here is my code:
if ($this['message']->hasError()) {
$error_msg = '<ul>';
foreach ($this['message']->getError() as $error) $error_msg .=
"<li>$error</li>";
$error_msg .= '</ul>';
}
return $error_msg;
but when `$this['message']` has error this code returns `'<ul></ul>'`
so it seems `foreach ($this['message']->getError() as $error)` causes
no iterations
`$this['message']->getError()` returns `sfValidatorError` object -
maybe something changed in symfony 1.4 and it isn't iterable
anymore...
At first I thought that all magic in that example happened because of
object being placed in `$error` by iteration implements __toString()
but it seems no iterations happens at all...
