Loading validation rules for pages rather than webforms

It is possible to add webform components to pages and that in itself works fine. It is then possible to also add validation rules, which also work fine. However, existing rules are not listed even though they continue to be processed.

The issue is at line 23 of webform_validation.admin.inc

function webform_validation_get_webform_rules($node) {
if ($node->type == "webform") {
$webform_nid = $node->nid;
$rules = webform_validation_get_node_rules($node->nid);
}
return $rules;
}

I changed this to:

if ($node->type == "webform" || $node->type == "page") {

and that works fine.
