Validation highlighting not working

Hello,

I’ve noticed that, on validation failure, the red background shows only for a one-line text input box. It does not work when rows are specified for text input controls, nor for selection drop-downs.

For example, this code shows a red background when failing the edit:

        [code]{
	type: "input",
	name: "Title",
	label: "Title<span class='required_marker'>*</span>",
	value: "",
	width: "750",
	validate: "custom_title"
    }


function custom_title(value) {
if (!dhtmlxValidation.isNotEmpty(value))
return “Input must not be empty”;
return true;
}[/code]

Whereas no background shows when this validation edit fails:
{ type: "input", name: "Justification", label: "Justification<span class='required_marker'>*</span>", value: "", width: "750", rows: "3", validate: "custom_justification" } ... function custom_justification(value) { if (!dhtmlxValidation.isNotEmpty(value)) return "Input must not be empty"; return true; }

Any help would be greatly appreciated. Thank you.
