Don't know if this is the right forum for this but... yeah... anyway...

For various reasons I have to do a custom made user system kind-of -thing. I have a dataobject which represent the member that looks like this:

<?php
class Medlem extends DataObject {	
	static $db = array(
		'Fornamn' => 'Varchar',
		'Efternamn' => 'Varchar',
               ...
         	'Losenord' => 'Varchar(64)'
	);
	static $has_one = array(
		//'Avatar' => 'Image'
		'MinOrganisation' => 'Organisation'
	);

	function getCMSFields_forPopup() {
	
		$fields = new FieldSet(
			new TabSet("Root",
				new Tab(
				$title = 'Main',
					new TextField("Fornamn", "Förnamn"),
					...
					new CalendarDateField("Medlemsdatum", "Datum för medlemskap")
				),
				new Tab('Medlemsuppgifter',
					new HeaderField("Medlemsuppgifter"),
					...
					new ConfirmedPasswordField('Losenord','Lösenord',null,null,false,'Bekräfta lösenordet')
				)
			)

		);
	        return $fields;
	}
}
?>

The problem is that the ConfirmedPasswordField doesn't validate. Seems like there is some javascript missing but I can't figure out how to get it there. Anyone who knows?

Anyone?

I'd say have a look at the popup that occurs with MemberTableField. Afaicr there's a confirmedpasswordfield as well, see how that works.

In most cases, js-validation of formfields did not work in the CMS (2.3 will be different I think), only on frontend. Not sure how it's with the passwordfield though - but I do know the popup of membertablefield has it - so I figure your solution must be there.
