Hi,

I'm trying do modify the template for a page so that the admin can select where a certain element on the page redirects. I'm trying to use something like the following:

static $has_one= array(
        "InternalLink" => "SiteTree"
);

The field shows up in the CMS and I can edit the link. But when I save it it doesn't seem to be persisted into the database, and the link when viewing the page just points to $siteroot//

I've built the site and a field called examplenameID does show up in the database. But it never changes from 0.

What am I doing wrong?

Kind regards

Are you using a TreeDropdown field for selecting the site tree or a dropdown field?.

With these you will need to make sure that the field name includes the id - RelationshipNameID rather then just RelationshipName

new TreeDropdownField('InternalLinkID', 'Link'...

That was the key, I changed the parameter and everything started working.

Thanks!
