I am folllowing a walk through on using the data object manager in siteconfig (http://archive.ssbits.com/2-4-working-with-siteconfig/). I have managed to get it working to the point where I can add objects to the backend but I can't seem to get them to display on the template.

I am trying to loop through all items inside the object using a control loop but i don't seem to be having any joy... I get an error message [Notice] Undefined index:

Template

<% control SiteConfig.NemoMembers %>
    <p>$Name</p>
<% end_control %>

Please help, I have looked through other forum posts and haven't managed to get it to work. Please tell me it's something stupid that I have missed. It is driving me mad not being able to get it to work!

Many thanks,
Alex

I just bumped on the same problem.. So subscribing on this thread
Any help would be awesome!

You can create functions inside the SiteConfigExtra class that return dataobjects:

function NemoMembers() {
    return DataObject::get('NemoMember');
}

Then you can output them in any template file like this:

<% control SiteConfig %>
    <% control NemoMembers %>
        <p>$Name</p> 
    <% end_control %>
<% end_control %>
