Make sure you use the correct parameter for the editPage() call (in my 
previous message I left them all out).

I had some more thoughts about what you're trying to realize, and what 
this actually is is 'record polymorphism'.

What would really be nice to have is a generic way of doing a thing like 
this.

Suppose in the future you could do this:

class contract extends atkNode
{
  function contract()
  {
     .....
     $this->setDiscriminator("type",
            array("hosting"=>"hosting_contract",
                  "support"=>"support_contract"));

  }
}

class hosting_contract extends contract
{
  function hosting_contract()
  {
     ...
     // all specific hosting contract stuff.
  }
}

etc...

So by defining which field is the discriminator, and by mapping 
discriminator values to nodes, the system would then be able to 
instantiate the correct subnode.

I've toyed around with a similar feature a while ago, but abandoned it 
because it would take too much time for what I needed it for at that time.

Greetings,
Ivo
