The skin setup looks good.

Also good.

I am pretty sure that you need the FormLayoutSupport *before* the EditForm and 
DisplayForm in your inheritance order. The super-classes are read from right 
to left, and the layout support in FormLayoutSupport overrides attributes in 
DiaplayForm and EditForm.

Since you have issues with security, make the permission zope.Public for now.

Looks all good.

I guess Hermann solved this problem already, suggestinbg that you need the 
++skin++ declaration.
