Hi, I setup a Specialist with a ZCLass "AZ" for persistent storage. In AZ I setup a Dataskin propertysheet "Basic" with properties Name, Street etc. Now I made dtml-method form which iterates with: <dtml-call "REQUEST.set('ni',getItem(sid+id))"> <dtml-in "ni.propertysheets.Basic.propertyMap()"> over the Basic propertysheet,builds the form, and stores the values within another dtml-method edit with: <dtml-call "ni.propertysheets.Basic.manage_changeProperties(REQUEST)"> this works fine. Now I wanted to have attributes which I don't want to display in the form, for example complete attribute. I therefore created another dataskin propersheet Internal in AZ with a property complete and tried to set it with: <dtml-call "ni.propertysheets.Internal.manage_changeProperties(REQUEST,complete='1')"> But I don't manage to store retrieve this attribute. All attributes in the Basic propertysheet I can store and retrieve. what is the magic behind this ? Mit freundlichen Grüßen Joachim Schmitz AixtraWare, Ing.
