Hello all, Once again I find myself stuck, hoping someone might help me out: I have created a ZClass and added a propertysheet. However, I am experiencing some problems when defining the separate properties: - When I define a property to be of type 'date' I cannot leave the "value" empty. Is this a bug or is there a specific reason for this? - When I want to add a selection, I added another property of type "lines" to hold the different selection items. However, I do not want this extra property with the lines to show up on my edit screen when I manage my objects. Is this possible? - When I have created a property I cannot seem to change its name. I have tried to find the answers in the available documentation but didn't find it. Can someone please help me out here or point me to some rtelevant information I might have missed? Thanks in advance, Arjan Huijzer __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable. Sign up now. http://mailplus.yahoo.com
