...

I've a class with a property myparent This property needs to be set after a new instance is added or when the instance is moved.

Thanks to people from the list, I know I've to make an external method and add the external method manage_afterAdd to the methods of the class.

This is how the method looks:

def manage_afterAdd(self,item,container): item.myparent=container.id return

This is a ZClass, right?

It should be:

item.propertysheets.YourPropsheet.manage_changeProperties({'myparent' : container.id})

Kevin

Yes, it's a ZClass with in it's method's tab an external method called : 'manage_afterAdd' The external method itself is python code (see source above) The intention of this method is that it sets the 'myparent' property to a value (dependend on its parent) when an instance of the ZClass is created or when the instance is moved. The problem is that nothing happens! 'myparent' property keeps empty. I also don't get an error value... What do you mean by keeps empty. Is that in the sense of: <dtml-var myparent> does not yield a (the right) value? or in the sense of: I can't see the value of the property in the property screen of the instance. That last thing may happen, and still the property may be set. Try using the dtml-var in the view method of you ZClass. If you want the property to show if you consult the property tab, you may have to remap the manage_Properties (or whatever it's) called view in the ZClass definition. Rik
