Of course. Call it a momentarily lapse of reason -- I wasn't thinking clearly. Honestly! :-) I remember being somewhat annoyed by this at one point as I could not find a way to cleanly handle class construction -- I ended up putting a check in the class' index_html and creating my instances there, which is an ugly but functional hack. I still think ZClasses should be permitted to expose constructor-like methods. The form-handling code you described works but is hardly a "neat" solution. -- Alexander Staubo http://www.mop.no/~alex/ "He could open a tin of sardines with his teeth, strike a Swan Vestas on his chin, rope steers, drive a steam locomotive and hum all the works of Gilbert and Sullivan without becoming confused or breaking down in tears." --Robert Rankin, _The Book of Ultimate Truths_

...

Speaking of which, has anybody tried using Confera from within a ZClass? It would be much more elegant that was Cees describes. Question being: Would Confera store its messages in the instance, or in the class?

-- Alexander Staubo

You would need to arrange for your ZClass to create a new Confera _instance_ in your new object instance at construction time. If you plopped a Confera instance into the actual ZClass, that Confera instance would be shared by all instances of that ZClass - this would be the case for _all_ mutable objects, exactly like in python.

For example, to create an object where each instance has its own list attribute (mutable object) in Python, you would do:

class foo: def __init__(self): self.data=[]

You would _not_ do:

class foo: data=[]

...because all foo instances would share the same data list.

Hope this helps!
