Can you post the traceback? There should be an attribute named
'_cachedForm' that is common to all UI objects.

Again, the traceback is essential to find out what isn't working.

OK, here's a quick explanation:
class dPanel(_PanelMixin, wx.Panel):
def __init__(self, parent, properties=None, attProperties=None,
*args, **kwargs):
self -> automatically sent by Python to all instances. You never
send it yourself.
parent -> Required. Only forms and dialogs can exist without being
'contained' by another control. The parent parameter is a reference
to the object that will contain the panel you are creating.
properties=None -> You can pass properties as a dictionary, with the
prop name as the key, and the initial value as the value. Defaults to
None; you can therefore safely ignore it if you don't need it.
attProperties=None -> Just like the properties parameter, except
that the values are all strings. This is used when retrieving
properties and their values from an XML file, such as a .cdxml class
definition. Unless you're writing something that directly interprets
such files, you can ignore this.
*args, **kwargs -> Catch-all for any additional arguments and
keyword arguments, respectively. I don't want to go into a whole
explanation, as there are many available on the web (try: http://
www.network-theory.co.uk/docs/pytut/KeywordArguments.html, or http://
tinyurl.com/yprwyu), but this is the magic that allows for the sort
of flexibility Paul built into Dabo to pass arbitrary properties to
objects when they are being created.
