$RCSfile: CreationDialog.py,v $
Implements the GUI mini-workflow invoked from the Zope Management
Interface to create an instance of ExternalFile. This source code has
been factored out of ExternalFile into this separate module for the
reasons listed below:
1. This code is not strictly necessary to use ExternalFile, and in
certain cases (for example, when creating instances programmatically)
one prefers to bypass this code altogether and call the ExternalFile
constructor directly.
2. There are a great many possible error conditions or alternative
scenarios that may occur when creating an instance of ExternalFile TTW
(through the web), resulting in many lines of code. This code was
threatening to obscure the actual implementation code when it was all
contained in the same module.
3. Zope3 introduces an architecture where GUI handling code and Zope
object implementation code are kept separate and knit together
declaratively through the use of a deployment descriptor. This allows
alternative GUIs to be plugged in and makes the code much more
general. For example, it could be used in non-Zope environments.
Creating a separate module for GUI stuff moves us in that direction.

Workhorse method called from create.pt form. Actually does the
work of confirming the user's intended (possibly destructive)
actions, creating the target file if necessary, and calling
create_object to actually create the object. This method may be
called from create callbacks of derived classes to do the heavy
lifting.

overwrite the contents of the server file with the uploaded file

Factory method to create an instance of ExternalFile, called
from a GUI in the Zope Management Interface. It calls
addExternalFile to actually do the work.
