[Zope-Coders] Re: Catalog.py

[Andreas Jung]

This is fixed by the following:

# Collector #771: provide a safe_callable() method with a
# fallback (when ZCatalog might be used outside Zope)

try:
    from DocumentTemplate.cDocumentTemplate import safe_callable
except:

    def safe_callable(ob):
        # Works with ExtensionClasses and Acquisition.
        if hasattr(ob, '__class__'):
            if hasattr(ob, '__call__'):
                return 1
            else:
                return type(ob) in ClassTypes
        else:
            return callable(ob)

I can not see anything wrong with this code?
