[Zope] Migrating the OpenFlow project from Zope 2.7.x to 2.9.x (and 2.10.x)

[Marco Bizzarri]

Hi all.

I'm in the business of migrating OpenFlow from Zope 2.7.x (where it
lived peacefully) to Zope 2.9 and 2.10 (i.e. I'm in the process of
2.9, and then I will move to 2.10).

As a first step, I've run the unit tests for the project, and just one
is failing, the following one:

<code>
    def afterSetUp(self):
        self.zope = self.app
        # create an openflow
        self.zope.manage_addProduct['OpenFlow'].manage_addOpenflow(id='OF')
        self.of = getattr(self.zope, 'OF')
        # Create a Process Definition with two activities (Begin, End)...
        self.of.addProcess(id='begin_end', BeginEnd=1)
        self.pd = getattr(self.of, 'begin_end')
        # ...and one transition linking them
        self.pd.addTransition(id='begin_end', From='Begin', To='End')
        loginUnrestricted()

    def testCopyOpenflow(self):
        cataloged_items = len(self.of.Catalog())
        cb = self.zope.manage_copyObjects([self.of.id])
        try:
            for i in [self.of, self.pd] + self.pd.objectValues():
                assert hasattr(i.aq_base, 'getId'), "missing %s" % i.id
                assert i._getCopy(self.zope) is not None, "getcopy not
in %s" % i.id
        except AssertionError:
            # this test is tough to make! how to do this?
            return
        self.zope.manage_pasteObjects(cb)
        new_of = getattr(self.zope, 'copy_of_'+self.of.id)
        self.assertEquals(len(new_of.Catalog()),cataloged_items)
</code>

Just for a little of further knowledge: OpenFlow creates a Catalog,
which is used to access all the data of the Workflow (processes,
instancess, workitems, etc.)

The assertion failing is the last one, because I get a length of 0 as
a result of the query of the catalog.

Can someone point me to differences between 2.7 and 2.9 in the
handling of the paste action?

Regards
Marco
