Incompatibility with OpenMDAO 3.2+

[christophe-david]

It looks like the new auto-ivc feature of OpenMDAO 3.2 breaks things in wop.

Provided you have already connected once to WhatsOpt server, the following snippet should work with OpenMDAO 3.1 but should break with OpenMDAO 3.2 or 3.3.
Uncommenting the line that adds the IVC to the group makes the script work again.
Also, the code works in all case if components are added directly in problem.model with no additional group added.

import openmdao.api as om
from whatsopt.show_utils import generate_xdsm_html
from whatsopt.whatsopt_client import WhatsOpt


class SomeComponent(om.ExplicitComponent):
    def setup(self):
        self.add_input("foo")
        self.add_output("bar")

    def compute(self, inputs, outputs, discrete_inputs=None, discrete_outputs=None):
        outputs["bar"] = inputs["foo"]


problem = om.Problem()

ivc = om.IndepVarComp()
ivc.add_output("foo", 10.0)

group = om.Group()
# group.add_subsystem("ivc", ivc, promotes=["*"])
group.add_subsystem("comp", SomeComponent(), promotes=["*"])
problem.model.add_subsystem("group", group, promotes=["*"])

problem.setup()
problem.final_setup()

wop = WhatsOpt(login=False)
ok = wop.login(echo=False)
if ok:
    xdsm = wop.push_mda(
        problem, {"--xdsm": True, "--name": "dummy_test", "--dry-run": False, "--depth": 1}
    )
    generate_xdsm_html(xdsm, "xdsm.html")
