Conditionally views and wizard.steps.current maximum recursion depth exceeded

[edgaru]

When I use wizard.steps.current into a conditionally function I get maximum recursion depth exceeded.

Code Example:

def conditionally_view(wizard):
     if (wizard.steps.current == 'insurance_coverage') and ('emision_retries' in wizard.request.session) and \
            ('emision_has_error' in wizard.request.session):
          ....

Traceback:

RecursionError: maximum recursion depth exceeded

I solved it using wizard.storage.current_step instead wizard.steps.current.

This problem was reintroduced for me in 2.4 and using wizard.storage.current_step does not fix it.

The example at https://django-formtools.readthedocs.io/en/latest/wizard.html#conditionally-view-skip-specific-steps

does not work with version 2.4 due to this

Is there a version where this is not an issue?

Is there a version where this is not an issue?

Version 2.3 does not seem to be affected; instead, I confirm that updating to 2.4 breaks the example.
