Hier_blocks2 error

GNU Radio
1

I am using gnruadio 3.7.8. I have a module (python) which is working
well
for version 3.6.3. In made necessary changes so that it can work with
gnuradio 3.7.8. However I am getting following error

File
“/usr/local/lib/python2.7/dist-packages/gnuradio/gr/hier_block2.py”,
line 92, in getattr
return getattr(self._impl, name)
AttributeError: ‘hier_block2_sptr’ object has no attribute ‘_hb’

I spent a lot of time to figure out this but could not resolve it, so I
thought to get help from mailing list.

Is this a bug or I am doing something wrong?

What your seeing is the interface wrapper looking for an attribute in
the wrapped instance ‘self._impl’ which used to be called ‘self._hb’. So
it tries to lookup that first - and fails. Since both _impl and _hb are
marked protected they should not be accessed from outside the wrapper
directly (I remember some WXGUI code did that, but that has been fixed).
In the gnuradio tree I can’t seem to find anything like this.

Can you check and see from where this Exception is raised from?
