Hi Dave,

haven't gotten around to looking at your block, but I presume it uses message passing to emit PMTs, is that right?

In that case, the "message debug" block has a "store" input.

Best regards,

Anyone able to help out?  Hoping it's just something dumb that I didn't set properly.

I am attempting to test a block that takes in complex samples and outputs PMT objects.  In order to properly test it, I need to run a vector through it and verify that the correct number of PMT objects were created.  Thus far I have not run across any blocks that act like a vector sink for PMT objects.  So, I created my own in Python.  When I run with the custom PMT sink the graph never stops.  If I create the same PMT sink in C++ then everything works as expected.  Attached is some example code.  If you build gr-poopie with `cmake .. && make && sudo make install && sudo ldconfig` you can then run the `test.py` script in the base directory.  It should work for the first three tests and then hang on the last one.
