With the upcoming release where a Python IDE will be integrated with FME, the next, and most important logical steps is to pass cached data into the IDE for the purposes of debugging calculations and logic flow. 

I do not know how the integration with the Python IDE will be released but being able, at design time, to open the IDEA in debug mode is a powerful way of seeing how cached data flows into the PythonCaller, through the python logic, and then back out again.

Hi ​@pcgveenstra, thank you for raising this IDEA. 

For full transparency, we initially scoped out the ability to debug with caches when implementing the external IDE.

Initially the only way you will be able to debug is by closing the PythonCaller/Creator and running the Workspace to inspect your output. 

I agree that adding debugging using caches is the logical next step. I would be interested to see how much interest we can gather from the community. Moved this to Gathering Interest :)
