When I tried to make a small example of the problem, it just works.

Introduction to Flask can be found here:
http://flask.pocoo.org/

A simple example:

hello.py
"""
from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"
"""

$ pip install Flask
$ FLASK_APP=hello.py flask run
 * Running on http://localhost:5000/

But for debugging I got a hint from
https://wingware.com/doc/howtos/flask

and the script is changed to:

hello.py
"""
from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    retstr = "Hello World!"
    return retstr


if __name__ == "__main__":
    # Preferably check if Eric debugger is active before switching off
Flasks internal debugger
    app.debug = False # Switch off Flask internal debugger.
    app.run()
"""

This works fine in the Eric debugger


But for some reason this doesn't work in the program I want to debug.
It doesn't stop at my
breakpoints. But when I moved the debug to a parameter in the run
command it works.

if __name__ == "__main__":
    #app.debug = False
    app.run(debug=False)

Now it works perfectly :)
