python function returns immediately after any clips command

[srajan3012]

;;--- KB.clp---;;
deftemplate fact_template(
   (slot slot_1 (type SYMBOL))
)

(assert (fact 1))

(defrule rule1
  (fact 1)
  =>
  ?p <- (assert (fact_template (slot_1 v_1)))
  (py_foo ?p ))

# run.py
import clips
clips_env = clips.Environment()
clips_env.load("KB.clp")

def py_foo(p):
   p['slot_1'] = 'slot_value'
   p.assertit()
   print "Done"

clips_env.define_function(py_foo)
clips_env.run()

anything after assertit() is not executed.

Please provide a MWE which reproduces your issue. With the provided example I can't say much. What are the symbols fact_template and python_func?

updated example.

Closing this as invalid, please check issue #13 for explanation.

More precisely: you cannot change or re-assert an already asserted fact.
