Re: Pool Module Question

For the time being, I'll try to stick with mod_python and upgrade to 2.x  I may have to revisit the proxy server option if this doesn't work.

I've upgraded to 2.0.3 and it worked until something was saved in the pool.  Now, anytime I use the [[.import names="pool"]] directive, I get the following error:

-- BEGIN PASTE --
Unexpected exception: (please report!)
Traceback (most recent call last):
  File "/usr/share/spyce/spyce.py", line 288, in commonHandler
    thespyce.spyceInit(request, response)
  File "/usr/share/spyce/spyce.py", line 588, in spyceInit
    self._startModule(modname, modfrom, modas, 1)
  File "/usr/share/spyce/spyce.py", line 573, in _startModule
    mod.start()
  File "/usr/share/spyce/modules/pool.py", line 44, in start
    self._pool = pickle.load(f)
ImportError: No module named detectives
-- END PASTE --

Notes:
1) The missing "detectives" module refers to the class of the object saved in the pool.
2) This is happening immediately on the import directive, I do not have to try to access the pool value to get the error.

This looks more like a configuration error to me, rather than a backwards compatability issue, however I get a similar error wether using mod_python or fcgi.

Thanks again.
