I've run across something similar in my coding. It turns out that the order
of imports is important (at least it was). I discovered this months ago and I
believe I reported it to the list.
I import the python stuff I need.
import sys
import re
import math
import decimal
import datetime
import time
Then I import the Dabo stuff.
import dabo
dabo.settings.dateFormat ="%m/%d/%Y"
import dabo.dEvents as dEvents
import dabo.dException as dException
import dabo.ui
then
dabo.ui.loadUI('wx')
and after the above I can import most anything I've created
from RAClasses import SchGridBizobj, HeaderToolBar, AppMenu, PesAbout,
Getlatitudelongitude
It works for me.
