Updated as follows, based on Diez's instructions.

Quote: Diez
"the problem is your usage of enumerate as option-list constructor.
This is a *generator* object. Thus after the initial display of the
form, it's exhausted.
I didn't notice that before, even though your shown code-samples in
the ML had that error. I guess that's because your code is pretty
convoluted - mixing form-declaration & creation of these lists into
the class-scope is a bit on the wierd side IMHO.
All you need to do is to wrap the generator into a list:"
===============
class applicationControlForm(TableForm):
class fields(WidgetsList):
installDict = getExecutables()
applicationList = []
hover_help = True
for each in installDict:
if each == "DMT" :
pass
else :
applicationList.append(each)
controlApplicationOptions = list(enumerate((applicationList)))
controlApplication = SingleSelectField('Application',
options=controlApplicationOptions, \
help_text = 'Please
select the Application to control.')
controlActionOptions = list(enumerate(('start', 'stop')))
controlAction = SingleSelectField
(options=controlActionOptions)
submit_text = 'Save Movie'
create_applicationControlForm = applicationControlForm
("create_applicationControlForm", action='executeForm')

Thank you so much, I really appreciate the help.
