[Zope] Using a multiple_selection property in a product

2001-01-03 Thread Ronald L. Roeber 

I am attempting to build a product that will contain some unique
information and access control for services in  support of college
classes. Many, many things are going well...better than expected.
However I am having problems getting the product to correctly recognize
a multiple selection property. The property is the days of the week that
the course is offered. ( Monday-Wednesday-Friday or Tuesday-Thursday, or
any combination thereof)

The DTML for the product creation form contains the following:
---
   th align="LEFT" valign="TOP"emDays Course Offered/em/th
   td align="LEFT" valign="TOP"
   select name="classdays:multiple_selection" size=5 multiple
option value="Monday"Monday/option
option value="Tuesday"Tuesday/option
option value="Wednesday"Wednesday/option
option value="Thursday"Thursday/option
option value="Friday"Friday/option
   /select


in the product class I have tried two tactics (actually more but I'll
confess to only these two)

_properties(
{'id':'classdays',
'type':'multiple_selection','mode':'w'}, ...

RESULT: product installs, but classdays in an "unknown property type"

so I try this:

_properties(
{'id':'classdays', 'type':'multiple
selection','mode':'w'}, ...

RESULT: product installs, however the Properties are unavailable,
furthermore trying to view the properties by clicking on the Properties
tab generates the following Zope error:

Error Type: NameError
Error Value: select_variable

[somewhat helpful troubleshooting suggestions]
