Try this: _properties = (.... {'id':'classdays', 'type':'multiple selection','mode':'w', 'select_variable': 'days'}, ...) days = ( 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday' ) -Randy -----Original Message----- From: Ronald L. Roeber [mailto:rroeber1@unl.edu] Sent: Wednesday, January 03, 2001 2:48 PM To: zope@zope.org Subject: [Zope] Using a multiple_selection property in a product 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"><em>Days 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] Traceback (innermost last): File /home/Zope-2.3.0a1-src/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /home/Zope-2.3.0a1-src/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/Zope-2.3.0a1-src/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /home/Zope-2.3.0a1-src/lib/python/ZPublisher/Publish.py, line 171, in publish File /home/Zope-2.3.0a1-src/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_propertiesForm) File /home/Zope-2.3.0a1-src/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_propertiesForm) File /home/Zope-2.3.0a1-src/lib/python/App/special_dtml.py, line 120, in __call__ (Object: manage_propertiesForm) (Info: /home/Zope-2.3.0a1-src/lib/python/OFS/properties.dtml) File /home/Zope-2.3.0a1-src/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: manage_propertiesForm) File /home/Zope-2.3.0a1-src/lib/python/DocumentTemplate/DT_In.py, line 691, in renderwob (Object: propertyMap) File /home/Zope-2.3.0a1-src/lib/python/DocumentTemplate/DT_Util.py, line 337, in eval (Object: hasProperty(select_variable)) (Info: hasProperty) File <string>, line 0, in ?
