 I think the default property expects one item of your list, so either 1, 2, 
 3, 
 5 or 7, not all of them.

No it doesn't. default=1 generates this error:

 ConfigurationError: ('Invalid value for', 'mynumbers', (1, type 'list'))

 If you want to define the set of selectable values you maybe rather want to 
 use a Choice field and specify the values property. Or set a Choice field as 
 value for value_type.

I don't really need Int as list items but some more complex objects.
This works quite well - except of the missing default.

Frank

FWIW, I just think it's a bug that this doesn't work.  Have you put  
it in the collector?

 myline=TextLine(
title=_(A line of text),
required=True,
default=u'default test'
 )

 I'm using an 'addform' to add self made objects to my site but
 unfortunately the list mynumbers is not initialized with those 5 default
 numbers. The default value of myline is displayed correctly on the add
 form.

 Does anyone know, how this can be fixed?
