[Zope] finding the type of an object

[Marcus Collins]

Hi,

Rather than trying to determine the type afterwards, you can actually
specify in your form tag that name is to be treated as a list.

Use:

  <select name="name:list" multiple>

and Zope will coerce the input into a list.

See the excellent How-To on form variable types:

hth,
