dtml-in will accept four differen formats: a list of objects with
attributes, a list of values, a list of dicts, or a list of pairs.
A list of objects is the most common case, and you get access to the
attributes by name inside the loop. A list of values can only
be accessed using <dtml-var sequence-item>, which gives you access
to each item in the list in turn. For a list of dicts you want
to specify the 'mapping' keyword on dtml-in, in which case the
keys of each dict can be used in dtml-var statements. I'm not
100% sure what the list of pairs does, but I think one of the
two items in the pair goes into sequence-key and the other into

If you make the right security declarations you can probably access
a class variable from dtml. What might be easier, though, is to
use the binding feature of DTMLFile to make the list available
when the method is called, via pre-declaration in your Product:
[code that defines your class, including the class variable listOfMethods]
yourAddMethod = DTMLFile('dtml/addForm',globals(),
listOfMethod = yourclass.listOfMethods)
I'm not 100% sure this is going to solve your problem, but I've some
some stuff along these lines successfully, so it might.
