Thanks for that code.  I implemented the widget as a
product (had to do some imports) and the product
loads successfully.

However, when I make use of the widget

        <widget
            field="all_subscribers"
            class="Products.TupleTextWidget.TupleTextAreaWidget"
        />

the following message appears on the edit page

Error Type

    TypeError
Error Value
    __init__() takes exactly 3 arguments (4 given)


with the following traceback:

[...]

    * Module zope.app.form.utility, line 224, in setUpEditWidgets
    * Module zope.app.form.utility, line 101, in setUpWidget
    * Module zope.app.form, line 120, in __call__
    * Module zope.app.form, line 102, in _create

Do you know what needs to be changed here for this to work?

Thanks,

Morten
