[Zope] Get the text, not the result, from external_validator field

[Ralph vd Houdt]

Hi All,

For development purposes I am writing myself an overview of all my Fomulator
Forms. In this overview I'm trying to print the text, not the result, of the
external_validator field of a specific fomulator field.

Does anyone know how to get the text of that field? I started like this and
tried everything:

"container['the_form'].get_field('the_field') --- how to get the external
validator text ---"

Greetings Ralph vd Houdt
