Hi, I used http://www.zope.org/Members/beno/HowTo/HowTo/Formulator_With_ZPT as an example how to use Formulator with ZPT. Unfortunately it seems not possible to use ZPT exclusively because a Python Script is necessary to evaluate the input. This is no problem in prinziple but this script does something ugly in case that some input is erroneous: "Use the back button of your browser ..." Well, this is something which conflicts with guidelines of good web design and thus I tried to work around this but failed. I even failed in accessing the input values of the form. My main problem was that I did not found a description of the keys which can be used in the field.get_value() dictionary. The ideal solution would be to get those previousely filled values into the original page template and mark the erronous input in any common way. Any hints how to accomplish this? Kind regards Andreas.
