[Zope3-Users] how to use invariant/validator? (z3c.form=1.6 and z3c.formui=1.3)

[Mail_fuer_Kai at gmx.de]

Hi,

I want to use an invariant-check in an analogous manner like it is described at the end of the message.
There is answered that the bug is fixed, but the same causes are still active.
I'm using z3c.form=1.6 and z3c.formui=1.3
What seems to be the trouble now?

my code:
class IAddressSearch(zope.interface.Interface):
    ...
    @zope.interface.invariant
    def firstnameOrSurname( search ):
        #import pdb; pdb.set_trace()
        if search.firstname == None:
            search.firstname = u''
        if search.surname == None:
            search.surname = u''
        if len(search.firstname) == 0 and len(search.surname) == 0:
            raise zope.interface.Invalid( u"""Enter firstname and/or surname.""")


result of my Code:
TypeError: tuple indices must be integers

Hi Peter,

I just checked in a fix for this problem into z3c.form and z3c.formui. It 
actually turned out that I had to fix2 bugs and add a feature to solve the 
problem. But it should be working now.

I did not make a new release yet, but will do that soon too.

Please let me know, if it is still not working!

Regards,
Stephan



Many thanks!
