Re: [Zope-dev] Decimal validation error.
Thanks Hermann, This still does not work for me. The pattern = '#,##0.' seems to have no effect on the converter. Perhaps I'm doing something wrong, I'm posting my setup below. This most certainly have to be a bug in the system if you can't put 1.2345 into a decimal field, no? If so is there a bug tracker for z3c.form where I can post this and get it fixed? #interfaces.py class IFixedDecimal(IDecimal): """Fixed decimal field.""" class FixedDecimal(schema.Decimal): interface.implements( IFixedDecimal) class ITaxLot(interface.Interface): """A tax lot""" quantity = FixedDecimal( title = u'Quantity', required = True) #holding.py class MyDecimalDataConverter(DecimalDataConverter): """Adapt decimal data converter""" adapts(IFixedDecimal, IWidget) # The amount of '#' after the '.' outlines the no. of decimal places pattern = '#,##0.' #configure.zcml #overrides.zcml On Thu, Feb 11, 2010 at 3:21 AM, Hermann Himmelbauer wrote: > Am Mittwoch 10 Februar 2010 17:27:09 schrieb Mats Nordgren: > > I have an interface with a decimal field.

Re: [Zope-dev] Decimal validation error.
Seems a plain vanilla install of bluebream validates decimals fine with zope.app.form. Does z3c.form validate decimal fields or is that delegated to zope.schema?

[Zope-dev] Decimal validation error.
I have an interface with a decimal field. It validates fine for 1,2 and 3 fractions but if I enter a decimal with 4 fractions I get validation error "The entered value is not a valid decimal literal." I'm using the pypi release of bluebream and z3c.form 2.3.2.
