I remember that one - quite cumbersome. Try something like this:
# You should use the following interface for your forms:
class IMyDecimal(IDecimal):
"""Specify custom decimal interface"""
# Now create a custom data converter
class MyDecimalDataConverter(BaseDecimalDataConverter):
"""Adapt decimal data converter"""
adapts(IMyDecimal, IWidget)
# The amount of '#' after the '.' outlines the no. of decimal places
pattern = '#,##0.####'
# And specify in overrides.zcml
<adapter factory="mymodule.MyDecimalDataConverter" />
This works for me.
Best Regards,
Hermann
