Agreed, we can't use different names and ids!
We can use camel bucket names instead of dots. This
means we can convert each first letter of a prefix to a
uper case letter. But the first letter should be lower case.
This wil give us names and ids like:
This should also work if somebody uses already a camel
bucket name for lastName e.g.
because we do not need to resolve/split the prefix based on
the formWidgetsLastName string base. We do only split such prefixed
strings based on the prefix parts itself.
But another question is, why do we use additional dots or
someting else between prefixes? I guess we should skip it and
just append each prefix. This alloes us to use the pattern above
as well by choosing our own camel bucket names if needed.
Any reason for using dot prefix for our prefixes? If not
I propose to skip the additional dots which are only beautifiers.
What do you think?
