Suppose you have a form with two fields defined on it. The value of
those two fields comes from the value of an intake field. The data in
the intake field came from the attributes of a mapped object (let's call
it person).
Here are the relevant field names and values on the HTML form:
FirstName=John
LastName=
Let's now say that you change the value of the LastName field to "Smith"
and you clear the contents of the FirstName field. You now sumbit the
form to an action. The action gets the intake group and sets the value
of your object with the values from the html form. You would think that
the result of person.getFirstName() would be null or an empty string and
that person.getLastName() would be "Smith". You are wrong.
What really happens is person.getLastName() returns "Smith" and
person.getFirstName() returns "John".
I am hoping that there is a work around to this issue. I would be
shocked if no one out there using turbine with intake has not run into
this issue. The way it appears to me, I simply can not use an html form
to edit data from a persistent object and save it back to the database
if that change is to remove the value from a field.
This issue exists with T2.1 and T2.2.
