Setting a form field value as an empty string?
(Using Cocoon 2.1.8)
I'd like to be able to set the initial, default value of a form to be an empty string;
at the moment, if the user does not fill in a value, then it gets treated as a NULL
value when passed to the database.
I have tried:
<fd:initial-value></fd:initial-value>
and
<fd:initial-value> </fd:initial-value>
but am still getting a NULL result.
Any help is appreciated.
Thanks
Derek

No, I mean that when it comes back from the form it is NULL.

You mean it's correct in the form, you don't see null on the screen, but in the
database it is NULL? Then I guess you have to fix your binding.

Does this mean that the patch is available in the version 2.1.10?
I have also come to the conclusion that this still does not help me.
What I need is some way to tell Cocoon to pass an empty string
(not "whitespace" per se) and not a NULL from an empty field:
that might require another patch e.g.
<fd:initial-value null="true"/> - default (current) behaviour
<fd:initial-value null="false"/> - overrides a null value from an
empty field with an empty string instead when processing values
returned from the form.
This option will (obviously) only be applicable to string-type fields.
