integer field

[Michael Wang <mi...@s1.com>]

Does anyone know how to get rid of default value of 0 from integer input
field?
I would like to see empty field instead of 0 inside.

Any help will be appreciated
.
Thanks

The simplest way is to have this field as a String, and making a
conversion to String / Integer at ActionForm class.

There isn't any way to this because the int will
always have some display value.  You would need to
have the field setup as a String and then convert it
to an integer later.  Also, you will probably want to
perform validation on the field to make sure it is an
integer.

The best way to do this is to use a String property in your ActionForm
bean, rather than an int property.  That way, you can initialize the
visual appearance however you like (a null string will be displayed as an
empty field), and the error-redisplay logic will work correctly.

In your validate() method, one of the things you will want to check is
whether the conversion from String to integer was OK or not.
