Re: [Wicket-user] Conditionally updating model

[Andrew Berman]

Whoops, my method should be getInput not getValue....Sorry.

Should be:

public String getInput() {
     String val = super.getInput();
     if (val != null && val.trim().equals(""))
           return null;

     return val;
}

There are a bunch of ways to do it, but I think the easiest way is to override getInput() and return null if you do not want the model updated with this component's value.

For example,

public String getValue() {
     String val = super.getValue();
     if (val != null && val.trim().equals(""))
           return null;

     return val;
}

Hi,

I have an "edit user" page that allows the admin to update various
details for a user, like email address, name, etc.  The admin can also
change the password for a user, but I want to make that optional, like
the password is only updated if the admin actually types a new
password, otherwise the User object backing the Form isn't updated
with a blank password.

Is there a suggested way to go about this? Do I end up overriding
getModelValue() or setModelValue()?

Thanks for your time.
