I've had the same problem before. You're probably setting the options list
in your form before hand like so:
form.setListOptions(someList);
But on the next request your form is recreated and you're not repopulating
the value.
What you should be doing is in the getListOptions method of the form,
instead of returning a local list variable, you should be retreiving the
list from elsewhere every time.
ie
getListOptions()
{
return SomeOtherClass.getList();
}
Either that or put your form in the session scope, instead of the request
scope.

Subject: re-populating dropdown boxes
I've just started a project on struts and i'm facing a problem while doing
validations in ActionForm. Say if i have a textbox and a dynamically
generated dropdown box in my page and both the fields are mandatory. I
select a value in the dropdown but do not enter anything in the textfield.
The ActionForm performs the validation and returns an ActionError. But when
i'm repopulating the screen i do not have all the dropdown values in my
FormBean (only the selected value is sent as part of request). How do i
handle this situation if i should not make any database calls from the JSP.
I'm sure that this is a standard problem and most of you guys would've faced
this. It would be great if someone can let me know what is the
right/approppriate way to handle this.
Thanks in advance,
Gana
