Best approach to implement date dropdown
Hi
I am using Struts with Velocity as a replacement to JSP. I would like
to implement a date drop down list and love to hear your opinions on
the best way to implement it.
I like to have something like these on my ActionForms and use
ValidatorPlugin to validate the data:
[MM] [DD] [YYYY]
Or
>From [MM] [DD] [YYYY] to [MM] [DD] [YYYY]
I am planning to create two DynaValidatorForm: DateForm and
TimePeriodForm. Something like these:
DateForm {
Integer month;
Integer day;
Integer year;
}
TimePeriodForm {
DateForm start = new DateForm();
DateForm end = new DateForm();
}
So in my form, I can call them as timeperiod.start.month,
timeperiod.start.day and timeperiod.start.year, etc...
My concern is how to validate the data and make sure the start date
less than the end date.
I am looking forward to hear from you.
Thanks,
Ben

If your users are happy with the separate drop-downs for month, date,
and year than this approach allows the greatest control. However, since
the data is spread between multiple input fields, I think you will find
that it is easier to implement validate() yourself instead of trying to
use the Validator.
Certainly ensuring that the to date is greater than the from date is a
custom validation.
You might want to look into using a Calendar control. This can give you
the best of both worlds; controlled input but still convenient for the
end-user. I have had good luck with

Hi Carlos
I was meant to say ValidatorForm.
Cheers

Good mornign Ben...
I've settled for the quick & easy solution: there are lots of JavaScript
scripts that can handle date selection boxes :^) The thing is I don't know
much about Velocity :^(
As for the validation, with the Validator Framework (VF) you can validate
that the dates entered/selected by the user are valid dates (i.e. dates in a
specific format [pattern]) You can also combine the VF with ValidatorForm's
validate() method to check date ranges or any other complex date validation.
I'm not shure why you'd want to use a "date bean" in the form of a
DynaValidatorForm, maybe you could comment more on your intended solution...
Regards,
Carlos
