inputCalendar validator

["Whitmire, Tracy Carroll" <tc...@sandia.gov>]

Hi,

I'm using t:inputCalendar and have a question I'm sure someone has
already addressed.  But a google search was futile.

If a user decides to enter the input in manually .... What's the best
way to validate this input?

I have a user who loves to enter the date as MM/dd/YY ignoring the help
text

But the expected is MM/dd/yyyy

So when he enters 12/01/06 ....

It gets entered into the database as Dec, 01, 0006

Thanks for your help,

tc

Might not be much of help, but I implemented a rather complicated
converter ... well not that complicated, just uses tons of simple date
formats ... to allow the user to enter virtually any date. e.g.
mm/dd/yyyy, mm/dd/yy, mm/dd or just dd for the first two cases I use the
fact that you can have a DateFormat m/d/y and java is smart enough to
parse it right.

        SimpleDateFormat sdf = new SimpleDateFormat("M/d/y", Locale.US);
        System.err.println(sdf.parse("12/01/06"));
        System.err.println(sdf.parse("12/01/2006"));

With some tricky string operations you can create the patterns in a
locale sensitive way.

Ciao,
Mario

I use the following code to do that (just write a validator like u are 
used to it in jsf)

<t:inputCalendar id="birthDate"
value="#{member.birthDate}"
renderAsPopup="true"
popupTodayString="#{messages['popup_today_string']}"
popupWeekString="#{messages['popup_week_string']}"
popupDateFormat="dd.MM.yyyy"
helpText="DD.MM.YYYY"
required="true"
validator="#{validators.birthDateValidator.validate}"/>

where validators is a bean and returns a new Validator Object (u can 
play around a bit and register the validator in faces-config.xml but i 
choosed this approach).
Just write a validator like in jsf.

public class BirthDateValidator implements Validator {


public void validate(FacesContext fc, UIComponent uic, Object o) {
//do validation here
}

}


thats it, i was suprised it works like i "expected"

Yaron,

I think you did not quite understand his scenario. The user is entering 
"MM/dd/YY" format (by hand, not clicking) instead of "MM/dd/yyyy". A 
validator could easily detect that the year entered is too short, and 
send a message stating such back to the user.

Now in the case of MM/dd being confused with dd/MM.... there, you would 
really be in trouble. :)

Don't you sometimes wish you could replace some of your users :->

 

But seriously, your question does not seem to be a JSF related question,
if the user clicks a valid date you can not check (as far as I know)
what he thought when he entered it.

My workaround would be to switch the input to comboBox, then you don't
need any validation. In order to solve your problem, present the month
as names "Jan", "Feb" etc. while leaving the dates as numbers, that
should do the trick.

 

Good luck :->
