RE: Accepting multiple date masks with the date validator
IIOC, the only way you can do this with the stock validator is to use mask rather than date as the validator. Then, you can use a regex to dictate your mask. I'll warn you though, if you use a regular expression it's going to be VERY long because it will also need to validate that the date entered is valid. Additionally, the stock date validator accepts dates like 30 FEB and just rolls it to the appropriate March date. Here's the REGEX we use (note that the regex is all on one line with no spaces: var var-namemask/var-name var-value^(((0?[1-9]|1[012])/(0?[1-9]|1\d|2[0-8])|(0?[13456789]|1[012])/(2 9|30)|(0?[13578]|1[02])/31)/(20)((0[6-9])|(10))|0?2/29/((20)(0[48])))$/var- value /var Alternatively, you can override the validate method in your ValidatorForm and do it yourself - which given your requirements, sounds like the easier of the two options. -Adam -Original Message- From: Scott Van Wart [mailto:[EMAIL PROTECTED] Sent: Wednesday, 02 August 2006 14:59 To: user@struts.apache.org Subject: Accepting multiple date masks with the date validator I have a requirement in my project that I be able to accept two different date masks. One with slashes (thus, 10 characters) and one without (8 digits). Is there any way to do this with the stock date validator, or do I need to roll my own wrapper?

Holy lipton that's nuts. I think I'll see what's behind door number 3:
public void setDate( String date )
{
this.date = translateDate( date ); // where translateDate inserts the
slashes if necessary
}
So I can use the date validator with no problems, and when the client
submits the form, they get back a slash-separated date in the input field.
Thanks for the help :)

Re: Accepting multiple date masks with the date validator
HAHA! I would have done the same thing. I don't want things like that
(regexp) creeping around my application, even if I do only have to touch it
once. Ech! shivers

Re: Accepting multiple date masks with the date validator
Heh. Regular Expressions aren't for everyone - I happen to work w/ two
engineers who live and die by them.
In your bean setter for the date, I'd make sure no exceptions could be
thrown, or handle them - the code I took over from an engineer we had
that left had this issue and it took me almost a week to track down what
was going on between the validator and his code.

Yeah, essentially I'm covering all the bases (null pointers, index out of bounds, etc.) so no RuntimeExceptions can be thrown either. If anything doesn't look right to the translation method, it simply returns the original. I DO like regular expressions, but feel that a lot of people go overboard and use them for things they shouldn't be used for :). - Scott - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
