Hi Bas,
Okay. Let me explain it more.
So far I used converters for date fields like this which has been worked
fine.
DateConverter dc = new DateConverter(true) {
@Override
public String getDatePattern(Locale locale) {
return "yyyy.MM.dd";
}
@Override
protected DateTimeFormatter getFormat(Locale locale) {
DateTimeFormatter fm =
DateTimeFormat.forPattern("yyyy.MM.dd");
return fm;
}
};
DateTextField form_tol = (DateTextField) new
DateTextField("fDate", dc) {
@Override
public boolean isEnabled() {
return status == null;
}
};
In wicket 9 I changed this to
DateTextField from = new DateTextField("fDate", new
PropertyModel(model,"fDate"),"yyyy.MM.dd");
Now if I run my quickstart I get the following error msg:
* 'fDate' is not Date type.
I have no idea how to get rid of it.
I think all the validators refactoring is at the second place right now.
TIA,
Sandor

Hi Sandor,
In your QuickStart (Homepage.java) I see that you are accessing the raw
field value.
Since you are using an input of type=“date”, the value will always have a
specific format:
https://developer.mozilla.org/en-US/docs/Web/HTML/Date_and_time_formats#date_strings
https://www.w3.org/TR/2011/WD-html-markup-20110405/input.date.html (RFC
3339 “full-date”)
The standard format is yyyy-mm-dd (or yyyy-MM-dd in java).
You shouldn’t need to access the underlying String value of the date field.
Instead, create a validator that implements IValidator<Date> and in its
#validate method access validatable.getValue() to get the Date provided by
the user.
So you don’t need to worry about converting the date yourself from String
to Date. You can simply run validations on the Date directly.
Met vriendelijke groet,
Kind regards,
Bas Gooren

Hi Bas,
Sorry for the delay..
I use org.apache.wicket.extensions.markup.html.form.DateTextField in my
project
Meanwhile I figured out that the problem probaly is not with pattern but
the Date field itself.
I created a quickstart for the better undestanding.

Thank you.

Hi Sandor,
Which DateTextField are you using? The one from wicket-extensions or
wicketstuff?
In general I’m not sure I follow: since both variations of DateTextField
have a model type Date, any validator will receive a Date.
So can you explain (or perhaps show some code) how exactly you are getting
a string in your validator?
Met vriendelijke groet,
Kind regards,

Hi,
At the moment I try to migrate my 7.x project to 9.20.0 and stumbled on
a problem using DateTextField.
However I pass date pattern to my fields DateTextField tol = new
DateTextField("from", model, "yyyy.MM.dd");
when I validate them they alway get their value back in DateFormat.SHORT
according to my language settings.
Thus all of my validators based on this pattern will fail.
So far I used DateConverter and as I realized it's not necessary anymore
becase I can pass pattern as a parameter.
So please let me know which is the proper way to use this component.
TIA,
Regards, Sandor
