Datetime-local input fields "send" empty values
Hello
I am still a user of Wicket 6.3. At this time upgrading is not possible
I created a DateTimeField as an extension of a TextField with
type="datetime-local"
It all works fine but any change or blur event at the WEB page level
tiggers a message to the server with an empy string (in other words date &
time are missing)
Can someone help me fixw this?
Regards
Christophe

Hi,
works fine when I've added your case to FormInput in wicket-examples.
You should create a quickstart showing your problem.
Have fun

Hello
Sorry for this late reply and a fairly confusing request. Let me try to
clarify
1) I still use Wicket 6.3 and wont be able to upgrade before 5 to 6 months
at least
2) I need a "HTML" date and time field that "uses" the "<input
type="datetime-local".../> HTML markup
3) I proceed as follows
a) I created a DateTime class that specializes TextField<String>and simply
checks that the corresponding
marup is indeed of type "input type="datetime-local""
This all works very well as Wicket does not complain and a pretty
datetime-local field is displayed on my
page.
b) I also need to receive the "value" of the datetime-local field when the
input field loses the focus ( DOM change event). So I created a
specilaization of AjaxFormComponentUpdatingBehavior whose method
onUpdate(..) is overloaded. The behavior is added to the Java component
This method is invoked when the date time markup loses the focus.
However the value is alswas an empty string.
I took a look at the message sent by the browser. It contains "an empty
string"
This is where I need your help.
i) Why is the value sent by the browser empy
ii) What do I do wrong / How can I fix it
Thank you very much
Christophe

Upgrade to a newer 6.x should be relative easy and it is highly recommended
because there are security related fixes!

What do you mean by "it all works fine" ?
In which case it works ?
What do you mean by change/blur event on *page level* ? Do you change
another text field in the page ? Because I am not sure when JS document can
trigger 'change' or 'blur' event, and why this would lead to a request to
the server.
Do you use Ajax behaviors somewhere ? For this date field ? Or for an
element that is parent of this date field ?
