Validating multiple components as one
Hi to everybody!
My little problem is about validating multiple input fields as a single one.
So, I have three DoB fields (one for the day, one for the month and one
for the
year) that should be validated as a single date.
While using Wicket 1.5 we overwrote AjaxEventBehavior#getEventHandler() and
returned a custom made JavaScript that serialized the three fields like
this:
StringBuffer buffer = new StringBuffer("wicketAjaxPost('")
.append(this.getCallbackUrl()).append("', ");
for (String id : this.getInputIds()) {
buffer.append("wicketSerialize(Wicket.$('").append(id).append("')) + ");
}
buffer.setLength(buffer.length() - 3);
return buffer;
This worked pretty well. But I have to migrate the application to Wicket 6
and this doing does work anymore. As far as I understood the new Ajax-way,
it isn't possible anymore to provide a custom script like the one above. But
how can I restore the old behavior? Do I have to put the fields into a
form and
submit the whole form to validate it?
Thanks in advance!

Hi Martin,
thanks for your reply, it definitely made my day! I had to tweak the
snippet a little, because Wicket.Form.serialize() returns an array of
objects that does not really work out for the AJAX request. So I changed
the value expression into Wicket.$(id).value and that worked perfectly.
Thanks a lot!

Hi,
The new way is to use the dynamic extra parameters.
Each Ajax behavior and component has a method
#updateAjaxAttributes(AjaxRequestAttributes attributes) :
attributes.getDynamicExtraParameters().add("return [obj1, obj2, ...]").
Where objN are JavaScript objects like: {"name":
formComponent.getInputName(), "value":
Wicket.Form.serialize(Wicket.$('"+formComponent.getMarkupId()+"')) }
The above is a pseudo code but I hope you follow me.

Hi Sven,
unfortunately it would be a too great effort to change every usage of
those input fields (because they are inside a library and are used very
often). So I had to go along with Martin's suggestion. But anyway,
thanks for the quick reply!

Wrapping all three inputs in a form with an AjaxFormSubmitBehavior is the easiest solution.
Do you have any problems with it?
