How to force user to select from AutoComplete choices
hello, I've an autocomplete textfield (this one: com.googlecode.wicket.jquery.ui.form.autocomplete.AutoCompleteTextField) and I'd like to restrict users to select one of the values presented in its choices. As it is, you can also input values that are not in the choices. Is there an easy way to do this ?

Re: How to force user to select from AutoComplete choices
Hi Heikki,
Basically the AutoCompleteTextField is a TextField, so you can cannot
restrict - strictly speaking - the user choice like you can do with a
DropDownChoice/DropDownList for instance...
However...
If the ACTF choice list is *type of String*, you can validate the user
choice, and report an error if the choice is not part of the list:
form.add(autocomplete.setRequired(true).add(new
IValidatorString() {
private static final long serialVersionUID = 1L;
@Override
public void validate(IValidatableString validatable) {
//TODO: customize the validation process here:
if (!MY_LIST.contains(validatable.getValue())) {
validatable.error(new ValidationError(not a valid
choice!));
}
}
}));
Second option: If the ACTF choice list is *type of beans*, then you can
check whether the modelobject is null in form#onSubmit. But as it is a
little bit late in the form processing (the components and form validation
already succeed) , prefer the option #1 if you can
Hope this helps,
Sebastien.

Re: How to force user to select from AutoComplete choices
thanks for your replies, @Igor : trying it, however when loading the page I get: TypeError: $(...).select2 is not a function. Can you give some instruction as how to wire things together? From the wicket-select2-examples, it is not obvious to me where any JS gets included. @Sebastien: sure, a validator can refuse input (doesn't even need to be a String I guess?), but that is also too late (after you already put in a free text value and submitted). I'm looking for a way to prevent unwanted input client-side; the validator will be there as last resort server-side. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-force-user-to-select-from-AutoComplete-choices-tp4658033p4658041.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: How to force user to select from AutoComplete choices
Hi, Just to answer... your answer: the ACTF can work either with String type or beans. Sure, the user enters a String but the ACTF is using the internal converter (the class type should have been provided in the ctor) to retrieve the bean reference back (from the previous choice list). About your use case, I think Igor's wicket-select2 is the best choice... Best regards, Sebastien.

Re: How to force user to select from AutoComplete choices
hi, the js loading issue was apparently due to having both my own and a select2-contributed jquery library in the same page. Solved. This select2 solution does exactly what I was looking for, thanks ! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-force-user-to-select-from-AutoComplete-choices-tp4658033p4658049.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
