Igor, unfortunely I haven't been able to use the solution proposed. I copied
and pasted the code for the getCallbackUrl method but it had a minor typo, but
after I corrected and reloaded the page with the autocomplete field the browser
(IE) throws a javascript error. The following works (using a hard code value) :
return super.getCallbackUrl() + "&limiter=1415";
but If I use this :
return super.getCallbackUrl() + "' + '&numeroFact=' +
document.getElementById('numero').value + '";
or
return super.getCallbackUrl() + "&numeroFact=' +
document.getElementById(\"numero\").value + '";
I get an "" when getting the parameter from the request.
The code generated in the page is the following :
new Wicket.AutoComplete('indexForm_proveedores',
'/adm-facturas/app?wicket:interface=:4:indexForm:proveedores:-1:IUnversionedBehaviorListener&wicket:behaviorId=1&wicket:ignoreIfNotActive=true&limiter='
+ document.getElementById('numero').value + '');
It seems the retrieval of the field is returning null !.
The field is defined as follows in the page :
<input wicket:id="numero" type="text" class="tipo" size="12">
and in the Java code :
add(new TextField("numero")
{
public String getMarkupId()
{
return "numero";
}
}.add(new NumeroFacturaValidador()).
add(StringValidator.maximumLength(12)).
setOutputMarkupId(true).add(new FieldFocusBehavior()));
I don't know what I'm doing wrong, any help would be greatly appreciated.

I'll try it right now. I agree that is an uncommon use case and it doesn't
deserve an api change and a custom solution is what is needed.

Igor Vaynberg <[EMAIL PROTECTED]> wrote: ok, this is a bit tricky but is def
doable. i dont think this is a very common usecase, so i dont think we will
create all the factories/etc for you to be able to do this out of the box
because in most cases it will just be api bloat.
that said, although not trivial it is still def very possible
start with extending the autocompletebehavior
override getcallbackurl and do something like
return
super.getcallbackurl()+"+'&limiter='+document.getelementbyid('someid').value");
so now whenever the url is invoked for the autocomplete it will also contain a
"limiter" param whose value will be the value of that textfield - make sure
someid is the id of that textfield.
then simply create your own component, or add the behavior directly to a
textfield, see AutoCompleteTextField source - its rather trivial.
now in your getchoices() you can do getrequest().getparameter("limiter") and
that will give you that extra value you need to filter
make sense?

is to narrow the possible choices of the autocomplete field, depending on the
value the user entered in the other field (which is a normal field).
This is a user requirement to simplify their data entry, in this case the
normal field is an invoice number and the autocomplete field corresponds to
the vendor name, so if the user enters invoice number 0189, and in the
autocomplete he types "E" the list displayed should show only the vendors whose
name start with an "E" and
have an invoice numbered 0189.
Thanks,
Jaime.

Hi, I have a form with some fields and a AutoCompleteTextField that is
working nice, however now I need to retrieve the value of a TextField from this
AutoCompleteTextField so I can restrict the values shown for autocompletion. Is
this possible?
umm...isnt that what the autocomplete is for? you are in control of the
choices, so why would you need to further restrict them?
-igor
in the affirmative case, could you give me a hint?
Thanks,
Jaime.
