your textfield doesnt have an id attribute defined, so
docuement.getelemetnbyid is not finding it

Sorry in the last post I had a type instead of limiter=1415 it should be
numFact=1415, I'm using "numFact" as the request variable.

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.

Absolutely !, thanks a lot Igor, 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.

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?
