I think I found one solution, what I did was to add the normal textfield
an AjaxFormComponentUpdatingBehavior associated to the onchange event. In the
code of onUpdate() I add an AttributeModifier that replaces the value of the
"value" attribute, then I replace the textfield in the form and use
target.addComponent(form, "form") to replace the form in the page, so when the
autocomplete textfield receives input the getElementById() can get the value.
At least is working, any comments are welcome.

it, but maybe if the first textfield sent its value and a serverside reference
hold it until the autocomplete field received the input and used this value?.

it doesnt work because the url is cached by the autocomplete script. we need to
think of another way.

I'm including a striped down code version of the problem. It contains an ant
build file whose directory definition should be changed, but apart from that I
think it could run without trouble, I haven't included style file so the
autocomplete box is transparent but it's working. If you take a look at the
VendorsAutocompleteBehaviour.java file, you'll see how the parameter is being
recovered using document.getElementById.
Thanks,
Jaime.

so that i can see the problem in runtime. what you have sent over does not
compile when i drop it into quickstart as it contains your app-specific

though it's not complete quickstart, maybe it can help to show the context. The
zip contains the page ( index.html, Index.java) and the autocomplete field and
behaviour. Hope it can help to find what's going on.
Thanks again,

(returned by getMarkupId() and generated by setOutputMarkup(true)).
This is the generated html :
<input value="" maxlength="16" type="text" class="tipo" size="12"
name="numero" id="numero">
<script> document.getElementById('numero').focus();</script>
The strange thing is that if I set the value of the field in the model so the
page loads with the normal field populated, then the code works returning the
value I set in the page (in Java).
It seems that the javascript is not getting the input typed in the field.

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.

Jaime De La Jara <[EMAIL PROTECTED]> wrote: 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.
Jaime.
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?

On 3/26/07, Jaime De La Jara < [EMAIL PROTECTED]> wrote: Basically what I
need 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.
