Found the solution:
Use the Suggest component instead.

The Autocompleter has issues anyway:

I am trying to implement a form that uses the Autocompleter component
http://tapestry.apache.org/tapestry4.1/components/dojo/autocompleter.html
I had a look at the TimeTracker demo application. It already works, but
I have one requirement that's differnet from the way the demo is
implemented:
The time trackler loads a complete list of objects from the DAO layer:
return new DefaultAutocompleteModel(getProjectDao().list(), "id",
"name");
In my application it is not possible to load the complete list from the
database. Instead the function in my DAO layer takes one argument:
List<Location> getManager().getLocations(String startWith);
So, how can I retrieve the user's input in the autocompleter field? For
example: the user enters "Aber", I retireve all Locations from the
database that start with "Aber" (Aberdeen), and then build a model.
I tried
@EventListener(
events = "onValueChanged",
targets = "locationChoose"
)
public void projectSelected(BrowserEvent event){
String selection = event.getMethodArguments().getString(0);
LOG.trace("Selected value = '" + selection + "'");
getBuilder().updateComponent("locationDescription");
}
but that return an identifier. The problem is: I don't need an
identifier for my call into the DAO layer, but the raw user's input...
Another question: I want my autocompleter to start async request only
when the user entered three or more chars. Is that possible?
