Autocomplete prefix
Hi all.
I'm testing the autocomplete component, but I don't understand how prefix (used as search input) is passed to the bean.
Here my code:

</h:head>
<h:body>
<rich:panel style="height:500px;overflow:auto">
<rich:autocomplete mode="cachedAjax" tokens=", " minChars="1"
autofill="false"
autocompleteMethod="#{comuniBean.autocomplete}" />
</rich:panel>
</h:body>
</html>
Bean:
package it.ubi.test.bean;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
public class ComuniBean implements Serializable{
private static final long serialVersionUID = 1L;
private ArrayList<String> comuniList;
public void init() {
comuniList = new ArrayList<String>();
comuniList.add("Brescia (BS)");
comuniList.add("Milano (MI)");
comuniList.add("Bergamo (BG)");
}
public List<String> autocomplete(String prefix) {
ArrayList<String> result = new ArrayList<String>();
if ((prefix == null) || (prefix.length() == 0)) {
comuniList = new ArrayList<String>();
comuniList.add("Brescia (BS)");
comuniList.add("Milano (MI)");
comuniList.add("Bergamo (BG)");
result = comuniList;
} else {
Iterator<String> iterator = comuniList.iterator();
while (iterator.hasNext()) {
String elem = iterator.next();
if ((elem.toLowerCase().indexOf(prefix.toLowerCase()) == 0)
|| "".equals(prefix)) {
result.add(elem);
}
}
}
return result;
}
}
I copied autocomplete example.
If I debug this code, the "prefix" variable is always null.
Bean is correctly mapped, tested using the autocompleteList param.
Many thanks,
Enrico
