thanks for your reply. i already solved the problem.
I missed something that it is said in this site:
http://getahead.ltd.uk/dwr/getstarted
"The new creator that we used above uses the public no-args constructor that
all JavaBeans must have"
the class ListaLocalidadSqlMapDao had this constructor:
public ListaLocalidadSqlMapDao(DaoManager daoManager){
super(daoManager);
}
so i created a new class "[b]Utilities.java[/b]":
public Utilities(){}
public List getListaLocalidadByIdMunicipio(Integer idMunicipio) throws
Exception{
...
} which returns a List of "Localidad" objects.
Then, on [b]dwr.xml[/b] :
<dwr>
<allow>
<convert converter="bean" match="es.di.domain.Localidad"/>
<create creator="new" javascript="Utilidades">
<param name="class" value="es.di.comun.Utilidades"/>
</create>
</allow>
</dwr>
And in the [b]JSP file:[/b]
<script type='text/javascript'
src='/pcmtmp/dwr/interface/Utilidades.js'></script>
function cambiaLocalidad() {
DWRUtil.removeAllOptions("localidades");
Utilidades.getListaLocalidadByIdMunicipio($("municipios").value,onCambiaLocalidad);
}
function onCambiaLocalidad(data) {
DWRUtil.addOptions("localidades",data,"id","nombre");
}
And as it is explained at this site: http://getahead.ltd.uk/dwr/browser/lists
i used the option: Array of objects (with differing option text and value):
DWRUtil.addOptions(selectid, data, prop) since [b]Localidad.java[/b] is:
public class Localidad {
private String id;
private String nombre;
...
}
