As far as I can tell: you do not need ".value". You would need
map[key].field if the entry associated with the key is an object of
which you want to have the value of a field and not the object (e.g. a
String) itself.
Besides: There is no need for a setter if all you are doing is to read
from the map

Hi,
Yes I have both a getter for the map and a setter, which returns the
whole map.
Let's put my example:
JSP EL _expression_ --> <t:dataTable
value="#{puntuacionesBean.listasPuntuaciones['2'].value}"/>
Bean PuntuacionesBean -->
public Map getListasPuntuaciones()
{
// Imagin something like...
this.puntuacionesMap = new HashMap();
this.puntuacionesMap.put(new Integer(2), //someValue);
return puntuacionesMap;
}
public void setListasPuntuaciones(Map listasPuntuaciones)
{
this.listasPuntuaciones = listasPuntuaciones;
}
If I debug the code, the value binding returns null when getting the
value for the data table...
2005/11/2, Stefan Gesigora <[EMAIL PROTECTED]>:
Hi
Enrique,
you always need a getter and a setter method for the map.
Then you can use it with the EL in this way:
<h:inputText binding="#{test1Bean.map['t3']}"/>
If you use a list:
<h:inputText binding="#{test1Bean.list[1]}"/>
regards,
Stefan

Betreff: Re: EL & Maps
Hi
I definitively can confirm that Maps are supported - as I am using them
with MyFaces 1.1.1. Maybe you could elaborate a bit more ...
