RE: EL & Maps

Enrique   Rick Gruber-Riemer wrote I definitively can confirm that Maps are supported - as I am using them with MyFaces 1.1.1   So Your JSP code should be   JSP EL _expression_ --> <t:dataTable value="#{puntuacionesBean.listasPuntuaciones }"/> which will invoke you bean code   public Map getListasPuntuaciones()   the value attribute (in t:dataTable) expects to be returned an object containing what will be your Rows of data   you ONLY need puntuacionesBean.listasPuntuaciones['2'] when you are trying to make your code invoke Map.get(Key) – if you need to use this you must make sure that the ‘2’ value is compatible with you Key object type   Stefan Maric | IT & Professional Services | BT Global Services | E: [EMAIL PROTECTED]  |  www.bt.com/globalservices   This electronic message contains information from British Telecommunications plc, which may be privileged or confidential.  The information is intended for use only by the individual(s) or entity named above.  If you are not the intended recipient, be aware that any disclosure, copying, distribution or use of the contents of this information is strictly prohibited.  If you have received this electronic message in error, please notify me by telephone or email (to the number or email address above) immediately.   Activity and use of the British Telecommunications plc e-mail system is monitored to secure its effective operation and for other lawful business purposes.

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 Rick Enrique Medina wrote: 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 -----Ursprüngliche Nachricht----- Von: Rick Gruber-Riemer [mailto:[EMAIL PROTECTED] ] Gesendet: Mittwoch, 2.
