Referencing jsf list properties from backing beans

Referencing jsf list properties from backing beans

Referencing jsf list properties from backing beans

(OP)
Hi,

I've bound a list to a database table. I have a jsf table bound to the same table and want to update the display of the data in the table depending on the option chosen in the list. I've found a cracking tutorial to help with this but in the session bean I've tried the following code:

public void personIdDD_processValueChange(ValueChangeEvent event) {
    try {
       getSessionBean1().getTripRowSet().setObject(
         1, personIdDD.getSelected()); // <--Problem here
       tripDataProvider.refresh();
     } catch (Exception e) {
       error("Cannot switch to person " +
         personDataProvider.getValue(
         "PERSON.PERSONID"));
       log("Cannot switch to person " +
         personDataProvider.getValue(
         "PERSON.PERSONID"), e);
    }
}

this method is trying to reference the personIdDD UIComponent directly. It is not bound to a field in the session bean (which would allow the reference to work) instead it is trying to reference the id directly from the jsp page. I'm not sure how to work around this, maybe I'm missing something obvious. The full tutorial for this is at

Any ideas?
