Hi,
You are asking how to get the value of the 4 fields you are creating?
You can use a ValueExpression to map the data back to your List, or
anywhere else you would like. For example:
...
caja=new TextField();
caja.setId(dto.getId());
--> caja.setValueExpression("text", createVE("#{sessionBean.lista["
+ (idx++) + "].valor}"));
this.getGridPanel1().getChildren().add(caja);
...
private ValueExpression createVE(String exp) {
FacesContext facesCtx = FacesContext.getCurrentInstance();
return facesCtx.getApplication().getExpressionFactory().
createValueExpression(facesCtx.getELContext(), exp,
Object.class);
}
This will ensure the original object
(sessionBean.getLista().get(idx).setValor("<new value>")) is called.
However, you may want to use "binding" instead of "prerender".
"prerender" is not standard and may get invoked more than 1 time adding
too many fields to your page if it is refreshed.
I hope this helps you.
Good luck!
