Hi Simon,
Actually i'm using an a4j ajax functionallity. I've a table and an onchange
event on a textarea fire this onchange method:
public String change() {
HashSet<Integer> keys = new HashSet<Integer>();
int rowKey = getRepeater().getRowIndex();
keys.add(rowKey);
setKeys(keys);
inputCountry.processValidators(FacesContext.getCurrentInstance());
inputCountry.processUpdates(FacesContext.getCurrentInstance());
//TO-DO catch the becking object
}
So I end up in the situation where i've a "reference" (inputCountry) to the
modified inputTextArea and the
inputCountry.processUpdates(FacesContext.getCurrentInstance())
is able to update the property of the object in the array list. What I would
like is to get only the updated object to do some business logic work
without have to take the whole list
Thanks
