a4j:ajax and multiple h:selectOneRadio elements
Hi all,
I use several h:selectOneRadio buttons to build a more user friendly selection interface, something like this
Selection and rerender works fine until I start an ajax call with a commandLink element. The linkElement starts the persistence process to dbin my case.
To avoid problems with logic steps behind I created a simple sample attached below. But same behaviour again.
After debugging the process I figure out that if link is clicked the setter of the pos property is called with value 0. Only exception: The last element is selected.

JAVA Bean
import java.io.Serializable;
import javax.faces.bean.ManagedBean;

@ManagedBean

public class Bean implements Serializable{
private static final long serialVersionUID = -9194353440404794097L;

public int getPos() {
return pos;
}
public void setPos(int pos) {
System.out.println("set pos:" + this.pos + " -> to -> " + pos);
this.pos = pos;
}
}
Output if not last element is selected
set pos:0 -> to -> 2 (1)
set pos:2 -> to -> 0
set pos:0 -> to -> 0
set pos:0 -> to -> 2
set pos:2 -> to -> 0
set pos:0 -> to -> 0
Output if last element is selected
set pos:0 -> to -> 4
set pos:4 -> to -> 0
set pos:0 -> to -> 0
set pos:0 -> to -> 0
set pos:0 -> to -> 0
set pos:0 -> to -> 4
What I do
Selected the third radio box (with value 2) and hit the link element. Why is the setter method called so often?
I expected: First click on the radio box: (1), then hit the ajax link element, maybe an additional line in console but not 5 with two which resets my value back to 0 ... In addition I posted the result if I select the last radio box (value 4) and hit the link. Works fine but also printed more lines out as excepted by me.

Would be grateful for each hint.
