The problem is that you must give action link something
to identify your object.
in the page you mentioned you have only one instance of
the MatchInfo component that get's rendered multiple times with different
data.
So when your action is called, you have the last element passed as
parameter.
you shoud link it like this:
<t:actionlink t:id="changedMind" context="match.id">Changed Your
Mind</t:actionlink>
public void onActionFromChangedMind(Long id)
{
//load match from database by the id
System.out.println(match.getName());
}
-----------------------------------------------------------------------------------------------------
if in you AppModule you make following TypeCoercers :
String->DateeeMatch
and
DateeeMatch -> String
above code can look like this:
<t:actionlink t:id="changedMind" context="match">Changed Your
Mind</t:actionlink>
public void onActionFromChangedMind(DateeeMatch match)
{
//load match from database by the id
System.out.println(match.getName());
}
