Hi
While trying to answer your question, I came up with an example. Enjoy !!
public class RadioGroupDemo
{
@Property
@Persist
private List<User> users;
@SuppressWarnings("unused")
@Property
private User user;
@SuppressWarnings("unused")
@Property
@Persist(PersistenceConstants.FLASH)
private User selectedUser;
void onActivate()
{
if(users == null)
{
users = new ArrayList<User>();
users.add(new User("John", "New York"));
users.add(new User("Ramesh", "India"));
}
}
public ValueEncoder<User> getEncoder()
{
return new ValueEncoder<User>()
{
@Override
public String toClient(User user)
{
if(user == null)
{
return null;
}
return user.getName();
}
@Override
public User toValue(String clientValue)
{
for(User user : users)
{
if(user.getName().equals(clientValue))
{
return user;
}
}
return null;
}
};
}
}
<html xmlns:t='http://tapestry.apache.org/schema/tapestry_5_1_0.xsd'
xmlns:p='tapestry:parameter'>
<body>
<t:if test='selectedUser'>
You selected : ${selectedUser.name}
</t:if>
<form t:type='form'>
<div t:type='radioGroup' t:value='selectedUser' encoder='encoder'>
<div t:type='grid' source='users' t:add='select' row='user'>
<p:selectCell>
<input t:type='radio' type='radio' t:value='user' />
</p:selectCell>
</div>
</div>
<input type='submit' value='submit'/>
</form>
</body>
</html>
Remember, your object (User here) must has proper equals/hashcode
methods for selection to work
Regards
Taha
