Check box column trouble

Hi !

I am new with rich faces.
What i am trying to do now is adding a check box column to a rich extended data table, i did this adding a new column with a h:selectBooleanCheckbox inside of it.
The trouble is that i could not syncronize my check box selection with onRowClick event of table, an example could be when i deselect a table row the check box still remain selected. I am trying to solve this issue using just control components without using beans logic (i don't know if this is right).

Please if you know some tutorials explaning how to add a check box column to a extended data table or if there are some properties or events of table that could help me, give me a feed back.

Should i use some JavaScript to solve my trouble ?

<rich:extendedDataTable>
...
<rich:column width="8%" styleClass="checkBoxColum>
<h:selectBooleanCheckbox value="true" />
</rich:column>
...
</rich:extendedDataTable

Thanks,
Radu

Could anyone tell me an ideea how to do it without javascript ?

Please if you have an idea tell me.

Thanks,

I have no idea how to implement the synchronization without using bean logic.

I wrote some codes with bean logic. Hope it helpful. By the way, I am also newbie in RichFaces. If anything wrong with my codes, please help to advise.

Thanks!

import javax.faces.event.ActionEvent;

public class FriendBean {
	
	private List<Person> friends;
	private Person selectedFriend;
	private Set<Integer> rowsToUpdate;
	
	public FriendBean() {
		friends = Arrays.asList(new Person[] {
			new Person("David", "Gibb"),
			new Person("Steve", "Shaffer"),
			new Person("Monique", "Slack"),
			new Person("Kevin", "Happ"),
			new Person("Kimberly", "Herald"),
		});
		
		rowsToUpdate = new HashSet<Integer>();
	}

public List<Person> getFriends() {
		return friends;
	}

public void setFriends(List<Person> friends) {
		this.friends = friends;
	}
	
	public Person getSelectedFriend() {
		return selectedFriend;
	}

public void setSelectedFriend(Person selectedFriend) {
		this.selectedFriend = selectedFriend;
	}

public Set getRowsToUpdate() {
		return rowsToUpdate;
	}

public void setRowsToUpdate(Set rowsToUpdate) {
		this.rowsToUpdate = rowsToUpdate;
	}

public String rowClickAction() {
		System.out.println("Row clicked...");
		
		selectedFriend.setSelected(!selectedFriend.isSelected());
		
		rowsToUpdate.clear();
		rowsToUpdate.add(friends.indexOf(selectedFriend));
		
		return null;
	}

Hi !

Thanks a lot for your example, i studied it and is really meaningful also now i try to put it in practice in my application.

In my case i do not have a Boolean property on my object, and i could not to add one, so i create a new object witch has only that boolean property, also i don't have access to table's collection in java classes i must access them through spring web flow i guess.
Now i try to make the above changes.

Best regards,
Mircea
