I have a data bound Grid. Changing the value of a cell fires the onItemCodeChanged(). I can store the index of each row as row's data. Is there a way to retrieve directly the index of the row?

	public void onItemCodeModified(InputEvent event) {
		Row row = (Row)event.getTarget().getParent();
		Integer index = (Integer)row.getValue();

Here is a simple snippet to get an idea.

ZUL code

<grid id="gridContacts" fixedLayout="true" vflex="true"  model="@{ yourmodel }" >
	<columns sizable="true">
		<column label="Code" width="100px" />
		<column label="First Name" width="200px" />
		<column label="Last Name" width="250px" />
		<column width="100px" />
		<row self="@{each='contact'}" value="@{ selectedContact }">
			<label value="@{ record.code }" />
		        <toolbarbutton label="@{ contact.firstname }" forward="onClick=onEditContact" />
		        <toolbarbutton label="@{ contact.lastname }" forward="onClick=onEditContact" />
			<button label="Delete Line" forward="onClick=onDeleteContact" />

The composer code

public void onEditContact(Event event) {
	Contact contact = getSelectedContact(event);
	edit the selected contact

public void onDeleteContact(Event event) {
	Contact contact = getSelectedContact(event);
	delete the selected contact

private Contact getSelectedContact(Event event) {
	if (event instanceof ForwardEvent) {
		ForwardEvent fwevent = (ForwardEvent)event;
		Event eventOrigin = fwevent.getOrigin();
		Row row = (Row) eventOrigin.getTarget().getParent();
		Contact selectedContact = (Contact) row.getValue();
		return selectedContact;
	return null;

Hope that helps
