Passing more than one parameter on button click.

Pro Vaadiner

Hi,

We need a solution for one of the scenario where we have to pass more than one parameter on button click.

eg:
on clicking of employee instead of passing only emp_id now we need to pass emp_id,emp_name,emp_joindate,emp_salary

Normally we use event.getButton().getCaption() to fetch emp_id if it is just one parameter but in our case we are looking for a way to pass more than one parameter.

Thanks.

event.getButton().getCaption() to fetch emp_id

seems like a very bad way.

You could do something like this:

public class MyButtonListener implements Clicklistener{

private final Employee employee;

public MyButtonListener( Employee employee){
this.employee = employee;
}

.....


button.addListener(new MyClickListener(currentEmployee));

or if the employee is based on the current value in a table just to a Employee e = (Employee)table.getValue();

Danny Roest: or if the employee is based on the current value in a table just to a Employee e = (Employee)table.getValue();

... remembering that the value of the table is an item identifier and needs to be mapped to the Employee if not using a BeanItemContainer where the ID is the bean itself.
