Question

I have a script creating buttons in a table.
Each button is assigned to the same callback server function.
My question is how do I know which of these buttons triggered the server call?

Also is there a way of outputting a msgbox from the server script? When I try browser.msgBox, it gives an error saying that msgbox can’t be used in this context.

var clientDel = app.createServerHandler("delStudent").addCallbackElement(grid);
table.setWidget(t, 4, app.createButton("Delete", clientDel).setId("del1"));

function delStudent(e){
  var app = UiApp.getActiveApplication();
  e.
  return app;
}

Thanks,
C Singh.

1. simply e.parameter.source will return the ID of the widget that originates the handler function
2. You can use a label or a textBox that you create in your UI and set invisible. Then at any moment you can use getElementById(label_ID').setVisible(true) and put any text in it.

If you want it to appear at a specific position above all other widgets you can do that quite simply using setStyleAttributes, see this other post(server version) for further info and practical example
