Question

Suddenly the scripts I was working on, are all stating this error when I use a click handler: Error Encountered: An unexpected error occurred

For example :

var clickHandlerColapse = app.createServerClickHandler("respondColapse");
upButton.addClickHandler(clickHandlerColapse);<br>
clickHandlerColapse.addCallbackElement(verPanel);

Calling the function:

function respondColapse(e) {
    var app = UiApp.getActiveApplication();
    app.getElementById('abpanel').setVisible(false);
    return app.close();
}

Any ideas what could cause this or why?

try this simple code :

function buttontest() {
  var app = UiApp.createApplication().setHeight('50').setWidth('150');
  app.setTitle("test this button");
  var panel = app.createFlowPanel()
  var quit = app.createButton('quit');
  app.add(panel.add(quit));

  var QHandler = app.createServerHandler("quit");
  quit.addClickHandler(QHandler);

  var doc = SpreadsheetApp.getActive();
  doc.show(app);
}
//
function quit(){
  var app = UiApp.getActiveApplication();
  app.close()
  return app;
  }

On Chrome and safari (mac) It causes an error ‘An unexpected error occurred’
