    Hi all,

    trying to build a lightning component but flashing this error

    This page has an error. You might just need to refresh it.
    Assertion Failed!: Unknown controller action 'clickCreateCampingList' : undefined
    Failing descriptor: {ui$button$controller$press}

    clickCreateCampingList: function(component, event, helper) {

    // Simplistic error checking
    var validCampinglist = true;

    // Name must not be blank
    var nameField = component.find("expname");
    var expname = nameField.get("v.value");
    if ($A.util.isEmpty(expname)){
    validExpense = false;
    nameField.set("v.errors", [{message:" name can't be blank."}]);
    else {
    nameField.set("v.errors", null);

    // ... hint: more error checking here ...

    // If we pass error checking, do some real work
    // Create the new camping list
    var newitem = component.get("v.newitem");
    console.log("Create campingList: " + JSON.stringify(newitem));
    helper.createCampinglist(component, newitem);

    Hi Vikas,

    Your controller code seems to be fine, please check your page. Maybe there is some minor formatting error associated with the button you made on the page.
