blockUI not work when use blockUI first load

[gaojianzhuang]

angular.module('myApp').controller('MyController', function($scope, blockUI) { // A function called from user interface, which performs an async operation. $scope.onSave = function(item) {

// Block the user interface
blockUI.start();

// Perform the async operation    
item.$save(function() {

  // Unblock the user interface
  blockUI.stop();
});

}; });

I used this scripts in my project. It doesn't work. I debug the code, find the "blockCount" default value is 1. However, I debug the official demo, the "blockCount" default value is 0. I don't know why.

BTW, my project has multiple module, they all will reference the block UI module. Is it the reason?
