描述

Using ui-grid with $viewContentLoaded throws the following error, because data and the grid are not initialized until the view is loaded. Ui-grid works fine but spits out this error,

angular.js:14525 TypeError: Cannot read property 'data' of undefined
    at new <anonymous> (ui-grid.js:3332)

Line in question:

      } else {
        if (angular.isString($scope.uiGrid.data)) {
          deregFunctions.push( $scope.$parent.$watchCollection($scope.uiGrid.data, dataWatchFunction) );
        } else {
...
      }

研究方向
Investigate the grid initialization in ui grid.js around line 3332. The error occurs because $scope.uiGrid.data is undefined when $viewContentLoaded fires. Ensure the data watcher is set up only after the grid is fully initialized, possibly by adding a null check or deferring to a later lifecycle event.
