获取当前流程，流程记录的方法

波斯大香蕉

假如我有一个列表，选中了某一列，然后点击流程图或者流程记录的按钮，需要用什么去获取？
var data = this.comp("sqData").getCurrentRowID();
var sq = this.comp("sqProcess");
sq.showChart(null, null, data,true);

例如流程图，我这样获取，会获取不到，报错提示如下：

        // 获取流程图
        Model.prototype.button1Click = function(event) {
                var data = this.comp("sqData").getCurrentRowID();
                var sq = this.comp("sqProcess");
