TypeError: Cannot read property 'getContainer' of undefined

1633 | var group = subProcess.getContainer();
652 | cmdPlugin._deleteSubProcessNode(graph, i);
646 | selectedItems.forEach(function (i) {
528 | this.method && (isString(this.method) ? graphthis.method : this.method(graph));
557 | cmd.execute(graph);
503 | _this.execute(name, graph, cfg);
910 | graph.commandEnable(cmdName) && graph.executeCommand(cmdName);

1.这错误是模块原有的吗 ？(删除节点时出现)

2.图片改文字可行，只是拖拽时默认是选中文字，如果先选中文字，再拖动是可以的，如下图GIF：

1、你每次删除的时候都这样吗？把错误信息粘全一些，你用了子节点吗？
2、你把css的属性设置上user-select:none就选不中文字了，

[zhuifeng00001]

user-select:none
1.是的，每次都会崩溃。代码在下面。
2.加上这个样式，文字是不能被选中了，但同时，也不能拖拽了。我像蚂蚁啃骨头啊，哈哈

你是删除的子流程节点吗？

[zhuifeng00001]

你是删除的子流程节点吗？

如果与删除顺序有关，那可能就是了。
从后向前删除，随意删除，都操作过。错误提示也一样。

[ahayaSKBINCN]

这个问题我也遇到过!
在错误那行添加个if判断下子节点是否存在;这个是重复删除了

[guozhaolong]

本来想在新版本一起修复，目前新版本g6还存在拖拽bug，只能先简单改一下这个bug了
