JSF&；对话框关闭后的primefaces背景按钮不'；行不通

我有一个打开对话框的按钮：

<p:commandButton id="addbutton" value="Новая контрольная точка" oncomplete="dlg_add.show();" rendered="#{controlPointBean.selectedSubject != null}"/>

---

是否存在JavaScript错误？症状听起来很像，也许是这个问题？是的，是JS错误。已删除向导。重置（）；从oncomplete标记开始，它工作正常。但现在，当我单击按钮时，向导并没有从头开始。@user2851836-如何？请贴出答案
