dragdrop事件禁用页面中的所有按钮

Question

我页面上的保存按钮的格式不同于p:tree，此按钮可以正常工作，直到您对树进行拖放，然后不仅是此按钮，还包括页面中的所有其他按钮将不再工作。 他们的onstart和oncomplete有效，但他们的listeners无效。

在拖放时：

public void treeOnDrop(TreeDragDropEvent event) {
    GaStructNode dropData = (GaStructNode) event.getDropNode().getData();
    GaStructNode dragData = (GaStructNode) event.getDragNode().getData();
    if(dragData != null) {
        dragData.setParent(dropData);
    }
}
