Primefaces: Tree node not selected when right clicking p:tree with selection and context menu

[jepsar]

I'm using PrimeFaces 5.3.

Setter for myBean.selectedNode is not invoked when right clicking the node in the example below.

<h:form id="mainForm">
    <p:tree value="#{myBean.root}" var="node"
            id="myTree" dynamic="true"
            selectionMode="single" selection="#{myBean.selectedNode}">
        <p:treeNode expandedIcon="ui-icon-folder-open" collapsedIcon="ui-icon-folder-collapsed"
                    type="myType">
            <h:outputText value="#{node}"/>
        </p:treeNode>
        <p:ajax event="select" listener="#{myBean.onNodeSelect}" />
    </p:tree>

    <p:contextMenu for="myTree">
        <p:menuitem action="#{myBean.addChild('new')}"
                    value="Add"
                    process="@this"
                    update=":mainForm:myTree"/>
    </p:contextMenu>
</h:form>

I'm still not sure if this is a bug or that I'm doing something wrong. Maybe it's related to the select listener, but without it it was also not working for me.

Anyhow, I was able to get it to work by replacing the tree's nodeRightClick function:

PrimeFaces.widget.BaseTree.prototype.nodeRightClick = function(e, a) {
    PrimeFaces.clearSelection();
    if ($(e.target).is(":not(.ui-tree-toggler)")) {
        var d = a.parent(), b = a.hasClass("ui-tree-selectable");
        if (b && this.cfg.selectionMode) {
            var c = this.isNodeSelected(d);
            if (!c) {
                if (this.isCheckboxSelection()) {
                    this.toggleCheckboxNode(d)
                } else {
                    this.unselectAllNodes();
                    // Fixed right click selecting
                    // original code: this.selectNode(d, true)
                    this.selectNode(d); // <-- Fix
                }
            }
            this.fireContextMenuEvent(d)
        }
    }
}

Please use contextMenu event.

I'm puzzled. I've checked the tree and contextMenu section of the documentation twice. What event should be used where?

@mertsincan

The 5.3 docs state:

Ajax Behavior Events

Tree provides various ajax behavior events.

| Event | Listener Parameter | Fired |
| --- | --- | --- |
| expand | org.primefaces.event.NodeExpandEvent | When a node is expanded. |
| collapse | org.primefaces.event.NodeCollapseEvent | When a node is collapsed. |
| select | org.primefaces.event.NodeSelectEvent | When a node is selected. |
| unselect | org.primefaces.event.NodeUnselectEvent | When a node is unselected. |

There is no contextMenu event in the docs but there is in the 5.3 code. Please create a new issue to update this as well as for the dragDrop event!!!

@jepsar: title is wrong... it is not 'selection' but 'ajax selection event'. that is the difference with the showcase. So your original title was right
