Disable/enable context menu for jQuery Dynatree not working

Question

I am using the jQuery dynatree along with the context menu found here. The issue I'm having is that I can't get the enable/disable of the context menu or individual items in the menu to work. The plugin says I should be able to do this:

$("#contextMenu").enableContextMenu();

but that doesn't work for me. Here's the menu:

 <!-- Definition of context menu -->
 <div id="contextMenu">
     <ul id="myMenu" class="contextMenu">
       <li class="resubmit"><a href="#resubmit">Resend</a></li>
     </ul>
 </div>

The menu shows and works fine if I don't put any enable/disable, but there are cases where the menu item is not available so I need to be able to control its state. If I put in the enable/disable, the manu doesn't show at all.

Can anyone share how they got this to work?

UPDATE: I can only get the menu to show if I remove the DIV above. Then it will show, but enable/disable using "myMenu" does nothing...

Answer 1

I couldn't disable the menu itself, so I had to handle it after the item is selected:

switch( action ) 
{
    case "resubmit":
        //-- show verify dialog
      var selectedNode = $("#tree").dynatree("getActiveNode");
      if(selectedNode == null) 
           break;
      var parentTitle = selectedNode.parent.data.title;
      if( parentTitle == "Error" || parentTitle == "To Lab" || parentTitle == "From Lab" )
            $('#dialog-confirm').dialog('open');
             break;
    default:
             alert("Invalid action '" + action + "' to node " + node);
}

I just check that the proper type node is selected to be able to take the action (look at parent, which is the containing folder).
