Navigation plugin throws toLower exception rendering subItems
My question is how do i get the grails navigation plugin to show subItems?
I did a simple thing and added the following to top of my Controller:
class DummyController {
static navigation = [group: 'tabs',
title: 'dummy',
action: 'list',
subItems: ['create', 'save']
def create = {....
In main.gsp I added the following:
<head>
...
<nav:resources/>
</head>
<div开发者_运维技巧 id="menu">
<nav:render group="tabs"/><br/>
<nav:renderSubItems group="tabs"/>
</div>
Expecting this to work instead i get an exception:
Cannot invoke method toLowerCase() on null object
Jira has this bug filed and someone mentions adding:
if(!controllerName) return out
To the top of def renderSubItems function in NavigationTagLib.groovy which i have. It now no longer throws that error but my sub-menu items still dont display.
Any help on how to get the sub-menus displaying would be greatly appreicated Thanks
It seems it did work, when a menu item is selected the new page loads and shows 'create' and 'save' underneath on the new page.
I misunderstood and was expecting the subitems to appear before i clicked on the menu button, or if i hovered over the menu button. I wanted to use the YUI css and let nav plugin do the hardwork but this is not the style of menu im after. I wanted a more dynamic menu i.e. you hover over a menu item and it shows a dropdown of subitems allowing you to go directly to an action much like the YUI menubar.
