Re: Preventing disallowed items from being added to menu

I had the same need and basically solved the problem by extending the CoolMenuDisplayer and overridding the buildMenuString() method.

Here's the code I used, but we modified a number of other things in this class, so I don't know if it will work on it's own. If not, let me know and I'll send the entire class.

	protected void buildMenuString(MenuComponent menu, StringBuffer sb,
			boolean allowed) {		
		if (allowed) {
			sb.append(menuMessage.format(getArgs(menu, allowed)));
			sb.append(")\n");
			
			MenuComponent[] subMenus = menu.getMenuComponents();

			if (subMenus.length > 0) {
				for (int i = 0; i < subMenus.length; i++) {
					buildMenuString(subMenus[i], sb,
							(allowed) ? isAllowed(subMenus[i]) : allowed);
				}
			}
		}
		else {
			sb.append("");
		}
	}
