Re: Using Variable as a List name

What I want to say is that, "argList1" contains the menu names:

List argList1 = new ArrayList();
argList1.add(menu1);
argList1.add(menu2);

And "argList2, argList3" contains the subMenus of "menu1, menu2"
respectively. (This will be done while populating "argList1") It will look
like as follows:

// subMenus of menu1
List argList2 = new ArrayList();
argList2.add(subMenu1);
argList2.add(subMenu2);
argList2.add(subMenu3);

// subMenus of menu2
List argList3 = new ArrayList();
argList3.add(subMenu4);
argList3.add(subMenu5);
argList3.add(subMenu6);

I am passing HashMap "root" as the argument for by freemarker template by
setting "argList1, menu1, menu2" keys.

HashMap root = new HashMap();
root.put("argList1",argList1);
root.put("menu1",argList2);
root.put("menu2",argList3);

Now the .ftl have an outer loop for "argList1" (for main menus) and inner
loop (for their subMenus). Another thing is that I doesn't know the the menu
names (i.e. menu1, menu2) while rendering my subMenus. I have to get these
menu names from the "argList1" and use them as a list to access
"root.put("menu1",argList2) or root.put("menu2",argList3)"

Doing this <#foreach subMenu in .vars[menu]> gives the following Error
"freemarker.core.InvalidReferenceException: Expression .vars[menu] is
undefined"



OR can someone suggest a better way to render these subMenus. I also cannot
able to use 2D Arrays in ftl's.
