Nesting list tags breaks the name_index

[Ben Rometsch]

If you have two nested lists, e.g.:

#{list list1, as:'list1'}
  ${name_index}

  #{list list2, as:'list2'}
    ${name_index}
  #{/list}
#{/list}

It appears that the name_index context is not specific to the nested list, and so it is incremented in both the outer and inner list.

What is ${name_index} ? It should be ${list1_index} and ${list2_index}

For the inner loop, this works, but the outer loop is still showing the incorrect value...

I think I found a fix to this. In play.templates.InlineTags there's a loop variable _i which should be _{$index}_i.

This patch is tested and really really works.

A different example...

#{list items:0..5, as:'a'}
  ${a_index}
#{/list}

outputs: 1 2 3 4 5 6
(as expected)

However,

#{list items:0..5, as:'a'}
  ${a_index}
  #{list items:0..5, as:'b'}#{/list}
#{/list}

outputs:
1 8 8 8 8 8

The mere presence of a nested list breaks a_index.

Leo, so did my patch help?
