I believe you have to supply the (_.None, _)
parameter for the index_html method to work.

You are ALMOST ALWAYS better off using the
<dtml-with ...> tag, something like

<dtml-with test2>
  <dtml-var a_something_inside_test2>
</dtml-with>

Or in the more general case of many layers

<dtml-with "FolderA.SubFolderB.SubSubFolderC.test2">
  <dtml-var methodA>
</dtml-with>

This pushes test2 onto the namespace stack. So
your methodA can still access objects inside
the SubSubFolderC.

------------------------------------------------

Use the dotted notation, e.g:

<dtml-var "F1.SF2.methodA(_.None, _)">

only if you don't need any objects from the
subfolder F1.SF2 during the call. Most of the
times, this is not what you want.
