Multiple Renders with Erubis

[probablykabari]

When using erubis (v 2.6.6 for me) the #form_for helper causes templates to render several times within the same layout.

I also met this problem with erb template.

Code:

 before
<% form_tag "/update" do %>
  # 'before' is rendered again here!
<% end %>
