Subject: Can not find variable in the current scope!

Hello,

when trying to add tracing output to an erb template I hit the following
issue when trying to find where variable ex_title comes from.

Tried to list all possible variables in the current scope, but there
simply does not exists:
<%= instance_variables.grep(/ex_title/) %>   # renders an empty array
<%= global_variables..grep(/ex_title/) %>    # renders an empty array
<%= local_variables..grep(/ex_title/) %>     # renders an empty array

<%= instance_variables.sort %>   # renders array with many elements
<%= global_variables.sort %>     # renders array with many elements
<%= local_variables.sort %>      # renders array with many elements

Whereas ex_title variable provably does exists:
<%= ex_title %>                  # renders value "Categories - Online
store"
<%= ex_title.class %>            # renders "String"
<%= ex_title.object_id %>        # renders "15825900"

Where else can be found if not in global, local or instance variables ?
