Hi,

I will try to simplify my problem as much as possible. In my case the  
auto generated, so I do not know the variable name before. Maybe this is  
better question to devel, but will try you guys.

Consider to have values, doesn't matter in which scope

vars does not do recursive templating, just use {{var2}}

thanks, but I can't. The variable name is constructed ...

That means I need to change the way how work with variables.
