I've done a bit of tracing on this and tracked the problem down the
following code in dryml/template_handler.rb
class ActionView::Template
def render_with_dryml(view, local_assigns = {})
if handler == Dryml::TemplateHandler
render_dryml(view, local_assigns)
else
render_without_dryml(view, local_assigns)
end
end
alias_method_chain :render, :dryml
The weird thing is that handler == Dryml::TemplateHandler evaluates as true
on the first render, but evaluates to false on all subsequent renders -
even though, according to the debugger, the handler method returns
Dryml::TemplateHandler each time.
Even more confusing is that the debugger reckons that the expression
evaluates to false on the second render.
The only difference I can see is that as handler is memoized, the first
call calls the method whereas the second call returns the cached result.
However, the debugger says that the memoized value of handler is a class of
Dryml::TemplateHandler

Possibly it is something to do with my environment?
