Here''s my case: Using a link_to popup window to show a related help file of an element on a page. The problem: Window pops up perfectly, but refuses to carryover @instance variables in the controller that I referenced in the link_to command. The tests: - I have the right controller/class, because it renders a specific template, which is what it does. - I have the right template/view,
