I haven't looked at in in quite some time so probably worth looking at the source. So, $c->visit will run through the chain but also runs auto and end. $c->forward just executes the action w/o auto and end, but if the action is part of a chain and expand_action has not been run then it won't run the chain. Seem right? What's the reason that forward doesn't expand the chain and set the captures? -- Bill Moseley mose...@hank.org
