go - revel's .flash and .error -

-

i installed booking app , build small app myself , both suffer inability of displaying flash errors shown here: https://github.com/revel/revel/blob/master/samples/booking/app/views/hotels/settings.html

the example view use in own app https://gist.github.com/daemonfire300/10581488 , iterating on .error works fine.

am missing something?

i wrote controller (please note used default app instead of usercontroller use in example):

type user struct {     username string     password string     email    string }  func (c app) register(user user) revel.result {     c.validation.required(user.username).message("missing username")     c.validation.required(user.password).message("missing password")     c.validation.required(user.email).message("missing email")     if c.validation.haserrors() {         c.validation.keep()         c.flashparams()     }     return c.redirect(app.index) }

when miss field on form (for example password), errors , previous fields' values restored, as shown here.
