Error messages targetted to the user are kept in the session and are manipulated with the [error] tag. Warnings are manipulated with the [warnings] tag.

This model has the following flaws:

  • By default, the errors are retained in the session. This utterly confuses the user.

  • [error all=1] displays errors in a all but random order. Errors should be displayed in the same order as they appear in the corresponding form.

  • Different semantics of [error] and [warnings].
