Subject [jira] [Created] (TAP5-1846) Documentation for Mixins and Informal Parameters is not correct.
Date Mon, 13 Feb 2012 16:26:59 GMT
Documentation for Mixins and Informal Parameters is not correct.
----------------------------------------------------------------

                 Key: TAP5-1846
                 URL: https://issues.apache.org/jira/browse/TAP5-1846
             Project: Tapestry 5
          Issue Type: Bug
          Components: documentation
    Affects Versions: 5.3
            Reporter: Barry Books
            Priority: Minor


The current documentation states:

If the component and a Mixin both define a parameter with the same name, then the component
wins: the component's parameter will be bound, and the Mixin's parameter will be unbound.

Alternately, you may prefix the name of the parameter with the unqualified name of the Mixin
class

It's not clear from this statement what happens to unqualified informal parameters when the
component and Mixins support informal parameters but it appears the current implementation
will never assign any informal parameters to a component if you add a Mixin that supports
informal parameters. Please add something like the following to the documentation:

In the case of informal parameters without a qualifier the Mixin that supports informal parameters
will receive the all the unqualified informal parameters. If more than one Mixin supports
informal parameters the results are undefined.

Thanks
