----------------------------------------
Aforementioned thread: http://markmail.org/message/5gax6ms2tx5o3jbh
For the time being, I've got a binding that does what I immediately need. I
think letting mixins act as filters as described though could be a very
powerful mechanism. I'm even envisioning a follow-up to expansions that would
make use of this, like so:
${someVar|newlines:mode=para|capitalize|truncate:max=400}
Obviously, another issue for another day and syntax subject to change. I'm
just trying to further define what I'd like to do.
> provide access to component parameters from within mixins

> Key: TAPESTRY-1764
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1764
> Project: Tapestry
> Issue Type: Improvement
> Components: tapestry-core
> Affects Versions: 5.0.6
> Reporter: Kristian Marinkovic
>
> A mixin can't access the parameters of a component because the Bindings
> property of the InternalComponentResourcesImpl class is private and the
> respective interface does not provide a access method.
> I was trying to create a mixin that would render only the value of a form
> element (without the tags) when it was in a certain state. There also might
> be use cases where mixins are used to collect data from the components they
> are attached and therefore also needs access to the components parameters.
