-----------------------------------------
Assignee: Howard M. Lewis Ship
> Parameter passing between components is not well explain
> --------------------------------------------------------
>
> Key: TAP5-502
> URL: https://issues.apache.org/jira/browse/TAP5-502
> Project: Tapestry 5
> Issue Type: Bug
> Components: documentation
> Affects Versions: 5.0.18
> Reporter: Francois Armand
> Assignee: Howard M. Lewis Ship
>
> It seem that the documentation for parameter is milseading.
> The way parameter are defined and passed between a parent component and its
> child use to be really well explained (I think it was in the "Parameter"
> page, but I'm not sure). It seems that the introduction text which use to
> deal with the concept is no more in the Parameter documentation, what leads
> to really big miscomprehension from user.
> It would be really great to add again something about that at the beginning
> of the parameter page (before the loop example).
> That is the text in the T5 refcard on that topic, which seems quite good:
> ===
> A page binds the parameters of its child components. For example, a TextField
> properties
> component's value parameter is bound to a property, or property expression,
> indicating what object property it will
> read (when rendering) or update (when the containing form is submitted).
> ===
> And there used to be something about parameter being a conduit, both read and
> write, between a component and it's container that was quite nice too.
