Howard M. Lewis Ship commented on TAPESTRY-1645:
------------------------------------------------
This is doable, but there is the issue about whether any of the components
enclosed by the Grid need to find the Grid instance in a later action request.
Environmentals are intended largely for rendering. In an action event, the
component is triggered directly, and there's no way to setup the environment.
This is why GridPager and GridColumns components have an explciit parameter to
connect to their encloding Grid, rather than an Environmental.
