Re: Accessing a containing component parameter from within a
'child' component
I believe there is something mentioned on it on:
http://tapestry.apache.org/tapestry5/tapestry-core/guide/parameters.html#Inherited%20Parameter%20Bindings
with inherit: binding - however this doesn't work for me.

That should work.
With the inherit keyword you can forward parameters to sub-components,
like this example of a zebra Grid component:
public class MyGrid
{
@Parameter(required = true)
private GridDataSource source;
@Parameter
private BeanModel model;
@Parameter(defaultPrefix = TapestryConstants.
LITERAL_BINDING_PREFIX)
private String reorder;
@Component(inheritInformalParameters = true, parameters =
{ "rowClass=cycle:odd,even", "source=inherit:source",
"model=inherit:model", "reorder=inherit:reorder" })
private Grid grid;
}
