Whoops, I see my confusion, thanks for clearing that up.
I just tried to add
id="grid1"
to the <t:grid tag, like
<t:grid
....
t:id="grid1"
id="grid1"
....
but I get
org.apache.tapestry5.ioc.util.UnknownValueException: Class [my page class] does
not contain a property (or public field) named 'grid1'.
However I also realized that a solution where I need to modify all the
templates of pages that contain grids won't do. I need the Grid component
itself to generate a client-side id in the client HTML and provide a way for my
page classes to know this id. I hope there is a way to do so and then I will
see if I can extend / compose / customize the Grid component to do that.
