Thanx Alexandre,

Yes I know.

I was thiking something along the lines of
objArrayLayer[0].events.on({ "visibilitychanged": Toggle });

but that does not relate to a mapfishlayertree object at all.  Do you
have examples of triggering a "visibilitychanged" event so that the
corresponding layertree tickbox is ticked after the layer's visibility
is set to true ?

Cheers,

Yves
