[Seaside] call: works intermittently on Pharo

[Larry White]

Sebastian, Thanks.

I am sending from within a callback. I got this case to work by eliminating
a component that acted like a container between the root component and the
component where the non-working render methods were implemented.  Now I just
have to understand -why- that would work and the other way not.
