[Seaside] How to control ID of a component?

What about creating an unique ID for each component and store that in
an instance variable?

    '_' , SmallInteger maxVal atRandom asString

makes quite a nice ID. Also WAExternalID from Seaside generates nice
IDs that are very unlikely to collide.

If you don't want to waste any space, you could also use the
#identityHash of the object. In Squeak this is not particularly safe
to do, but in GemStone the OOP gives an ideal and free DOM ID for your
objects.

Cheers,
Lukas
