[Seaside] Task Escape

[Keith Hodges]

or... you could try a message eating null. I know that people are alway
suspicious of letting message eating null loose in their code, however I
do think that in a specific controlled situation it can be very useful.

You example becomes...

self stepOne stepTwo stepThree.

if any of the steps returns Null then the subsequent steps are passed over.

Null is available in universes.

cheers
