[Cuis-dev] Rerendering when touched

[Hilaire Fernandes]

Hi Paul,

Thinking again about the topic

I think the UI-Mold package (A helper tool to describe dialog panel for 
user input and validation) presents a situation where it could be a big 
advantage for simplicity to rebuild the whole UI.

Indeed the field checking required hacking in the existing morph tree 
(see validateInput) and rebuilding the whole UI depending on the 
validity of the data could simplify code a a little.

You may want to see how you can adapt Mold to the paradigm you are 
working one.

Incidentally, the Mold package came from Seaside folks[2]. I adapted it 
for field input and validation in Cuis Morph GUI. I am planning to use 
it in my forthcoming revisite of the Dynabook concept, in its 
administrative part of school related data.
