What wasted your time was not asking on cells-devel when you had a problem. What wasted my time was taking the trouble to do open-source. Madhu wrote:

Helu, Heres some feedback on problems I encountered when learning to use cells.

Changing a defmodel form and evaluating it often caused the system to stop functioning as expected.

An example of a change is changing an :initform FORM slot to (c-in FORM).

An example of how the system stops functioning as expected is: rules just dont fire. (echo output just does not happen). Accessors return NIL instead of computed values

lisp needs to be killed and restarted to recover. This is a showstopper. Is there a quick way to reset the cells system and recover?

(cell-reset)

Another issue is after reading the doc my expectation was set at identical behaviour from using SLOT-VALUE or an accessor. This does not happen: For example calling the accessor produces `echo output' , slot-value doesnt.

slot-value is now a back door. ie, you are right, the doc is old, slot-value no longer triggers cell-ish behavior. You might do better with McCLIM. kt
