excuse for my bad english.
With this reference i think to have the input set to relative
I can only guess:
value: (aDescription toString: (object readUsing: aDescription));
callback: [ :value | object write: (aDescription fromString:
value) using: aDescription ].
i work with your guess, and some thing go other no.
I'have problem with description define using MANumberDescription new ....
When, in the textInput digit an char the method visitNumberDescription: aDescription go
And if description is define with addCondition, this are not tested at callback:..
Another problem about MANumberDescription :
in description based on it, if i define beInteger or min: or max:
when digit an chart in the UI the method visitNumberDescription: aDescription go in
