Ok :) These methods only exists in Pharo 3.0 :) Ben On 06 Nov 2013, at 08:38, Bahman Movaqar <Bahman@BahmanM.com> wrote:

This is the expected behaviour :)
Oh! A bit unorthodox, specially considering the shortcut (CTRL+S) --I was expecting something like ENTER :-)
There is also acceptOnCr :)
That clearly shows I have to work on my "exploration" skills :-)
But what you can do (and actually what you wanna do) is to accept the text at each keyStroke :)
initializePresenter self instantiateModels: #( textName TextModel labelGreeting LabelModel buttonGreet ButtonModel ). labelGreeting text: ''. buttonGreet label: 'Greet Me!'; disable.
should be turned into:
#initializePresenter textName := self newTextInput. labelGreeting := self newLabel. buttonGreet := self newButton.
Would you please explain the RHS of the statements? I don't understand `self newTextInput`.
Itâs equivalent to self instantiateModels: #(textName TextInputFieldModel). It simply creates a new sub model for you :)
Hmm...Pharo rejects those lines, e.g. with "Unknown select newTextInput". I guess I'm sub-classing the wrong class. Here's my class definition:
<code> ComposableModel subclass: #FirstSpec instanceVariableNames: 'textName labelGreeting buttonGreet' classVariableNames: '' poolDictionaries: '' category: 'Bahman-Spec' </code>
labelGreeting text: ''. buttonGreet label: 'Greet Me!'; disable. textName autoAccept: true.
It's certainly no big deal but I'm just curious; any special reason why `autoAccept` doesn't default to true?
Thatâs actually a good question :) I guess the answer is historical :)
Ancestral remains, huh? :-)

Hi all,
I'm writing a simple graphical version of the legendary "Hello, world". I have a window with a text field, a button and a label. What I'm trying to do is to make the button (which is initially disabled) enabled upon user entering text. However, it seems that the user first must "Accept" the text for the action to be fired.
Here's some snippets of code:
<code> initializePresenter textName whenTextChanged: [ buttonGreet enable ]. buttonGreet action: [ labelGreeting text: 'Hello, ', textName text, '!'. buttonGreet disable ].
initializeWidgets self instantiateModels: #( textName TextModel labelGreeting LabelModel buttonGreet ButtonModel ).
labelGreeting text: ''. buttonGreet label: 'Greet Me!'; disable. </code>
What am I doing wrong?
TIA,
PS: I have tried `whenTextChanged` to no avail --it shows the same behaviour.
