[Pharo-users] Spec - TextModel whenTextIsAccepted

[Bahman Movaqar]

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.
