This is the expected behaviour :)

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.

labelGreeting text: ''.

buttonGreet label: 'Greet Me!'; disable.

textName autoAccept: true.

Keep me in touch :)

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.
