Updating a form in Skill

Hello,

i have a question on how forms are updated in Skill when properties of elements in the form are changed in the background.

Within the following small example a form with a button gets insatiated.

button=
hiCreateButton(
                              ?name 'button
                              ?callback "printf(\"Button pushed\")"
                              ?buttonText "Push"
);hiCreateButton

form=
hiCreateAppForm(
                                ?name 'myform
                                ?fields list(button)
                                 ?formTitle "Simple Form"
);hiCreateAppForm

hiDisplayForm(form)

If i enter the code line form->button->enabled=!form->button->enabled several times in the CIW the button gets enabled/disabled. If I enter the code line button->enabled=!button->enabled nothing happens at all, although the property changes. Is there a way to update the form, if the enable property will be changed using the second way?

Many thanks.

Best regards,

Matthias
