> When calling a java script snippet defined in the form description file, viewData is
passed in the context as long as viewData is available from the objectModel and is not null.
This makes it difficult to reliably use viewData in the snippet. Consider the case where you
create a form and then dynamically assign some values to some widgets before actually showing
the form. This results in value-changed events to be fired with viewData undefined in the
context of the listener. Then using viewData in the snippet results in a reference error.
If the event is fired from a sendPageAndWait context, viewData is neatly passed.
> The problem is how to distinguish this in the event handler. It would be better to always
pass viewData be it a null value some times. Then a simple test viewData == null could be
used in the event handler. Note that viewData is also null when sendPageAndWait is called
with only one parameter.
> This problem occurs on line 69 in o.a.c.forms.event.impl.JavaScriptWidgetListener.java.
> Is this a bug or is there some intentional use?
