I have a component embedded within another component (it is included in
the wod-descriton file)
which gets displayed as a webpage.
The embedded one represents a Form with a set of WOTextFields. When the
submit-button is
activated, the outer component needs to know if something in the
textfields has changed, so
that it can trigger an cost expensive event or avoid it if nothing changed.
What is the smartest way to check for that condition?
