As already suggested: Is it not possible to have a setup() method called from the creationComplete event that sets the values held in the Model Locator into the text inputs? On selecting cancel the window closes and no data changes. On saving, the data is wrapped in a VO, courtesy of a view helper and written to the Model Locator (and anywhere else you wish to store these preferences). Would this not work - or is there something I have missed here?

Where do you put this code: > prefsWindow = PopUpManager.createPopUp(this, PrefsWindow, true); > prefsWindow.setFormData(ModelLocator.prefsObject); I naturally want to put this in my PrefsWindowViewHelper, but it doesn't seem to work when there. What I find is happening is every view that's a titlewindow ends up adding code to my applicationViewHelper. this "smells" i think. todd --- In [email protected], "JesterXL" <[EMAIL PROTECTED]> wrote: > > That's what I've been deadling with for the past 2 days! > > I won't suggest best practices, I'll just suggest what works as of 1:00pm > this afternoon. > > My model is much like yours, on ModelLocator, but it's not actually written > to unless the user hits save or apply.
