i can’t reproduce your problem.
Pressing the OnSave - Button : is the SuccessItem displayed in the StatusBar ? If u cant see the icon, the Adapter - Function was never called.
Tryed an Sysout within the setter - method? Check, if the Syntax of your Setters are correct.
In General the outPutMessage is not the best Method to debug in this case, because only the content of the last text field will be displayed - maybe only your last textfield is empty…
