I just spent a couple hours trying to determine why one ComboBoxInputFieldView was broadcasting selection changes but two others were not. The exception handler in this VW 7.5 method was hiding the problem:
InputFieldView>>hasEditValue
"Answer true if the receiver contains a valid edit value, otherwise
answer false. This method should be used in conjunction with
#editValue to avoid having to handle the wide range of exceptions
that may result when conversion is requested for invalid input."
^[self editValue. true]
on: Object errorSignal
do: [:ex | ex return: false]
Cincom, please consider changing the handler to at least write something to the Transcript when an error happens. Take menus for example, when there are any problems with menus the default behavior is to write a message on the Transcript
that says what the error was and how to enable a debugger instead of just logging.
