fieldMessage
Syntax
[the] fieldMessage of <field>
set the fieldMessage of field "Postal Code" to "postCodeFieldChanged"
Explanation
The fieldMessage
property allows you to specify the name of a command message to be
sent to this field (and then up the message hierarchy to the card, window and project)
when the field’s has been changed. This is sent in addition to the closeField
message, and is
especially useful when you want to handle clicks in certain fields at a higher level
(e.g. funnel changes to a form through the card to be handled centrally).
