Method Names
A method name has to be a text string without spaces. The string can contain letters, numbers, and underscores. Java® programming language keywords cannot be used. The name must not begin by a number (this is also true for the name of a form object, variable, and method).
A global method cannot have the same name as a form method and vice versa. In addition, the following names are reserved since they are used as names of local methods:
onActivate
onClick
onClose
onDataChange
onEvent
onFocusGained
onFocusLost
onLoad
onPickingChanged
onStartup
onShutdown
