Actually, not only Parameterized Locale Messages, but any locale stored in a variable.
i.e.: In TCL: set variable_name <span>#</span>package-key.message-key#
In ADP, calling @variable_name@ will result in the actual text (<span>#</span>package-key.message-key# as it is) and not the Message of this message-key itself if it exists.
Is this the default behavior? I can't use <span>#</span>package-key.message-key# format inside variables, database variables or in the system parameters?? Or there is a way to make the system resolves this.
