--- Playing with defined/undefined variables
#set ( $FOO1 = "FooValue1" )
'FOO1' variable has been set, value = "$FOO1" 

#if ( $fn.isDefined("FOO1") )  ## Check by variable name (string, not object reference)
YES 'FOO1' is defined 
#else 
NO 'FOO1' is not defined 
#end
## Check with 'assert' directive (causes an error if not true)
#assertTrue($fn.isDefined("FOO1"), "F001 is not defined!")

#if ( $fn.isDefined("model") ) 
YES, the "model" object is always defined in a Telosys template
#end

--- Getting an object value with a default value if not defined
#assertFalse($fn.isDefined("FOO2"), "F002 is not supposed to be defined!")
Getting "FOO2" : $fn.get("FOO2", "my default value")
