Hello,
I would use TimeEvent as trigger for state machine transition.
- I created a TimeEvent
- Set Is relative to true
- Fill when field with a TimeExpression
-Fill time expression with a name (t) and an OpaqueExpression (10.0 for example)
But I can't generate C++ code from this example. I obtain an Exception during the transformation:
java.lang.NullPointerException

This is the relevant code :
public static long getDurationFromVSL(String nfpDuration) {
if (nfpDuration != null) {
String unit = MarteUtils.getValueFromTuple(nfpDuration, UNIT);
String value = MarteUtils.getValueFromTuple(nfpDuration, VALUE);
return Float.valueOf(value).intValue() * getMultiplicatorFromTimeUnit(unit);
}
return 0;
}
Should I use a special string format? And if yes which one? Is this feature available in C++ code generation, if yes is there somthing to set in addition?
Regards.
Yoann.
