#33 CHOICE with SEQUENCE elements

[Bechir Allani]

I try to implement a CHOICE with SEQUENCE elements from which a single element can be selected.
The Problem when I set the first sequence, it's works fine, but when I set for example the second one, my program throws the following exception:

java.lang.IllegalArgumentException: The mandatory field 'farbe' does not have a value!

As you can see the function decodeSequenceField throws an exception and it's right, but not in case when it called from a decodeChoice function, because in this example just one SEQUENCE element from the choice could be selected and the rest of SEQUENCE elements are Null
