Description
Currently, nested ifs always fail to compile with errors of the kind:
Unexpected exception: Cannot invoke "context.UniquenessAnnotation.isGreaterEqualThan(context.Uniqueness)" because "vPerm" is null
Or others related to null states.
We want to be able to support nested If statements like the following:
if (condition) {
if(condition){
/*Some code*/
}
/*Some code*/
} else {
/*Some code*/
}
