Fail to group several segments in a hierarchy of member classes when de-serialize

[maussi]

Hi. Do I miss proper usage of EdiSegmentGroup attribute?

Here is excerpt of 943 Warehouse Stock Transfer Shipment Advice, where W04 is “Item detail total” and N9 is a reference to this detail. My intention is to encapsulate in a member class of Line the identification (N9) and item details (W04) in of Purchase Order.

Problem is that the ItemDetailTotal type in my code is de-serialized as a null and segment W04 elements are not assigned to properties of ItemDetailTotal.
I only can get it working when put all segments for W04 and N9 directly under Line member class, that is the closest I can get. I thought of keeping them in individual member classes with EdiSegment attributes as below.

ST*943*000001234~ W06*R*15107*20210329********PO~ N1*WH**12*1111~ N3*Abcd~ W27*M*KTML~ W04*1000*EA**VN*5900*LT~ N9*LI*10~ W04*5000*EA**VN*8530*LT~ N9*LI*20~ W03*0~ SE*12*000007242~
