Refere parent record from MetaJsonModel

I would like to reference parent form attributes from a MetaJsonModel

can you please explain the problem .

I created a JsonMetaField (myJMF) of type Custom-OneToMany , whose target JsonModel references my MetaJsonModel (myMJM)
for the com.axelor.apps.stock.db.StockMove model.

From the stock-move-form view I would like to retrieve the stockMoveSeq from my StockMove object and display them in the grid of myMJM.
