How to override Approval Action in Sales Order

Hello ​@vannakheng 

Can you try below code

 [PXOverride]
 public PXAction<SOOrder> approve;
 [PXButton(CommitChanges = true),
  PXUIField(DisplayName = "Approve", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)]
 public virtual IEnumerable Approve(PXAdapter adapter)
 {
     return adapter.Get();
 }

Can you show me some example

 [PXOverride]
 public PXAction<SOOrder> approve;
 [PXButton(CommitChanges = true),
  PXUIField(DisplayName = "Approve", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select)]
 public virtual IEnumerable Approve(PXAdapter adapter)
 {
     return adapter.Get();
 }

Method Void Approve(PX.Objects.SO.SOOrder, ApproveDelegate) in graph extension is marked as [PXOverride], but the original method with such name has not been found in PXGraph

​@vannakheng If you click on my name and go to the posts and replies you will find a lots of topics/conversation in regarding the approval. I have worked intensely on Approval. The thing is Approval methods are executed twice if you try to override (you will see them in my posts), one through the class and second time through the Approval view. You can override the class but Approval view will give you a hard time in whatever you are trying to do as it attaches a tons of handlers to graph. Depending on what you want to do you definitely need VS to code and trace and you might spend days or weeks and spin around yourself. 

see these recent ones for example. I know you might think you want to do something different but it is guaranteed you will fall into the loopholes if you try to override anything in the Approval Workflow.
