 Description   

When a subscription resource is created under a container resource, the state tag in the container resource does not increment. Note that creating contentInstance does increment the stateTag

Example below shows a container resource with 3 contentInstances and 2 subscriptions. Its state tag is =3, should be =5

According to TS-0001,John and I decide that:

Only when create <ContentInstance> should increment st.
create <container> <subscription> will not.

Hello Cangji Wu,

Following behaviour is being oberserved while replicating the bug :
1 : Value for state tag is not increasing upon creation of subscription under container .

2 :
Sceneario : CSE - AE- container -

{ * create 3 contentInstance }
{ * create 2 Subscription }
{ * create 1 contentInstance }

Upon creation of 3 contentInstance the state tag value is increased to 3 (Correct).
But if we create subscription in between and then create contentInstances again, the state tag value increases by 2 for each contentInstance.

3:
Sceneario : CSE - AE- container - {* create Subscription }

{* create contentInstance }

In above Scenario the state tag value is increasing normally by 1 for each contentInstance.

So for 2nd scenario there is a need to fix the bug.

Please confirm If it is to be solved,I will be looking into the code.
