Calling startactivityforresult inside activity that has been called by startactivityforresult

Question

I have this issue that I have a list of A and I can add new A , so I startactivityforresult activity with form for A and there is also a button for selecting AType , so I startactivityforresult another activity with AType list.
Problem comes when I do post back result in AType list.

Intent intent = new Intent();
intent.putExtra("aType", aType);
setResult(RESULT_OK, intent);
finish();

And the result is pushed back to A List instead of A Form.
Is this normal behavior or I am doing something wrong?
If this is normal behavior, what can I do to push back result to A Form instead of A List.

If you need more code - I will provide, but I find it now irrelevant.

---

I have found out that A Form finishes after startactivityforresult call. But why?

Answer 1

Activity1:

Intent intent-=new Intent(this,myclass.class);
startActivityforResult(intent,100);

Override the method OnACtivity result in Activity 1

Activity2:

setResult(RESULT_OK);
finish();

Answer 2

原来我在AndroidManifest.xml具有活动A Form noHistory="true" ，这就是为什么它返回到A List Activity的原因
