Unable to capture Action_Success event during update

Question

Hi I am using SAP-B1 2004. Using UIAPI, i am trying to do something when an item information in item master is updated.
On update button click i am capturing the Before_Action =True event to do something. If the Item information is successfully updated, i am trying to capture Action_Success = True event to do something.
The problem i am encountering is that, the Action_Success event is not getting fired.
After Before_Action =True , Before_Action =false event is getting fired and after that the item uid value changes from 1 (for update button) to some other value.
Any idea why this is happening? My code is as follows:
If pVal.FormType = 150 And pVal.FormMode = 2 Then
   If pVal.ItemUID = "1" And pVal.EventType =   
       et_ITEM_PRESSED And pVal.Before_Action = True Then
       **Do Something***
   End If
   If pVal.ItemUID = "1" And pVal.EventType = 
       et_ITEM_PRESSED And pVal.Action_Success = True Then
       **Do Something***
   End If
   If pVal.ItemUID = "1" And pVal.EventType = 
      et_ITEM_PRESSED And pVal.Action_Success = false Then
       **Do Something***           
   End If
End If
Thanks.

Just change the second condition from
If pVal.ItemUID = "1" And pVal.EventType =
et_ITEM_PRESSED And pVal.Action_Success = True Then
to
If pVal.ItemUID = "1" And pVal.EventType =
et_ITEM_PRESSED And pVal.BeforeAction = false Then
and forget ActionSuccess.
If there is an error in between, the "et_ITEM_PRESSED pVal.BeforeAction = false" is not sent. This means, whenever you get the event "et_ITEM_PRESSED pVal.BeforeAction = false", the action actually was successful.
You may want to test it with following proof-snippet:
If pVal.FormType = 150 And pVal.FormMode = fm_UPDATE_MODE Then
    If pVal.ItemUID = "1" And pVal.EventType = _
        et_ITEM_PRESSED And pVal.Before_Action = True Then
        Debug.Print "before"
    End If
    If pVal.ItemUID = "1" And pVal.EventType = _
        et_ITEM_PRESSED And pVal.Before_Action = False Then
        Debug.Print "after"
    End If
    If pVal.ItemUID = "1" And pVal.EventType = _
        et_ITEM_PRESSED And pVal.Action_Success = True Then
        Debug.Print "success"
    End If
    If pVal.ItemUID = "1" And pVal.EventType = _
        et_ITEM_PRESSED And pVal.Action_Success = False Then
        Debug.Print "no success"
    End If
End If
Case 1: Update successful
Output: before, after, no success
Case 1: Update fails
Output: before, no success
Means: forget ActionSuccess, use BeforeAction true/false.
(That's how solved the problem did it when I encountered the same problem.)
Problem is, you're not able to to something if there was an error. But why would you want to? User sees a red error message and tryes again...
