delete Object

[victor Saquicela]

I have the last CVS of delete cache.

Whe i try delete a object, produced a error in :
Private Sub deletePrivateObject
..
..
If m_useCache Then
            m_cache.Remove(obj) 'remove from the cache
End If

I comment this code and this is correct.

Hi Victor,

I've done testing on the delete locally and can't get it to fail.  Can you let me know what the error message is that you are getting.

The delete call shouldn't be commented otherwise the cache may return the deleted object during retrieve operations.

Hi.
I understant that, what if  i comment, the object is in the cache, but if i don't comment, it is produce a mistake:

Excepcin no controlada del tipo 'AToMSFramework.DeleteException' en microsoft.visualbasic.dll

Informacin adicional: Referencia a objeto no establecida como instancia de un objeto.

In this code is produced a mistake(  Class:CCacheEntry /////  Public Overloads Sub Remove(ByVal obj As CPersistentObject)
):

If obj.getClassMap.RelationalDatabase.getConnection(Nothing).Started Then
            ce = MyBase.Item(ckey)
            ce.TransactionType = CCacheEntry.CacheTransaction.Deleted

What happen if the object isn't in the cache ???

[Richard Banks]

Argh!  You're right and I'm blind :-)

Simple change:

If obj.getClassMap.RelationalDatabase.getConnection(Nothing).Started Then
  ce = MyBase.Item(ckey)
  If Not (ce Is Nothing) Then
    ce.TransactionType = CCacheEntry.CacheTransaction.Deleted
  End If
Else
  MyBase.Remove(ckey)
End If

I'll update CVS.

Thanks,
Richard.

All right.

Excellent work. I am going to continue trying your code.
