Const.PM_BlobRollback
The Const.PM_BlobRollback message is sent to all data items that have the Const.CHILDTYPE_Blob type set when BLOB client rollback needs to be performed.
| Name | Description |

Application should return TRUE if the rollback was successfully performed, FALSE otherwise.
This message is used by the framework class cPictureDataItem. Applications that do not use any other form of BLOBs do not need to implement this message.
