Hi All,

Recently I changed the datatype of a variable in a custom class from Integer to Double.
When I start processing the older applications activiti is throwing classcastexception while assigning Integer to Double.

Could anybody can help me how to get rid of this problem in activiti based applications?

Can I modify the BLOB serializied object in ACT_GE_BYTEARRAY table in any way to set the changed datatype?
Or any other ways there to handle the deserializing process of activiti?

If anyone can help with bit details it would be much helpful.
