What is the best way of passing collection for multi instance sub-process when using external task approach?
Providing simple ArrayList collection raises an engine error
Cannot locate class ‘SomeObject’
which is fine cause engine shouldn’t know about serialized class. I read that you suggest using json in such cases. I try serialize my collection (over 1000 items) into String using ObjectMapper class but this exceeds maximum size of column used to store process variables
Value too long for column "TEXT_ VARCHAR(4000)
How can I proceed this?
