initialising case

Hello there.

I'm trying to start a process using scripts as right operand in Output Operation of several fields, to transform the field_XXXX data to object instance and store it in a field o a process data, and the error above is thrown.

The operator type is not the "Takes value of", but the "Use a Java method".

Any help?

I want to initiate multiple cases from the document which is being uploaded in database.

i am using Bonita 6.3.

1. Please tell me How can I upload document without Converting it to Byte(). 2.And How to initiate case from database?

Note: i am just beginner in Bonita.
