Problem with multi instance workflow

Hi, I am new to activiti. It might be a silly question.Please find below my process definition <blockcode> <process id="TestMultiInstance" name="TestMultiInstance" isExecutable="true"> <startEvent id="startEvent1"/> <sequenceFlow id="sid-6186FC5D-9FC7-4A36-948B-36C914A69A

Hi,

Can you check in the database if the contacts variable is created in the ACT_RU_VARIABLE table?
If you can share a unit test project showing the error, so we can easily reproduce it that would be helpful.
I don't see any immediate issues with your code.

Best regards,

Hi Tijs,

Thank you for the replay.
I have checked data base, there is a entry created in ACT_RU_VARIABLE table with name contacts.

In my case, Multi Instance will create 2 instances (As Collection is of size 2)

I have enabled debug logs of activiti,
please find below lines of logs from activiti, It might help you to understand my problem.
