I don't believe it is currently supported in the rest api like that. A serialized arraylist might work.

But nointheless, it makes sense to have it. Could you create a jira issue to follow up?

I can't find the way of starting a process with REST which has got a variable (called list_of_assignees) type string.
I use the variable in a loop this way:
<multiInstanceLoopCharacteristics isSequential="false" activiti:collection="${list_of_assignees}" activiti:elementVariable="assignee"></multiInstanceLoopCharacteristics>

When I try to start the process setting a list of user names (comma separated), the errorMessage shows that the variable 'didn't resolve to a Collection'.
Could anybody give me a hand?
Thanks in advance

Well, the error message basically says it all. The variable needs to be a Collection and not a comma separated string.

Best regards,

Of course, but there is no kind of "collection" data type, right?
So, should I include some scriptTask to turn the string into a collection?
Any help will be welcome!

> to turn the string into a collection

That's an option.

I don't know from the top of my head which data types the rest api accepts. But a collection of primitive data types should be there, if not it would be most useful to add it.

Thanks for your answer.
I managed to start the process posting the variable (string) as a collection this way:
"value":["USER1","USER2"]
, it was just a JSON question 🙂
