Collection Form Case Variable

Show process variable of type java.util.Collection in Form

Hi All,

I'm trying to access process variable which is a list of objects from the form. In form I used External URL call to retrieve it:

../API/bpm/caseVariable/{{caseId}}/mySpec

And it returns the following:

{ "case_id": "1040", "name": "mySpec", "description": "", "type": "java.util.Collection", "value": "[com.company.model.Specification@221f0410, com.company.model.Specification@90ff9aa4, com.company.model.Specification@54bde939]" }

As far as I understand it returns some kind of references, but how do I get actual data?

BR,
Roman
