Rest JSON deserialization converted to key=value

[esseti]

Hi all.
i've a problem with the rest functions, especially the start one.
i send data in this way:

{
   "processDefinitionKey":"sid-f7f670e1-a6cf-42a7-b824-f88446256b7f",
   "variables":[
      {
         "name":"processId",
         "value":108
      },
      {
         "name":"data",
         "value":[
            {
               "lastname":"my lastname",
               "birthday":"my birthday",
               "name":"my name"
            }
         ]
      },
      {
         "name":"task_instance",
         "value":82
      }
   ]
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

now, inside one of my task i load the "data", but what i get is this:

[{lastname=my lastname, birthday=my birthday, name=my name}] 
‍‍‍

that's wrong.

how can i solve this problem?

What a coincidence, I have a blog-post about this ready and will be posted today. I'll post the link here once it's online!

i found that it is already parsed. so i've to encode it twice to do the parsing manually.

[frederikherema1]

Yes, it's parsed into a Map by Jackson…

mmm.
another thing.
i'm trying to write a script to manipluate a json object with groovy and script task.
this is the object (it's "data", an execution variable):

[{"validation": "7"}, {"validation": "5"}]
when i try to check the lenght, it gives me this:

size 42
basically it's understood as a string and not as a json list.

any idea?

[frederikherema1]

How is the variable stored in the process (which type)? Check the ACT_RU_VARIABLE or use the API to fetch the variable value yourself (not in a script)…

[esseti]

The fact is that by sending a singal i can only send a string (or other first-class types).
Probably also for the start process i can't send json objects (i actually send a string). but there i've a java class that does the translation, and it stores a JSONObject with setVariable.
The problem is with signals. I can't make it receiving a json object. I tried and i seen them as "null" in a script task.
Right now I made a compiler that takes the process and adds a service task after each receive.
i've to test it. wondering if there's a better solution. but if it works than fine (i've to compile the process anyway).
