Hi,

Did you try this in the execute method of myAuthTest class ?
execution.setVariable("myUserName2 ", "New/Updated Name");

Yes I ever tried this and this isn't working it seems like this is creating a new variable myUserName and isn't filling the proper variable that i defined in the workflow model

But when i do execution.getVariable("myUserName") and i disp it in
http://xxxxxxxxxxx:9090/activiti-app/api/runtime/process-instances/xxxxx/variables?

I'm getting this var equals to null

after doing
yousra = (Object)x ;
I get
{
    "name": "myUserName2",
    "value": "administrator",
    "scope": "local",
    "type": "string"
},

I don't understand i got the proper value but i can't use this in my RestCALL task , is it a problem about the scope ?

but you can't set a value the default value is null if you set a variable for the first time you have to use script task or serviceTask to update this variable

I'm working in r&d and we are actually testing some activiti workflow

Looking throught internet this is the only topic where we are talking about the same problems

@madn: if you define a variable like that in the service task properties, it means that your service task will set that variables in the execute() method. It is kinda like 'metadata' for your service task.

Instead of using createVariableLocal … why arent you using the setVariable() method?
