Calculation in custom forms only works in preview

[Laura]

Hey,

I created some custom forms in which some calculation is done. My problem is, that this only works in the preview. When I save my settings and run the form, the field, where the result of the calculation should be displayed remains empty.

For example I wanna add two values of two number fields. The result should be displayed in a further field. All three field are in one panel. (Details below)

Do you habe an idea to solve this issue?

XNAT version: 1.8.8

And the .json code of the panel:

{
  "title": "Addition",
  "theme": "warning",
  "collapsible": false,
  "key": "addition",
  "type": "panel",
  "label": "Panel",
  "input": false,
  "tableView": false,
  "components": [
    {
      "key": "number1",
      "type": "xnatNumber",
      "input": true,
      "label": "Number 1",
      "delimiter": false,
      "tableView": false,
      "requireDecimal": false,
      "truncateMultipleSpaces": false
    },
    {
      "key": "number2",
      "type": "xnatNumber",
      "input": true,
      "label": "Number 2",
      "delimiter": false,
      "tableView": false,
      "requireDecimal": false,
      "truncateMultipleSpaces": false
    },
    {
      "label": "Result (Textfield)",
      "redrawOn": "data",
      "calculateValue": {
        "+": [
          {
            "var": "data.number1"
          },
          {
            "var": "data.number2"
          }
        ]
      },
      "key": "result",
      "type": "textfield",
      "input": true,
      "prefix": "=",
      "disabled": true,
      "refreshOn": "change",
      "tableView": true,
      "keyModified": true
    }
  ]
}

Hi Laura,

Unfortunately, calculated value type fields are not currently supported within the current version of XNAT custom forms. As such, this is the expected functionality for these inputs. We are planning to add this type of field into XNAT in a future version of custom forms and we have noted down your interest in them within our ticketing system.

Thanks for reaching out,

Ian

Hi Ian, 

I would like to ask you if there is any current development in this matter. Laura used to work in our group and helped us setting up xnat and custom forms.
