Wrong key for Array item if specific item is selected

[Fankhauser-Dominik]

Describe the bug

When I select a single item from an array through the uischema, I get a wrong key. I think it is because of the items object. If I do the same with a normal object (without items) instead of an array, then I get the expected result.

schema

{
 "definitions": {
   "order": {
     "type": "object",
     "properties": {
       "title": {
         "type": "string",
         "minLength": 5
       },
       "ordered": {
         "type": "boolean"
       },
       "assignee": {
         "type": "string"
       },
       "choices": {
         "type": "array",
         "items": {
           "type": "string"
         }
       }
     },
     "required": ["title"]
   }
 },
 "type": "object",
 "properties": {
   "orders": {
     "type": "array",
     "items": {
       "$ref": "#/definitions/order",
       "format": "html",
       "title": "Multi Text Area"
     }
   }
 }
}

uischema

{
 "type": "VerticalLayout",
 "elements": [
   {
     "type": "Control",
     "scope": "#/properties/orders/items/properties/title"
   }
 ]
}

If got the following data:

{
  "orders": {
    "properties": "Test"
  }
}

Expected behavior

I expect this output:

{
  "orders": {
    "title": "Test"
  }
}

Hi @Fankhauser-Dominik, we don't really support rendering controls of (nested) array elements outside of an array control which is why I'm not surprised that it fails at the data path calculation.

What exactly is the use case? Would you like to refer to the first element of the array then? Why not use a regular array control?
