Strange model set behaviour about racer HOT 8 OPEN

I can't reproduce this error. Could you give more information on data stored in model?

from racer.

Ok, the data is following:

{"game": {
  "id": "6a30efbc-741e-46ae-9c65-3b54272d58c9_new-recruit-v3",
  "scenario": {
    "11": ["hello"],
    "name": "New Recruit",
    "gameType": "new-recruit-v3",
    "gameCategory": "v3",
    "demoStrategyList": [
      "random"
    ],
    "roles": [
      "Recruiter",
      "Candidate"
    ],
    "anonymousMode": true,
    "xlsxDownload": true,

    "scenarioName": "New Recruit",
    "onlineType": "inClass",
    "rolesMeta": {
      "Recruiter": {
        "alias": "role0"
      },
      "Candidate": {
        "alias": "role1"
      }
    },
    "id": "temp_6a30efbc-741e-46ae-9c65-3b54272d58c9_new-recruit-v3",
    "_templateName": "Default",
    "base": true,
    "parentId": "a178fe18-51ae-44de-be7a-728476dbfe60"
  }
}}

I think it's important to notice that forked versions of racer and derby.js are used:
racer https://github.com/dmapper/racer#sync-upstream4
derby https://github.com/dmapper/derby#sync-upstream7

Avoid using numeric object keys with racer. While it's working on local docs (in upstream version), I believe ShareDB will reject them in remote docs.

Yes I got that using numeric object keys is a bad idea, though it looks inconsistent that it works here model.setDiffDeep('_page.game.scenario.11', ['hello123']) and writes the changes to DB without errors but doesn't work this way model.set('_page.game.scenario.11', ['hello123']). And it obviously will work in this case:

model.scope('_page.game.scenario').set
  {
      "name": "New Recruit",
      "gameType": "new-recruit-v3"
      "123":
        [
          "hello",
          "world"
        ] 
   }

from racer.

Well, the reason this model.set('_page.game.scenario.11', ['hello123']) doesn't work is that .11 makes racer interpret _page.game.scenario as array and tries to set scenario[11] to hello123. Which obviously doesn't work because _page.game.scenario is an object, hence the error. I don't know why setDiffDeep behaves differently...

from racer.

And, btw, if it is an array, it will first resize the array to at least 11 and then write to array[11]. So trying to set a property .123 will resize the array to 123. Not a good idea...

@michael-brade thanks for the information. Yes, we have an object with numeric keys, suppose it was set as follows:

model.scope('_page.game.scenario').set
  {
      'name': 'New Recruit'
      'gameType': 'new-recruit-v3'
      'courses':
         '11': ['hello']
         '127': ['world']
         'default': ['hola']
   }

then if I try to do model.set('_page.game.scenario.courses.127’, ['hello123’]) it will throw but model.setDiffDeep(‘_page.game.scenario.courses.127, ['hello123’]) will let me write into DB without any errors. I found it inconsistent.
