Problem with titleMap and select

[chachou29]

Hello,

form :
 [
    {
      "key": "choice",
      "type": "select",
      "titleMap": {
        "one": "One",
        "two": "More..."
      }
    }
  ]

schema :

{
    "type": "object",
    "properties": {
      "choice": {
        "type": "string"
      }
    }
}

is not working. Dropdown is empty.
but if you change "select" type to "radios" or "radiobuttons", it works fine !
I think the problem is with titleMap, if you use an "enum" in the schema then "select" works fine.

Thank you !
Philippe

Hi!

Ah yes, we did a fix a while ago that changed it from looping over the titleMap in the form to looping over the schemas enum, this was to get the correct order from the enum. I didn't realize at the time that it broke the titleMap feature if you didn't have a enum. Which of course is wrong... Marking it as a bug.

I also think the title map should rather be a list of dicts.

Then we can use it also for boolean fields (sometimes it's nice to render them as radio buttons and not as a checkbox).

My solution atm is:

"form" :
 [
    {
      "key": "choice",
      "type": "radios",
      "titleMap": [
        {"value": true, "name: "Yes, I want to get the big beer."},
        {"value": false, "name": "No, that's too much for me."}
      ]
    }
  ]

This requires just a minor change in the template then.

@torstenrudolf's solution also has the advantage of correctly specifying the order of the radio elements, as key order is not guaranteed in JS and tends to be alphabetized by JSON beautifies, etc. +1 from me

[davidlgj]

@mike-marcacci Yes exactly! But I do want to support the old version of titleMap as well since that is compatible with JSON Form, should be simple enough though. Putting it on the slightly large todo list :-)

[davidlgj]

The new format is in the development branch now, internally it always uses lists for titleMap:s but the form definition can still use the "old" way with an object (to keep JSON Form compatability). Please check it out if you have time, it hasn't got nearly as much testing done as it should have.

It should also this issues original problem.
