Disable element in case does not work for atomic element

[idbr]

In a case-control, disabling a composite in a case works, but if the case is a single element, it doesn't (in r1792).

For example, change the case-control sample as follows:

"cases": {
    "t" : {
        "base": "string",
        "label": "Text",
        "+validators": { "required": {} },
        "control": {
            "base": "input-control",
            "initial": {
              "value": "Enter text",
              "enable": false
            }
        }
    },
    "n" : {
        "base": "composite",
        "label": "Number",
        "control": {
            "initial": {
              "enable": false
            }
        },
        "members": {
            "test": "string",
            "test2": "integer"
        }
    }
}

You'll notice that for case Text, the input field is enabled, and for the Number case, both input fields are disabled.

More info:

• When you add an initial value to the composite element, it isn't disabled either. (eg. value: {test:"hello", test2:10})
• However, when you remove the initial value from the single element case the problem persists (i.e. it doesn't become disabled like the no-value composite)

(In [1799]) Resetting a case control should also reset its valueControls.

see #400.
This fixes the problem adressed in the main ticket's description, but another problem persists:
If you add an initial value to the AbstractContainerControl?, reset() is called on the composite case control,
causing it to be visible at startup.

Ressigning to mpo for remaining problem. Please review this suggested fix:

http://dev.outerthought.org/trac/outerthought_kauri/browser/trunk/modules/kauri-forms/kauri-forms-framework/src/main/kauri/static-%7Bbuild%7D.key/kauri.forms/control.js#L2286

Remove the if/else and leave these two lines (in this order):

Control.reset(me);
me.eachChild(AbstractContainerControl.childReset);

r1799 causes #430 , which makes the case control practically unusable.
I suggest reverting this commit until a more complete fix is available.

In [1807]:

Properly reset & show/hide case control children.
