Can not put validation rules on integer attributes

[fracz]

I'm submitting a feature request or bug report, really don't know

• Library Version:
  1.1.2

I want to validate the following object:

let myObject  = {
  2: '',
  5: ''
};

The identifiers of properties are dynamic based on my data model.

The 1st try

ValidationRules.ensure(2).required().on(myObject);

results in the following error

aurelia-task-queue.js:59 Uncaught Error: Unable to parse accessor function: 2

The 2nd try

ValidationRules.ensure(obj => obj[2]).required().on(myObject);

Uncaught Error: Unable to parse accessor function: function (obj) { return obj[2]; }

OT: In fact, I have noticed that .ensure(obj => obj.someProp) works but .ensure(obj => obj['someProp']) does not. See this gist for reference.

The 3rd try

ValidationRules.ensure('2').required().on(myObject);

builds the validation rules indeed, but they are not applied when used with validate binding behavior. I have debugged it down to this line which compares '2' !== 2 and skips the validation.

The 4rd try (ugly hack aka workaround)
This works, but is far from pretty.

const v = ValidationRules.ensure('2').required();
v.rules.forEach(rules => rules.forEach(rule => rule.property.name = parseInt(rule.property.name)));
v.on(myObject);

If you change:

validation/src/implementation/standard-validator.ts

Line 104 in 40060d7

if (!validateAllProperties && rule.property.name !== propertyName) {

To:

if (!validateAllProperties && rule.property.name !== propertyName.toString()) { 

does it work?

Adding the toString() there causes the validation to be applied on given field as expected. However, the error is not being rendered in the GUI (I am using "standard" BootstrapValidationRenderer from examples). It works, when using my hack so I guess there is another strict comparison somewhere.
