Breezejs Double trouble in angularjs

Question

I am trying to change a value in a angular view from a integer to a float/double value that is bind to ngmodel. The input don’t except anything other than a integer.

Answer 1

I tracked down the behaviour in the breeze code, when the value change it is intercepted and parsed:

var coerceToFloat = function (source, sourceTypeName) {
   if (sourceTypeName === "string") {
        var src = source.trim();
        if (src === "") return null;
         var val = parseFloat(src);
        return isNaN(val) ? source : val;
    }
    return source;
};

So when the value change this function is called that parse the string to a float, the problem is as soon as the value entered is some number and a point like 5. it parse it to the number 5 witch is obviously correct. So you will never be able to get past the point.

When changing the input to a number type it works because its sourceTypeName is not a string.

Update

I ended up changing the breeze code to enable the decimal to be entered, I’m still not sure if I missed something but this works for me.

var coerceToFloat = function (source, sourceTypeName) {
    if (sourceTypeName === "string") {
        var src = source.trim();
        if (src === "") return null;
        var val;
        if (src.indexOf('.', src.length - 1) !== -1) {
            val = src;
        }
        else {
            val = parseFloat(src);
        }
        return isNaN(val) ? source : val;
    }
    return source;
};
