Question

Latest version(s) of Breeze appear to break executeQueryLocally. For example:

var query = new breeze.EntityQuery()
            .from("Items").where('id', '==', id);

return manager.executeQueryLocally(query);

The issue I am encountering is in the stringEquals call in getPredicateFn.

In the case of the simple query above, trim()is being called on id causing a

5 has no method ‘trim’

Exception.

Here is the Breeze stringEquals function:

 function stringEquals(a, b, lqco) {
    if (lqco.usesSql92CompliantStringComparison) {
        a = (a || "").trim();
        b = (b || "").trim();
    }
    if (!lqco.isCaseSensitive) {
        a = (a || "").toLowerCase();
        b = (b || "").toLowerCase();
    }
    return a == b;
}

Edit

id is defined as int on the Items model and is numeric in JavaScript. Earlier version of Breeze did not do stringEquals so there was no attempt to trim a numeric.

Ok, this should be fixed. Please check v0.73.1. Breeze predicates will now perform type coercion when comparing values of different types (like strings vs numerics).
