RestDataSource with nested DataSource field produces endless loop

[ect]

The issue is present at least in stock smartgwt-3.1 and the latest nightly build of that version.
It is caused by DataSource.js in the method validateJSONRecord:

There are two nested for loops using the same index:

validateJSONRecord : function (record) {
        var fieldNames = this.getFieldNames(),
            result = {};
        for (var i = 0; i < fieldNames.length; i++) {
            (...)
                if (fieldDS && !(fieldDS.skipJSONValidation)) {
                    if (!(isc.isAn.Array(fieldValue))) {
                        fieldValue = fieldDS.validateJSONRecord(fieldValue);    
                    } else {
                        for (var i = 0; i < fieldValue.length; i++) {
                            fieldValue[i] = fieldDS.validateJSONRecord(fieldValue[i]);
                        }
                    }                    
                }
             (...)

Changing the inner loop index from i to j solves the issue.

Thanks for the report - this has been addressed in 8.3p/3.1p and 9.0d/4.0d - please retry with a nightly build of January 11 or later
