JayLint $data.ASTParser undefined


Using Jaydata 1.3.4 with KendoUI and requireJS the $data.Expressions.CodeParser class parseExpression method often falls through to line 5678 which is:

var AST = $data.ASTParser.parseCode(code);

However, I get the error "Cannot call method 'parseCode' of undefined".

Indeed $data.ASTParser is undefined.

require-config.js looks like this:

    paths: {

        // Libs
        jquery: 'lib/kendo/js/jquery.min',
        kendo: 'lib/kendo/js/kendo.custom',

        jdata: "lib/jaydata/jaydata", 
        jdatakendo: "lib/jaydata/jaydatamodules/kendo",
        jdatasqlite: "lib/jaydata/jaydataproviders/SqLiteProvider",

        // Paths
        jdataproviders: 'lib/jaydata/jaydataproviders',
        jdatamodules: 'lib/jaydata/jaydatamodules'
    shim: {
        kendo: {
            deps: ['jquery'],
            exports: 'kendo'
        jdata: {
            deps: ['jquery'],
            exports: '$data'
        jdatakendo: {
            deps: ['jdata', 'kendo'],
            exports: 'jdatakendo'
        jdatasqlite: {
            deps: ['jdata'],
            exports: 'jdatasqlite'

The same issue was raised here previously.

are also undefined.

the quick work-around is to explicitly load jaydata.js - i.e. dont use requirejs.

However, everything is so close to working with requirejs it would be ideal to solve this niggle.

It seems that requirejs returns the parser in question when jaydata is fetched. The parser used is $data.Acorn rather than $data.ASTParser.

A workaround for the example above is be to set the parser manually, e.g.
define(['jdata'], function(jdata) {
   $data.Acorn = jdata;
