AngularJs : one of four params,passed to directive is undefined - angularjs

Question

I have a modal view(.jsp) that has integrated directive (named as 'querybuilder', Yellow part in the picture - a js file). Controller(named as 'addEditRuleSetCtrl') and directive is included from upper level and inclusion seems fine. We have initiated the directive from the view as :
<div ng-init="addEditRuleSetCtrl.initSelectors()">
<query-builder group="addEditRuleSetCtrl.filter.group"
rule-condition-operators="addEditRuleSetCtrl.ruleConditionOperators"
rule-condition-set-operators="addEditRuleSetCtrl.ruleConditionSetOperators"
fields="addEditRuleSetCtrl.fieldCodes"
></query-builder>
</div>
Where "addEditRuleSetCtrl.initSelectors()" initiates all the params passed to the directive as :
self.initSelectors = function()
{
self.getRuleConditionOperators();
self.getRuleConditionSetOperators();
self.fieldCodes = self.getCorrespondingFields();
console.log("initSelectors : fieldCodes: " + JSON.stringify(self.fieldCodes ));
}
self.getCorrespondingFields = function()
{
return self.origin == 'DDE' ? self.fieldsDDE : self.fieldsATT;
};
And the params were declared in the controller in this way:
self.fieldsDDE = [
{ name: 'FirstnameDDE' },
{ name: 'LastnameDDE' },
{ name: 'BirthdateDDE' },
{ name: 'CityDDE' },
{ name: 'CountryDDE' }
];
self.fieldsATT = [
{ name: 'FirstnameATT' },
{ name: 'LastnameATT' },
{ name: 'BirthdateATT' },
{ name: 'CityATT' },
{ name: 'CountryATT' }
];
self.fieldCodes = [];
self.ruleConditionSetOperators = [];
self.ruleConditionOperators = [];
The problem is: one ( the param 'fieldCodes')of the four params that passed to the directive is "undefined" Although they were defined ,passed in similar way. I have cleaned the cache and tested all possible ways but nothing made any difference.As a result the associated dropdown is empty (in the red-arrowed dropdown in the screenshot).Any clue?

Answer 1

At my first glance of the directive, I think you probably should change from:
var test = scope.$parent.fieldCodes;
scope.fields = scope.$parent.fields;
To:
//var test = scope.$parent.fieldCodes;
scope.fields = scope.$parent.fieldCodes;
