Hi everybody,

I have the following HTML

<div id="tagsList" class="tags-cloud col-xs-12">
                    <div ng-repeat="filter in filters.filters">
                        <div class="tag">
                            <span><span>{{filter.columnDisplayName + " "}}</span>
                            <span class="operator">{{filter.strOperator}}</span>
                            <span>{{' "' + filter.displayValue + '"'}}</span></span>
                            <span><b ng-click="removeFilter($index)" class="cross">x</b></span>
                        </div>
                        <span class="logic" ng-show="!$last">{{filters.logic}}</span>
                    </div>
                </div>

I want to change the {{filter.strOperator}} into

{{getOperatorDescription(filter.strOperator)}}

However, I am getting errors when I try that.

First time it works, then the second time I get

TypeError: Cannot create property 'value' on string ''

I am not sure how should I make it to work.

Thanks in advance.
