Angularjs過濾器錯誤

Question

我有一個過濾器，所以你可以過濾一個角色。它看起來像這樣：

<h3>Role</h3> 
<form> 
    <div class="radio radio-primary"> 
     <label> 
      <input checked="checked" ng-click="homeCtrl.roleFilter = ''" name="role" type="radio"/><span class="circle"></span><span class="check"></span>Alles 
     </label> 
    </div> 

    <div class="radio radio-primary" ng-repeat="employee in homeCtrl.employees | unique:'Role.RoleName'"> 
     <label> 
      <input ng-click="homeCtrl.roleFilter = employee.Role.RoleName" name="role" type="radio"/><span class="circle"></span><span class="check"></span>{{ employee.Role.RoleName }} 
     </label> 
    </div> 
</form> 

<table class="table table-hover"> 
    <thead> 
    <tr> 
     <th>Functie</th> 
     <th>Bedrijf</th> 
     <th>Naam</th> 
     <th>Achternaam</th> 
    </tr> 
    </thead> 
    <tbody> 
    <tr ng-repeat="employee in homeCtrl.employees | filter: { Role.RoleName: homeCtrl.roleFilter }" ng-click="homeCtrl.redirectToShow(employee.EmployeeId,$event)"> 
     <td>{{ employee.Role.RoleName }}</td> 
     <td>{{ employee.Department.Company.CompanyName }}</td> 
     <td>{{ employee.FirstName }}</td> 
     <td>{{ employee.LastName }}</td> 
     <td ng-if="homeCtrl.canEditAdmin || homeCtrl.canEditInternAdmin && employee.Role.RoleName == 'Stagiaire'" ng-click="homeCtrl.redirectToEdit(employee.EmployeeId,$event)"><span class="glyphicon glyphicon-pencil"></span></td> 
    </tr> 
    </tbody> 
</table> 

但它不工作。當我在我的控制器中輸入console.log時，一切都會收到。什麼可能是錯的？

錯誤消息：

Error: $parse:syntax 
Syntax Error 
Syntax Error: Token '.' is unexpected, expecting [:] at column 36 of the expression [homeCtrl.employees |] starting at [{4}]. 

當我把RoleName直接僱員對象是這樣的：employee.RoleName（而不是employee.Role.RoleName）它的工作？

解決方案，張貼在我的評論：

filter: { Role:{RoleName: homeCtrl.roleFilter }}
