I'm having hardtime to access model attribute values in the view using thymeleaf.
<h4>Employees per Project</h4>
<table class="table table-bordered table-striped">
<thead class="thead-dark">
<tr>
<th> FirstName<span></span></th>
<th> LastName</th>
<th>Projects Count</th>
</tr>
</thead>
<tbody>
<tr th:each=" EmpPrjCnt : ${employeeProjectCount} ">
<td th:text="${EmpPrjCnt.fName}"></td>
<td th:text="${EmpPrjCnt.lname}"></td>
<td th:text="${EmpPrjCnt.Pc}"></td>
</tr>
</tbody>
</table>
</div>
Controller Code:
List<projectEmployee> employeeProjectCount= empRep.employeeProjects(); //.employeeProjects();
System.out.println("FROM Home Controller :::::::::: "+employeeProjectCount);
System.out.println("FROM Home Controller :::::::::: "+employeeProjectCount.get(1).getfName());
System.out.println("FROM Home Controller :::::::::: "+employeeProjectCount.get(1).getlName());
System.out.println("FROM Home Controller :::::::::: "+employeeProjectCount.get(1).getPc());
model.addAttribute("employeeProjectCount", employeeProjectCount);
I can access all the attributes in the controller through but not in the view. Let me know where im going wrong.
