Hi,
i have backpack crud controller.. im using one controller to divide the user list depending on their status..
here is my controller:

<?php namespace App\Http\Controllers\Admin;

use Backpack\CRUD\app\Http\Controllers\CrudController;
use validator;
use Illuminate\Http\Request;
use Spatie\Permission\Traits\HasRoles;
use App\User;
// VALIDATION: change the requests to match your own file names if you need form validation
use App\Http\Requests\StudentListsRequest as StoreRequest;
use App\Http\Requests\StudentListsRequest as UpdateRequest;

class StudentListsCrudController extends CrudController {
use HasRoles;
    public function __construct() {
        parent::__construct();

        $this->crud->setModel("App\Models\StudentLists");
        $this->crud->setRoute("admin/student-list");
        $this->crud->setEntityNameStrings('New Student', 'Student List');
        // $this->crud->enableAjaxTable();
        $this->crud->enableExportButtons();

        $this->crud->setFromDb();
        $this->crud->addField([
                            'name' => 'password_confirmation',
                            'label' => 'Password Confirmation',
                            'type' => 'password',
                            ]);
    $this->crud->setModel("App\User");
        $this->crud->addColumn([ // n-n relationship (with pivot table)
       'label' => "Roles", // Table column heading
       'type' => "select_multiple",
       'name' => 'roles', // the method that defines the relationship in your Model
       'entity' => 'roles', // the method that defines the relationship in your Model
       'attribute' => "name", // foreign key attribute that is shown to user
       'model' => "Backpack\PermissionManager\app\Models\Roles", // foreign key model
        ]);
        $this->crud->removeColumns(['password', 'roles', 'assign_user']); // remove an array of columns from the stack
        $this->crud->addClause('whereHas', 'roles', function($query) {
            $query->where('name', 'Student');
        });
    }

    public function index()

    $this->data['crud'] = $this->crud;

    // get all entries if AJAX is not enabled
    if (! $this->data['crud']->ajaxTable()) {
        $this->data['entries'] = $this->data['crud']->getEntries();
    }
    return view('StudentLists', $this->data)
    ->with('userallocation', $userallocation);
    }

    public function prospective()
    {

    $this->crud->hasAccessOrFail('list');

    $this->data['crud'] = $this->crud;
    $this->data['title'] = ucfirst($this->crud->entity_name_plural);

    }
    return view('StudentLists', $this->data)

    ;
    }

   'label' => 'Assigned User', // Table column heading
    ]);
    $this->crud->addColumn([

    }
    return view('StudentLists', $this->data)

    }

    public function assigneduser(Request $request)
    {
        $user_id = $request->id;
        $user = User::firstOrNew(['id' => $user_id]);
        $formdata = $request->all();
        $user->update($formdata);
        return \Redirect::back();
    }

    public function create()
    {
        $this->crud->hasAccessOrFail('create');
        // prepare the fields you need to show
        $this->data['crud'] = $this->crud;
        $this->data['fields'] = $this->crud->getCreateFields();
        $this->data['title'] = trans('backpack::crud.add').' '.$this->crud->entity_name;

        // load the view from /resources/views/vendor/backpack/crud/ if it exists, otherwise load the one in the package
        return view('crud::create', $this->data);
    }
    public function store(StoreRequest $request)
    {
        // insert item in the db
        if ($request->input('password')) {
            $item = $this->crud->create(\Request::except(['redirect_after_save']))->assignRole('Student');
            // now bcrypt the password
            $item->password = bcrypt($request->input('password'));
            $item->save();
        } else {
            $item = $this->crud->create(\Request::except(['redirect_after_save', 'password']));
        }

        // show a success message
        \Alert::success(trans('backpack::crud.insert_success'))->flash();
        // redirect the user where he chose to be redirected
        switch (\Request::input('redirect_after_save')) {
            case 'current_item_edit':
                return \Redirect::to($this->crud->route.'/'.$item->id.'/edit');
            default:
                return \Redirect::to(\Request::input('redirect_after_save'));
        }
        //return parent::storeCrud();
    }

    public function update(UpdateRequest $request)
    {
        return parent::updateCrud();
    }
}

using the above controller (not using ajax table) it works but only if there are any records in that table..
and if i enable the ajaxtable it gives me:
Undefined variable: entry

even if i disable the ajaxtable and if there are no records meeting the criteria i still get the same error..
can anyone point out what am i doing wrong here? :(

found the issue... it was my own jquery where i was getting the id of the user to be edited in the modal window using: {{$entry->getKey()}}
