Selected on Init

I need to select on init some rows, so I set on init some rows to this.selected. All good, but when I click + shift I unselect rows, Event selected says that I select none;

     <ngx-datatable
        #table 
        class="material"
        [rows]="rows"
        [columns]="columns"
        [selected]="selected"
        [selectionType]="'multi'"
        [columnMode]="'force'"
        [headerHeight]="24"
        [footerHeight]="0"
        [rowHeight]="40"
        [scrollbarV]="true"
        [scrollbarH]="false"
        [messages]="{emptyMessage: 'No items have been added to the collection'}"
        (select)='onSelect($event)' 
        (page)='onPage($event)'
        (recalculate)=recalculate($event) >

         <ng-template #editTmpl let-value="value" let-row="row" let-i="index" >

          <span 
                  *ngIf="!editing[row.$$index + '-name']">
                  {{value}}
            </span>
            <input #input autofocus type="text"
                  (blur)="updateValue($event, 'name', value, row, input)" 
                  (keyup.enter)="updateValue($event, 'name', value, row, input)"
                  [hidden]="!editing[row.$$index + '-name']" 
                  [value]="value"
                  [class.error]="row.error"
            />
            <img class="rename-icon" src="assets/images/rename.png" 
                  (click)="onRename( input, row )"
                  [hidden]="!checkingPermission(row, 'Update')"   />
         <!--         editing[row.$$index + '-name'] = true-->

         </ng-template>

         <ng-template #dateTmpl let-value="value" let-row="row" let-i="index">
           <time>{{value | dateFormat }}</time>
         </ng-template>

          <ng-template #boolTmpl let-value="value" let-row="row" let-column="column" let-i="index">
              <img class="validStatus-img" src="./assets/images/{{value?column.trueImg:column.falseImg}}"  />
              <span>{{value ? "Ok" : "Invalid"}}</span>
          </ng-template>

      </ngx-datatable>

Datatable 8.0.0 Angular 4

I found a way to make it work for my scenario - the key is to specify [rowIdentity]="rowIdentity" at the datatable html object. That way the component can compare the row in [rows] and [selected] and REALLY mark the “pre-selected” rows. Works like a charm, but the documentation is quite shallow on this (https://swimlane.gitbook.io/ngx-datatable/api/table/inputs#rowidentity).

I have solved it by searching the DOM for the checkbox and clicking on them. Is working

I am having the same problem when storing the selected array in service to preserve it when users navigate to other views.
