[vin]

When i route to a new page with tabs, i am selecting 2nd tab when loading 
But it is always selecting 1st tab and i see script error

From another page

 redirectToBacklog(row: any) {

    console.log('redirect IN', row);

    var getRouteLink = "/project-charts/backlog"

    this.router.navigateByUrl(getRouteLink, { state: { rowDet: row } });

    

  }

if (history.state.rowDet) {

          if (this.tabInstance) {

            this.itemId = history.state.rowDet.itemId;

            this.selItemRow = this.aBacklogs.filter(e => e.itemId == this.itemId)[0];

            this.tabInstance.selectedItem = 1;           

          }

          console.log(' this.state$', this.selItemRow);

        }
