  Hello,
  
  I am using Wijmo Library 5.20211.781 with ASP.NET.
  
  In one of the screen I use wijmo Tab which is working as expected in stage and prod environment but not working on a site which use office 365 as proxy server to access intranet application.
  
  Error in Console:

          if (PaymentTab != null) {
              PaymentTab.dispose();
          }
          PaymentTab = new wijmo.nav.TabPanel('#PaymentTabs', {
              selectedIndexChanged: function (e) {
                  try {
                      _CurTab = e.selectedIndex;
                      if (_CurTab == 1) {
                          InitializeCheckTabControls();
                      } if (_CurTab == 2) {
                          $(".divPaypalIframe").hide();
                          $(".PaypaldrpDIV").show();
                          InitializePayPalTabControls();
                          //LoadPayPalIframe();
                      }
                      SubmitButtonStatus();
                  }
                  catch (e) {
                      console.log(e);
                  }
              }
          });
  
  

  Same code is used and same server not sure why it’s not working in one.
  
  Please suggest if I am doing it wrong.

  Thank you

  Hi,
  
  As per the error message, it seems that the TreeView is unable to get the content in the order as it required.
  
  Please check the DOM and check if the DOM is same as defined for the TreeView host as defined in the code.

  Also, please share the steps to host the application on the same environment with the environment detail.
  
  It would be better if you may share the demo sample.

  Regards,
