Cannot use in operator to search for __eventList in null in Dialog

I am encountering an issue with the Syncfusion Angular Dialog component. When I attempt to close the dialog, I receive the following errors:


TypeError: Cannot use 'in' operator to search for '__eventList' in null

TypeError: Cannot read properties of null (reading 'parentElement') at checkInputValue (input.js:151:39) at Object.setValue2 [as setValue] (input.js:534:9) at DropDownList2.destroy (drop-down-list.js:3828:19) at PagerDropDown2.destroy (pager-dropdown.js:164:37) at ModuleLoader2.clean (module-loader.js:57:55)

The second issue occurs intermittently, not every time the dialog is closed.


I have created a working example on StackBlitz that demonstrates the problem:

https://stackblitz.com/edit/stackblitz-starters-vtxaom?file=src%2Fapp%2Fdialog-component%2Fdialog-component.component.html


Steps to Reproduce

  1. Open the dialog component.
  2. Perform some actions inside the dialog (if any).
  3. Attempt to close the dialog.
  4. Observe the console for errors.

please help me fix this bug as soon as possible. thanks 

Best Regards,
Buddhi.

Hi Buddhi,


We are glad to announce that our weekly patch release (26.2.9) has been rolled out. We have included the fix for this “Script error thrown in switch when open and closing dialog component” issue in this release. So, we suggest you upgrade our Syncfusion packages to our latest version to resolve this issue on your end (26.2.9)


Root cause: The underlying reason for the problem is that we failed to check the null condition for the switch wrapper element before destroying the switch component.


Sample link: https://stackblitz.com/edit/stackblitz-starters-3fjc2f?file=src%2Fcomponent%2Fswitch-box%2Fswitch-box.component.html


Release notes: https://ej2.syncfusion.com/angular/documentation/release-notes/26.2.9?type=all#switch


Package link: https://www.npmjs.com/package/@syncfusion/ej2-angular-buttons


Get back to us if you need any further assistance on this.
