85-88: Consider using optional chaining for a more concise implementation.While the current implementation is correct, you could make it more concise using optional chaining.
- if (destroyOutsideClickHandler) { - destroyOutsideClickHandler(); - destroyOutsideClickHandler = null; - } + destroyOutsideClickHandler?.(); + destroyOutsideClickHandler = null;src/LumexUI/wwwroot/js/components/popover.bundle.js (1)
1478-1481: LGTM! The null check fixes the reported issue.The changes correctly prevent the "destroyOutsideClickHandler is not a function" error by adding a null check. Setting the handler to null after cleanup is also a good practice to prevent multiple invocations.
However, consider these additional improvements:
- Add error logging when destroy() is called without initialization
- Consider resetting other module state variables in destroy()
Here's a suggested implementation with the improvements:
function destroy() { if (destroyOutsideClickHandler) { destroyOutsideClickHandler(); destroyOutsideClickHandler = null; + } else { + console.warn('Popover.destroy() called before initialization'); } }

85-88: LGTM! The null check fixes the 'destroyOutsideClickHandler is not a function' error.
The implementation correctly prevents the error by checking if the handler exists before calling it, and properly cleans up by setting it to null afterward.
85-88: Verify the fix resolves all error scenarios.
Let's verify that this change resolves all scenarios where the error could occur.
✅ Verification successful
Let me check the implementation details of the destroy method to better understand the error scenarios.
Let me check the initialization and event handling code to understand how the destroyOutsideClickHandler is set up.
Let me check the implementation of createOutsideClickHandler to fully understand the cleanup process.
The fix properly handles all error scenarios
The implementation is correct and handles all error scenarios effectively:
- The
destroyOutsideClickHandleris only assigned during successful initialization - The destroy method safely checks if handler exists before calling
- The handler is properly nullified after cleanup
- The
createOutsideClickHandlercorrectly removes event listeners when called
The cleanup chain is complete with no potential memory leaks or dangling event listeners.
