Fix TypeError in IgxTextHighlightDirective when destroyed before initialization #16456

Copilot · 2025-11-13T15:43:25Z

Closes #

Description

IgxTextHighlightDirective throws TypeError: Cannot set properties of undefined (setting 'searchText') when destroyed before ngAfterViewInit() completes. The error occurs because _lastSearchInfo is accessed in ngOnDestroy() → clearHighlight() before being initialized.

// Before: Crashes on early destruction
ngOnDestroy() {
    this.clearHighlight();  // _lastSearchInfo is undefined
}

clearHighlight() {
    this._lastSearchInfo.searchText = '';  // TypeError
}

Changes

Added null guards to all _lastSearchInfo access points:

clearHighlight() - Guard property assignments
highlight() - Return 0 early if uninitialized
ngAfterViewChecked() - Guard condition check
searchNeedsEvaluation() - Return false early if uninitialized

// After: Safe at any lifecycle point
clearHighlight() {
    this.clearChildElements(false);
    if (this._lastSearchInfo) {
        this._lastSearchInfo.searchText = '';
        this._lastSearchInfo.matchCount = 0;
    }
}

Added tests covering early destruction and pre-initialization method calls.

<issue_title>IgxTextHighlightDirective throws TypeError when destroyed before ngAfterViewInit completes</issue_title>
<issue_description>## Description
The IgxTextHighlightDirective throws a TypeError: Cannot set properties of undefined (setting 'searchText') when the directive is destroyed before its view initialization completes. This occurs when components containing the directive are destroyed
during Angular's change detection cycle before ngAfterViewInit() has been called.

The error occurs in the clearHighlight() method which is called from ngOnDestroy(). The method attempts to access this._lastSearchInfo.searchText and this._lastSearchInfo.matchCount, but _lastSearchInfo is only initialized in
ngAfterViewInit(). If ngOnDestroy() is called before ngAfterViewInit() completes, _lastSearchInfo remains undefined, causing the error.

Error Stack Trace:

}

ngAfterViewInit() {
    // ...
    this._lastSearchInfo = {  // Only initialized here
        searchText: '',
        content: this.value,
        matchCount: 0,
        caseSensitive: false,
        exactMatch: false
    };
}
Steps to reproduce

Create an Angular application with components that use IgxTextHighlightDirective (e.g., tree nodes, list items with search highlighting)

Dynamically create and destroy these components rapidly (e.g., routing between views, conditionally rendering with *ngIf)

Ensure the components are destroyed during Angular's change detection before their ngAfterViewInit() lifecycle hook completes

Observe the console error: TypeError: Cannot set properties of undefined (setting 'searchText')

Result

The application throws a TypeError when IgxTextHighlightDirective is destroyed before initialization completes. The error propagates to the global error handler, potentially causing error loops or degraded user experience.

Expected result

The IgxTextHighlightDirective should safely handle being destroyed at any point in its lifecycle, including before ngAfterViewInit() completes. The clearHighlight() method should check if _lastSearchInfo exists before accessing its properties.

Proposed Fix:
 clearHighlight() {
     this.clearChildElements(false);
     if (this._lastSearchInfo) {  // Add null check
         this._lastSearchInfo.searchText = '';
         this._lastSearchInfo.matchCount = 0;
     }
 }
