+[routerLink] doesn't have ANY change detection. This means that if a value comes in slower than when it gets instantiated by Angular, then it won't work, below I have two solutions
+
+Example Problem:
+```html 
+    <a [routerLink]="['/some-route', valueThatIsTooSlowThatWillBeNullOrUndefined]">
+
+```
+
+Solution 1:
+
+```html 
+    <a *ngIf="value" [routerLink]="['/some-route', value]"/>
+```
+
+Solution 2:
+```html 
+    <a (click)=navigateToRoute(value.id)/>
+```
+
+```typescript
+    public navigateToRoute(id: number) {
+        this.router.navigate(['/some-route', id]);
+    }
+
+```
