Trouble accessing object property within view in Ionic 2

While working on a tutorial using Ionic 2, I've encountered an issue where I cannot access an object property in the view. Here's an example:

// TypeScript file
export class MyClass {
     myObject: any;

     constructor() { }

     ionViewDidLoad() {
         this.myObject = getData(...);
     }
}

// HTML
<p>{{ myObject.property }}<p>

The result shows: "Cannot read property 'property' of undefined at CompiledTemplate.proxyViewClass..."

Interestingly, I am able to log my object and see that it contains the desired property. Even when I try this:

<p>{{ myObject | json }}</p>

The JSON object is displayed with its property intact... It seems like accessing the property within the interpolation brackets is causing the issue.

Answer №1

The issue at hand arises when the response from the getData(...) function takes longer than expected, causing the template to access properties of an object that is potentially undefined.

To resolve this problem, you can utilize the Safe Navigation Operator for secure navigation:

<p>{{ myObject?.property }}</p>
