त्रुटि: कैश घटक घटक के लिए वर्तमान घटक आरएफ अलग है - कोणीय, कोणीय 2-मूलभूत

मैं एक NativeScript Angular 2 एप्लिकेशन विकसित कर रहा हूं।

मेरे पास एक सूची दृश्य है जिसमें एक गुच्छा हैवस्तुओं। इनमें से किसी एक वस्तु के दोहन से एक नया घटक खुल जाता है। सूची में वापस जाने के लिए और सूची में किसी अन्य ऑब्जेक्ट पर प्रेस करने के लिए बैक बटन दबाने के बाद, मुझे निम्नलिखित त्रुटि मिलती है:

मैं इसे कैसे ठीक करूं?

उत्तर:

जवाब के लिए 2 № 1

मेरे पास यह त्रुटि थी क्योंकि विवरण पृष्ठ एक्शनबार में एक ऑब्जेक्ट प्रॉपर्टी का उल्लेख कर रहा था ... (ऐसा लगता है कि जब कार्रवाई बार प्रदान की गई थी, तो यह तत्काल नहीं किया गया)

जवाब के लिए 0 № 2

मैंने अपनी विशेषता में सिर्फ एक * ngIf जोड़ा है ताकि यह सत्यापित किया जा सके कि यह अपरिभाषित नहीं है।

उदाहरण:

<StackLayout *ngIf="example">
<Label textWrap="true" [text]="example.title"></Label>
<Image [src]="example.image" height="100"></Image>
</StackLayout>
