Ion-img Cannot read property 'isImgsUpdatable' of null


#1

I have the following code to set image on header:
<ion-header> <ion-navbar> <ion-row> <ion-col width-10> <ion-img src="./assets/img/icon.png"></ion-img> </ion-col> <ion-col> <ion-img style="margin-left: 40px;margin-right: 50px" src="./assets/img/Header.png"></ion-img> </ion-col> </ion-row> </ion-navbar> </ion-header>
I am getting the below errors while doing ionic serve

My ionic info:
Your system information:

Cordova CLI: 6.4.0
Ionic CLI Version: 2.2.1
Ionic App Lib Version: 2.2.0
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Windows 7
Node Version: v6.8.1
Xcode version: Not installed

NOTE
The code works inside ion-content.
It also works if I use just img instead of ion-img.
Am I missing something in ion-img or is this a bug?


#2

Anyone has any idea?
So I cannot use ion-img in header?


#3

From your code I can’t find a variable where you are using the property isImgsUpdatable!
This error seems to be coming from your Javascript code, so please post that code as well or check if you are using this property on a variable which is null!

In general, your error does not seem to be related to the header image because you don’t load it dynamically!


#4

I am not using isImgsUpdatable. ion-img does in the Ionic code.
But for some wierd reason it throws error within the header but works fine in ion-content.
Checked in Ionic github.


#6

ion-img should only be used with virtual scroll.

isImgsIpdatable is a method from Content, so only with ion-content

@LAFONT Thank you. That explains it…
