ERROR TypeError: Cannot read property 'unit' of null

Hi,

I'm not able to use shadow when inside of a RadListView and ng-template. Always throw that error..

Any workaround?

Thanks

this is how my listview item looks

<ng-template tkTemplateKey="error" let-item="item.payload">
    <Stacklayout class="light-background" margin="15, 15, 20, 15" shadow="7">
        <Label class="slight-dark-color" margin="10" [text]="item.errorText"></Label>
    </Stacklayout>
</ng-template>

Hi @TheOriginalJosh - Sorry to bother you but I wonder if you will have any idea how can we fix it?

[bzaruk]

@devlfm -

I was able to workaround this issue with creating shadow to the element dynamically on itemLoading event.

Like this: HTML:

<RadListView class="full-stretch" [items]="items" (itemLoading)="onItemLoading($event)">
</RadListView>

TS:

public onItemLoading(args: ListViewEventData) {
    Shadow.apply(args.view, { elevation: 7 });
}

@shabib3 How did you get access to Shadow ? What import did you use?

[darkmantle]

Figured that out, yet it doesn't work for me either. There is still no shadow in the ListItem - even when removing all styling as I had a background set before.

I have the same issue with nativescript-fresco. I think this relates to RadlistView component. Any workaround?
