Combobox defaultselectedItems from collection is not working first time but works second time onwards

[Komal1]

I am trying to have a combobox with multi select . The DefaultSelectedItems come from a collection. But this is not working on the first click, I get only one of the multiple selections first time and it works fine from second time onwards.

I have a combobox named Rating. Its Items are [1,2,3,4,5]

DefaultSelectedItems : 

ForAll(
       RatingSelected,
       {
           Value: Value
       }
)

This is working fine from second time(i.e First time when u open the app it doecnt work, but when u navigate to other pages and come back it works) but doesnt work the first time.

@Komal1 I think the first time your "RatingSelected" table might be empty that's the reason where your Defaultselected items must not be loaded.

Collection has data. Since it is added on onVisible property of the page.

@Komal1 can you try adding just the collection rather than forall function.

That doesnt work either. This post has more info
