List disable virtualization property
Question

Hello guys.


So i was developing a list with tags inside a gallery widget in a mobile app and i was confronted with a strange behavior where i had blank tags occupying space. After some search i found out that i had to add an extended property to the list: 'disable-virtualization: true'.


It seems that this behavior is rather old and Outsystems is working on it since 2017, at least, as you can see from this post: https://www.outsystems.com/forums/discussion/22906/blank-list-item-on-carousel-mobile/


Is there any improvement regarding this issue?

Can you upload a sample that shows your issue? What version of the platform are you using? What UI framework? The more information you can provide - the easier it will be to give an accurate response.


Thanks

Hello Stacey.


Thank you for your response.

I don't believe it matters the platform i'm working with since this issue is rather old, as i pasted a post from 2017 in the original message with the same issue but with Carousel widget and not Gallery widget.

Moreover, Outsystems itself says that when using a List inside the Gallery widget, the extended property 'disable-virtualization' needs to be 'True' since the Silk UI Framework (https://success.outsystems.com/Documentation/SILK_UI_Framework/03_Building_UI_Through_Pattern_Composition/Using_Silk_UI_Patterns/Gallery_Pattern).

And the link for the version 11 of the platform: https://success.outsystems.com/Documentation/11/Developing_an_Application/Design_UI/Patterns/Using_Mobile_Patterns/Gallery_Pattern


I just want to know if Outsystems is doing something regarding this issue or we need to keep adding the extended property?

Hi Rafael,

I believe that outsystems working on that problem,

Can you verify this posto, this is related to your problem, you can need to use this property, when list behaves differently in your list.

Hello,

I had the same issue, but in my scenario I had to Hide some itens from the list, because we are doing all pagination in the front-end and we cant maintain it in a data base... so when my records were "hide" they still had the same invisible height.

Thanks to help me us.
