Children templates attributes connot be override

Unity Engine

Hello

I’m currently trying to reproduce something working in unity version 2021.3.9f1, in the new version 2023.2.11f1.

I try to override attributes of an custom element inside a template (The template are Card.uxml, and the attributes trying to be override are inside CardPatcher element)

I’m currently not able to override attributes of template n < -1 (I can override direct elements of an instantiated template, but i cannot override attributes of an sub/children template inside an instantiate template)

You can see the issue in the screenshots.

In my sample :

  • I have an instante of Card.uxml template directly inside my current UXML
  • I have an instante of ButtonCard.uxml template directly inside my current UXML (ButtonCard are just a button with an instante Card.uxml of template inside it)

Result : In my direct instante of Card.uxml i can override attributes of my CardPatcher BUT i cannot do the same thing for the Card.uxml inside the ButtonCard.uxml instante.

Can you give me information about this regression ? And if it’s a normal issue or if it’s gonna to be fix ?

Thanks

PS : I know there are a limitation in the 2021.3.9f1 about this cas. Indeed if the override element are present a multiple time inside a template (so many element with the same name) all elements are override with the same value.

Hello. The issue was fixed in most versions. The fix for 23.2 is still pending but it should land soon. You can track the progress here: Unity Issue Tracker - Cannot override UXML Attributes when it&#39;s multiple levels deep in the Hierarchy
