Hi,
with the exact same test case as here : https://www.fusetools.com/community/forums/bug_reports/property_default_value
you can’t run fuse preview
with this code, you need to launch the preview then add the code. Otherwise you’ll get :
.build/Simulator/Local1/Cache/GeneratedCode/MyComponent.g.uno(19,5): E3114: There is nothing named 'Fuse_Elements_Alignment' accessible in this scope. Are you missing a package reference?
Cheers
