UML Attributes are not visible on Linux CentOS 9
CentOS Stream 9 Gnome 40.4.0 Weyland windows manager
As presented on the following picture UML attributes are not visible for classes (operations and attributes as well)

IIUC, you mean: "the UML properties panel", in stead of "UML attributes"
Hello, If the operations/attributes are created in explorer you have to unmask them by drag and drop in diagram. The problem is reported to developers.
@mvdw yes, the properties panel is not visible. You cannot edit them. This is how it looks on Windows.

Hi mkwpisz,
Do you have the webkit2gtk3 lib installed ? It is mandatory for Modelio to work correctly...
[root@localhost ~]# dnf list installed | grep webkit2gtk3
webkit2gtk3.x86_64 2.38.5-1.el9 @appstream
webkit2gtk3-jsc.x86_64 2.38.4-1.el9 @appstream
