Hi, this is using Cambalache 0.10.3 on Guix System (guix 77e768a).
The problem seems limited to GTK 4 projects. GTK 3 worked for me.
STEPS TO REPRODUCE
1. Launch Cambalache
2. Create a new GTK 4 project
2.1. Click "Create a new project" button
2.3. Add project name (e.g. test)
2.4. Choose location
2.5. Select Gtk 4 as Toolkit target
2.6. Add UI file name (e.g. window.ui)
2.7. Click "Create" button
EXPECTED RESULT
☑ The workspace is loaded
☑ Clicking Toplevel → GtkApplicationWindow add a new app window to the
workspace
UNEXPECTED RESULT
☒ The workspace loads with an error:
~~~
Workspace process error
Stopping auto restart
~~~
☒ I can't add any GUI component to the workspace. Clicking Toplevel →
GtkApplicationWindow adds the window to the project tree but not to the
workspace
ADDITIONAL INFORMATION
Starting Cambalache from a terminal and following the steps to reproduce I can
see the following error:
