Current Behavior

• When using the IPC to listen to i3 events...
• ... and moving a workspace (of an output with no other workspaces) to a different output...
• ... the emitted workspace:init event references the moved workspace.

Expected Behavior

• ... the emitted workspace:init event references the newly created workspace on the output from which the old workspace has been moved away.

Reproduction Instructions

• Have multiple outputs set up side by side
  • Left output with empty workspace 1
  • Right output with empty workspace 2
• Have an application which logs the workspace events running somewhere (not on right output)
• Focus the right output
• Use a keybinding to move the entire workspace to the left
  • bindsym $mod+Control+Left move workspace to output left
• Observe event output: the current field lists workspace 2 instead of a new one (3?).

Environment

Suspected code

Looking at this line ipc_send_workspace_event("init", ws, NULL);, it seems that instead of the newly created workspace (not referenced by variable here) the "init" event is fired with the current workspace (ws).
