controller unable to toggle view: %w

Error message

controller unable to toggle view: %w

What it means

TUI controller error from ToggleView(): it switches focus between the filetree view and the layer view, and wraps a failure of gocui SetCurrentView() for whichever destination view applies. Note the subtle behavior: if the current view is nil or is the Layer view it targets Tree, otherwise it targets Layer.

Solutions

1. Wait until the full UI (including the filetree) is drawn before toggling views.
2. If triggered right after closing the filter, retry the toggle — transient focus races usually clear on the next keypress.
3. Resize the terminal to a normal dimension and re-run.
4. Upgrade dive; report upstream with a keypress transcript if reproducible.

When it happens

Trigger: Pressing the toggle-view keybinding when the destination view (usually Tree, the largest pane) has not been created by gocui yet, or was destroyed by a layout pass; also reachable from ToggleFilterView hiding the filter and re-focusing.

Common situations: Pressing Tab/space (toggle binding) immediately at startup; toggling while the filter view is closing (error 32 chains through here); degenerate terminal sizes.
