Overview

Gem-default component rendered when an action or partial-render fails and no user-declared recovers entry matches. Verbose mode shows the exception class and message; non-verbose shows a generic message. Users override by setting Weft.configuration.error_component or by declaring their own recovers chain.

Doubles as the default recovery frame for SSE push failures: the Router injects :attempts_remaining only on that path, so its presence switches the build into push shape — a countdown notice while the stream retries, then a stopped notice with a reopen button on the final frame.

#tag_name ⇒ Object

Adopt the failing component's wrapper tag when the Router injected :component_tag — a div swapped into a 's position is invalid table content; a error row is not.
