All Implemented Interfaces:

com.vaadin.flow.component.AttachNotifier, com.vaadin.flow.component.DetachNotifier, com.vaadin.flow.component.HasElement, com.vaadin.flow.component.HasStyle, Serializable, org.springframework.beans.factory.Aware, org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware

public class TimelineAssistantThinkingMessageItem
extends AbstractTimelineItem
implements org.springframework.beans.factory.InitializingBean, org.springframework.context.ApplicationContextAware

Row shown while the assistant is preparing a response. Displays a shimmer indicator, the latest live status, and a history of prior steps delivered by AI tools through AiToolStatusPublisher.

Each AiToolStatusUpdate carries a message and an optional resultSnippet; AiToolStatusUpdate.isCompleted() is true when the snippet is non-blank. Completed past steps are prefixed with a "✓ " check mark and their snippet is rendered next to the base text; in-flight past steps render plain (no check, no snippet).
