```
    Description copied from interface: ComponentResourcesCommon
    
    Triggers a component event. A search for an event handling method will occur, first in the component, then its container, and so on. When a matching event handler method is located, it is invoked. If the method returns a value, the value is passed to the callback (if callback is null, then it is an error for a method to return a non-null value). Resolution of event type to event handler methods is case insensitive.
    
    Specified by:

    Parameters:
    
    eventType - event type (as determined from the request, or otherwise by design)
    
    context - the context (as extracted from the request, or provided by the triggering component); these values may be provided to event handler methods via their parameters (may not be null)
    
    callback - the handler to be informed of the result, or null if the event is a notification that does not support return values from event handler methods (the value true is allowed even if the handler is null).
    
    Returns:
    
    true if any event handler was invoked (even if no event handler method returns a non-null value)

```
public void render(MarkupWriter writer,
                   RenderQueue queue)
```
    Description copied from interface: RenderCommand
    
    Invoked on an object to request that it render itself. This involves a mix of invoking methods on the writer, and queueing up additional commands (often, representing children of the object that was invoked) to perform additional rendering. In this way, rendering is a tail recursive algorithm, but is not implemented using tail recursion.
    
    Specified by:
    
    render in interface RenderCommand
