Example 1 with PartialMarkupRenderer

use of org.apache.tapestry5.services.PartialMarkupRenderer in project tapestry-5 by apache.

the class RenderCommandComponentEventResultProcessor method renderMarkup.

/**
 * As a filter, this class does three things:
 * <ul>
 * <li>It creates an outer element to capture the partial page content that will be rendered</li>
 * <li>It does setup and cleanup with the {@link AjaxFormUpdateController}</li>
 * <li>It extracts the child markup and stuffs it into the reply's "content" property.</li>
 * </ul>

    // so those must be enclosed in a root element.
