Example 6 with MarkupElement

use of org.apache.wicket.markup.MarkupElement in project wicket by apache.

the class StyleAndScriptIdentifierTest method postProcess.

/**
 * https://issues.apache.org/jira/browse/WICKET-4453
 *
 * This test wraps rawMarkup in org.apache.wicket.util.string.JavaScriptUtils#SCRIPT_CONTENT_PREFIX
 * twice - once in Markup.of() and second in the explicit call to StyleAndScriptIdentifier.postProcess().
 * The second time it realizes that the element body is already wrapped and skips it.
