Typically, dangling menu commands are used for creating new target elements. In such cases, the target class is given in the <code>newTarget</code> parameter, and the default behavior is to create the new target element instance and connect it to the source port. Otherwise, the default behavior is to execute the selected command as a standard command signal (see <q ref="core.lib:Global!SIGNAL">SIGNAL</q> macro). The behavior can be extended to support custom commands that depend on other classifying parameters.(c) SAP AG 2003-2006. All rights reserved.
