public class ViewCurrentRecord

extends DataWebBeanImpl

The ViewCurrentRecord Data Web Bean displays a read-only version of the current record of a View Object's RowSet.

JDeveloper's JSP Element wizard instantiates the ViewCurrentRecord class in a jsp:useBean tag in a .jsp file. Along with the class, the wizard also includes an ID and a scope declaration set to request. If you change the scope to any other value, you will have to handle possible multithreading issues.

The definition of ViewCurrentRecord provided by the wizard includes these methods: setUseRoundedCorners, setShowRecordNumbers, setReleaseApplicationResources, initialize, and render. For example,

 <jsp:useBean   class="oracle.jbo.html.databeans.ViewCurrentRecord"
                         id="vcrMaster"  scope="request" >
 <%

     vcrMaster.setUseRoundedCorners(true);
     vcrMaster.setShowRecordNumbers(true);
     vcrMaster.setReleaseApplicationResources(false);
     vcrMaster.initialize(application,session, request,response,out,
                       "package3_Package3Module.DeptView");
     vcrMaster.render();
 %>
 </jsp:useBean>
 

The value assigned to the setReleaseApplicationResources method determines whether the Application Module is released after ViewCurrentRecord Data Web Bean processes it. Typically, the value should not be set to true unless this is the last Web Bean to be processed in the JSP page.
