PanelBinding and JBO-35001

Question

Hello, we got a problem.
We are using ADF with JClient-technologie and MDI Client-Server forms.
We build a JPanel with the JDeveloper-Wizard and put that in an JInternalFrame which is invoked by a JDesktopPane. That works...
But if we create the same JInternalFrame twice we get the exception JBO-35001. I read the workaround in the JDeveloper-Releasenotes but that does not fit to our problem.
Has anybody a possible solution to that problem ???
Here are some lines of the sourcecode...
MasterMDI.java
public static BindingContext ctx = new BindingContext();
public DepartmentsPanel panel;
public static void main(String args[])
try
// bootstrap application
JUMetaObjectManager.setBaseErrorHandler(new JUErrorHandlerDlg());
JUMetaObjectManager mgr = JUMetaObjectManager.getJUMom();
mgr.setJClientDefFactory(null);
//BindingContext ctx = new BindingContext();
ctx.put(DataControlFactory.APP_PARAM_ENV_INFO, new JUEnvInfoProvider());
ctx.setLocaleContext(new DefLocaleContext(null));
HashMap map = new HashMap(4);
map.put(DataControlFactory.APP_PARAMS_BINDING_CONTEXT, ctx);
mgr.loadCpx("DataBindings.cpx", map);
new MasterMDI();
catch(Exception ex)
JUMetaObjectManager.reportException(null, ex);
System.exit(1);
public void createDepartmentsPanel()
panel = new DepartmentsPanel();
panel.setBindingContext(ctx);
panel.revalidate();
// InternalFrame
JInternalFrame iFrame = new JInternalFrame("Departments", true, true, true, true);
// BorderLayout...
iFrame.getContentPane().setLayout(new BorderLayout());
// Center
iFrame.getContentPane().add(panel, BorderLayout.CENTER);
// show
iFrame.pack();
iFrame.setVisible(true);
// JDesktopPane
masterPane.add(iFrame);
If we call the method createDepartmentsPanel for the first time it works... but not the second time...???
I've also tried to call the release() - Method of the panel but this does not work...
HAS ANYBODY A SOLUTION ???
