JavaHelp initialization problem

Question

In my project, I used JavaHelp to create project help function. The following is party of HelpVolumeC.java source code.
Here I used main thread to initialize main gui, at that time used another thread to invoke HelpVolumeC.getHvcInstance().
at first time java help gui cannot be displayed. However when reinitialize main gui, then java help gui is ok.
Somebody has meet this kind of issue? Could give me some advise? thanks!
Here DefaultHelpBroker.initPresentation() is invoked in the second thread.
I think it maybe when you use helpbroker, if it is not initialized completly, it will not be used correctly.
that mean when you use helpbroker, it must be initialized completly. I dont know am I right.
party of initializing of main gui in main thread
// Set the plugin
MjmController.setPlugin(this);
// Create the controller
mjm = MjmController.getPluginInstance();
if (mjm != null) {
_hvc = HelpVolumeC.getHvcInstance();
// have to put this here, so we make sure it queued after the panel
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
running = mjm.isRunning();
if (mjm.getFrameParent() != null) {
mjm.getFrameParent().toFront();

Yes u cannot do a Init after a Full.
Make the Full Load a Repair Full.
Se 38 - Source Code - RSSM_SET_REPAIR_FULL_FLAG
Give the ODS name , Datasource & Source System n Make it Reparir Full
Have a look at this note : Note 689964 - ODS object: Switching from a full to delta upload
If this has to be done before loading - U can jst flag the Repair Full feature in Infopackage - Scheduler - Repair Full.
