Object IllegalStateException Problem

Show all headers | View raw

Hello,

I am working on a Java application, and run into the following
exception when trying to save my Network Configuration Parameters. I
have been looking at the execution stack trace for clues to the
problems.

This is the save() method that calls the different objects to save the
individual Configuration<Types>:

    public void save() throws XmlException, IOException {
        if (logger.isDebugEnabled()) {
            logger.debug("Saving systemwide config...");
        }

        if(!systemwideConfiguration.equals(null)) {
        	systemwideConfiguration.bufferedSave();
        }

        if(!rtdbConfiguration.equals(null)) {
        	rtdbConfiguration.bufferedSave();
        }

        if(!localeConfiguration.equals(null)) {
        	localeConfiguration.saveAsCommitted();
        }

        if(!hmiAccessMgrModel.equals(null)) {
            hmiAccessMgrModel.save();
        }

        if (!CommunicationManager.getInstance().getIsDNA()){
            runtimeGUIConfiguration.bufferedSave();
            eventLoggerConfiguration.bufferedSave();
            dhcpModel.save();
        }

        if (CommunicationManager.getInstance().getIsDNA()){
        	if(!timeSyncModel.equals(null)) {
        		timeSyncModel.save();
        	}
        }

        if (logger.isDebugEnabled()) {
            logger.debug("Saving systemwide config...completed");
        }

        setModified(false);
    }

Here is the corresponding stack trace:

java.lang.IllegalStateException: Please load a version of an object
before saving!

$SaveAction.doLongOperation(SystemwideController.java:272)
      at com.gepower.d400.swing.BusyThread.run(BusyThread.java:103)

Now, I am thincking that the command:

hmiAccessMgrModel.equals(null)

is causing the problem and should be re-written as:

hmiAccessMgrModel == null

Suggestions as to what the problem might be ?
