Eclipse Plug-in:Focus lost after activating a view via (controlSite.doVerb(OLE.OLEIVERB_INPLACEACTIVATE));

I have a view which is initialised via OleControlSite and invoked via OleAutomation. It is actually a 开发者_运维知识库media player which I call in a view after user right clicks the file and calls Play in the context menu. Whenever I play a file by first right clicking and calling Play, it plays absolutely fine. The problem is when user displays the view before doing a right click(Window->Show View->Other->MyView) and then tries to do a right click and Play, at this point of time ISelection returns null and hence nothing plays.

 IWorkbenchPage iwPage=PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
             ISelection selection=iwPage.getSelection();

The problem is the selections somehow loses focus if the view has been invoked in the fashion described.

This is how the view is initialised when the plugin is loaded

public void createPartControl(Composite parent) {
        frame = new OleFrame(parent, SWT.APPLICATION_MODAL);
        //      OleControlSite controlSite;
        try {
            controlSite = new OleControlSite(frame, SWT.APPLICATION_MODAL,"WMPlayer.OCX.7");
            controlSite.doVerb(OLE.OLEIVERB_INPLACEACTIVATE);           
            oleAutomation = new OleAutomation(controlSite);
            makeActions();
            fillActionBars();           

        } catch (SWTException ex) {

            MessageBox box = new MessageBox(getSite().getShell(),SWT.ICON_INFORMATION);         
            box.setMessage("Failed to Initialise Media Player.");
            box.setText("Error");
            box.open();                     
            ex.printStackTrace();
            return;
        }
    }

Is there a way where we can force the focus to the Project Explorer where the current file is selected ?
