Calling organize imports programmatically

Question

I'm trying to execute 'OrganizeImports' programmatically on files that I'm editing programmatically. My code looks like this:

    final ICommandService cmdService = (ICommandService)PlatformUI.getWorkbench().getService    (ICommandService.class);
    if (cmdService != null) {
        final Command cmd = cmdService.getCommand(IJavaEditorActionDefinitionIds.ORGANIZE_IMPORTS);
        final ExecutionEvent execEvt = new ExecutionEvent(cmd, Collections.EMPTY_MAP, compileationUnit, null);

        PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage();
        ResourcesPlugin.getWorkspace().

        Display.getDefault().syncExec(new Runnable() {
            @Override
            public void run() {
                try {
                    //cmd.executeWithChecks(execEvt);
                    cmd.execute(execEvt);
                } catch (Exception e) {
                    getLogger().severe("organize imports failed: " + e.getMessage());
                }
            }

My problem is that OrganizeImportsAction executes on the current selection which is not the same as the compilation unit I'm editing. I would like to set the selection programmatically on the compilation unit but I don't know how to do that. Or maybe there is another way to trigger OrganizeImports.

thanks, stefan

May be this test ui.org.eclipse.jdt.ui.tests.quickfix.CleanUpTest class could offer some clue.
It is based on the enable method in ui.org.eclipse.jdt.ui.tests.quickfix.CleanUpTestCase and on the org.eclipse.ltk.core.refactoring.PerformChangeOperation class.

You can see PerformChangeOperation invoked ink the class org.eclipse.ltk.ui.refactoring.RefactoringWizard.
