org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/TemplatePreferencePage.java
if (path == null)
			return;
		
		try {
			fTemplates.addFromFile(new File(path));
			
			fTableViewer.refresh();
			fTableViewer.setAllChecked(false);
			fTableViewer.setCheckedElements(getEnabledTemplates());
		} catch (CoreException e) {			
			openReadErrorDialog(e);
		}

		export(fTemplates);	
	}
	private void export() {
		IStructuredSelection selection= (IStructuredSelection) fTableViewer.getSelection();
		Object[] templates= selection.toArray();
		
		TemplateSet templateSet= new TemplateSet();
		for (int i= 0; i != templates.length; i++)
			templateSet.add((Template) templates[i]);
		
		export(templateSet);
