Presever-order=true does not work in selenium-grid

@BeforeTest
@Parameters({"selenium.host", "selenium.port", "selenium.browser", "selenium.url" })
public void startServer(String host, String port, String browser, String url) throws Exception {      
        selenium = new DefaultSelenium(host, Integer.parseInt(port), browser, url);
        selenium.start();
    }

When i run the suite it should invoke startServer() from TestBase -> loginPage() and SignIn() from Login -> clickLinkA() and isTextBoxXXXPresent() from Page1. But manytimes system first invokes mathods from Page1 class and so gets failed (since signIn is not invoked).

Can any one please tell me where i am wrong here. Or any other better way to design. or any alternate for preserve-order

I think this may be issue in TestNG which you can report to TestNg guys. But to overcome your issue, you can include your login & Signin method in your BeforeTest or call it in your test Method in this case clickLinkA. Hope this solves your prblm.

Consider using dependsOnMethods to make sure that one test that depends on another runs after it. You can also set a numeric priority, where the lower numbers run first. The default for priority is 0, so you would only need to set this for tests to run after those that do not have a priority set.
