selenium - waitForCondition gives missing ; before statement error -

i've looked @ examples , still have problem using waitforcondition. here code.

webdriverbackedselenium seleniumwd = new webdriverbackedselenium(driver, "http://www.x.com");  seleniumwd.waitforcondition("seleniumwd.iselementpresent(\"fullname\");", "5000"); 

i error: seleniumwd not defined. changed to:

webdriverbackedselenium seleniumwd = new webdriverbackedselenium(driver, "http://www.x.com");  seleniumwd.waitforcondition("boolean ok = seleniumwd.iselementpresent(\"fullname\");", "5000"); 

and error: missing ; before statement

it seems using selenium js object selenium 2/ webdriver based test. instead of using webdriverbackedselenium should use expectedcondition , wait classes provided webdriver. in case, assuming fullname id of element waiting, code should this:

webelement element; expectedcondition<boolean> e = new expectedcondition<boolean>() {     public boolean apply(webdriver d) {         element = d.findelement(by.id("fullname"));         return boolean.true;     } };  wait<webdriver> w = new webdriverwait(driver, timeoutinseconds); w.until(e); 

this big piece of code, should consider utilizing page objects pattern 1 of best practices writing selenium tests. example page contains field this:

public class mypage {     @findby(id="fullname")     private webelement fullname;      public mypage(webdriver driver) {         pagefactory.initelements(new ajaxelementlocatorfactory(driver, 15), this);     }      public void setfullname(string value) {         fullname.clear();         fullname.sendkeys(value);     } }
