RadToolBar FindItemByText() getting exception after navigating to second page

[LQKerry]

I am still relatively new to using the Telerik Testing Framework and am still figuring some things out, but this one has puzzled me for almost a day now. I am running a scenario, using MSTest as the unit test framework and IE 8, to log a user in and then log out. Simple, right? Well, I can get the user logged in without issue, but after the browser navigates to the page after successful log in I will get an error trying to call the RadToolBar FindItemByText() method. I can access the "Log Off" button I am looking for if I use a more direct approach as displayed in my code example, but I really like the features that the RadControl wrappers provide. What I find the most confusing about this, is if I find the RadToolBar element (common control on the Master page for the project) and perform a FindItemByText() method prior to logging in it works without getting the error.

Thanks for any help!

The following is my code and then the details of the error captured by VS2012 debugger.

string userName = TestContext.DataRow["Username"].ToString();

ActiveBrowser.NavigateTo("~/User/LogInPage.aspx");

HtmlFindExpression untbExpr = new HtmlFindExpression("id=?RadTextBoxUserName_wrapper");
ActiveBrowser.WaitForElement(untbExpr, 30000, false);
RadTextBox usernameTb = ActiveBrowser.Find.ByExpression<RadTextBox>(untbExpr);
usernameTb.Clear();
usernameTb.TypeText(userName);

HtmlFindExpression lbExpr = new HtmlFindExpression("id=?RadButtonLogin_input");
ActiveBrowser.WaitForElement(lbExpr, 30000, false);
RadButton loginButton = ActiveBrowser.Find.ByExpression<RadButton>(lbExpr);
loginButton.MouseClick();      //Navigates to ~/Default.aspx but authenticated.

//Throws error
HtmlFindExpression expr = new HtmlFindExpression("id=?RadToolBarMain");
ActiveBrowser.WaitForElement(expr, 30000, false);
RadToolBar tb = ActiveBrowser.Find.ByExpression<RadToolBar>(expr);
RadToolBarItem lob = tb.FindItemByText("Log Off");

//WORKS!!!
//HtmlFindExpression loButton = new HtmlFindExpression("title=^Log Off", "class=rtbWrap");
//ActiveBrowser.WaitForElement(loButton, 30000, false);
//HtmlAnchor lob = ActiveBrowser.Find.ByExpression<HtmlAnchor>(loButton);
//lob.MouseHover();

Hello Kerry,

I’m sorry to hear that you are running into this issue. As you may be aware, our framework comes with a set of translators for gaining access to the advanced attributes of the controls. We've made some improvements to those translators in our latest internal build and I believe those changes will address your issue. You can upgrade to version 2012.2.1527 by logging into your Telerik account and accessing this link: Public URL
