Hi,

I have a similar problem when I try to find a button on a page, which was reported here:

I assume that the problematic code is this:

Code: Select all

private static WebElement GetWebElement(string propertyName, string propertyValue)
{
    var webDocument = Ranorex.Host.Local.FindSingle<WebDocument>($"/dom[@domain='{globalParameter.WebPageUrl}']", new Duration(30000));
    return webDocument.FindSingle<WebElement>($".//*[@{propertyName}='{propertyValue}']", new Duration(30000));
}

My Ranorex version is: 8.1.1
My Chrome version is: 75.0.3770.142

Could you please help us to resolve this problem?

It seems, that the Browser window was not in focus.
After call webDocument.Browser.Activate(); it seems working.

The problem came back after a few successful runs.

It cannot find the button.
No element found for path './/*[@name='Button']' within 3m.

On the screenshot, I see that the Chrome didn't get the focus.
