Hi Victor,
Have you seen if the path to the object is always the same or constantly chaging?
Try this peace of code to see if you can find the object in question, if you do is probably a problem with your name mapping properties of the object. You can use this code to do anything you need on the object, just change the "click()" for something else you need.
function clicarNoComponente(propriedade,texto)
{
// Using the Find method
var myObj = Sys.Browser("iexplore").Page("*").NativeWebObject.Find(propriedade,texto);
// Checks if the button exists
if (myObj.Exists)
{
myObj.Click();
waitForLoading();
}
else
Log.Error("Can't find the object","");
}
Espero ter ajudado.
