Details

In java_client code, WebElement parameter is casted to RemoteWebElement.
It makes hard to create proxy object for WebElement (like Selenide and probably some other frameworks do).

Actually only method getId() is used. This method is declared in interface HasIdentity.

This pull request changes few places where WebElement is casted to RemoteWebElement so that it's not casted to HasIdentity instead of RemoteWebElement.

Old code:

new ActionParameter("press", (RemoteWebElement) el);

new code:

new ActionParameter("press", (HasIdentity) el);
