Element is not currently visible and so may not be interacted with

This page was somewhat helpful, but did not mention the "transform" style needing to be checked. Then I found this fellow using C# who mentioned the transform value. When I put the two together I came up with this solution:

((JavascriptExecutor)driver).executeScript(
   "arguments[0].style.transform = 'none';",
   myFavoriteElement
);

After setting transform = 'none', myFavoriteElement.sendKeys() did not fail with the infamous error:

Element is not currently visible and so may not be interacted with(..)

So I guess we should add transform != 'none' to the list as follows:

• visibility != hidden
• display != none (is also checked against every parent element)
• opacity != 0 (in rc2 this is no longer checked for clicking an element)
• height and width are both > 0
• for an input, the attribute type != hidden
• transform != 'none'

This issue was found using selenium.version = 2.35.0

NOTE: myFavoriteElement was an input type=file generated by the PrimeFaces fileUpload tag. PrimeFaces 4.0 looks like it introduced the transform. Also, when I checked to see what the transform value was before setting it to none, it logged: myFavoriteElement.getCssValue("transform") = matrix(4, 0, 0, 4, -300, 0).

Hope that helps.
