I have an IDOMNode
nsCOMPtr_IDOMNode elementNode;
from which I can get the node name without problems ("INPUT", "FIELDSET", ...)
nsString strName;
elementNode->GetNodeName(strName);
Since Gecko 17 I have the problem, that I cannot get the HTML Input Element Interface for this node:
nsCOMPtr<nsIDOMHTMLInputElement> pHTMLInputElement;
pHTMLInputElement = do_QueryInterface(elementNode);
if(pHTMLInputElement) {
This works fine with < Gecko 16. Any Ideas or known bugs? Did something change between Gecko 16 to 17?

The IID of nsIDOMHTMLInputElement changed from Gecko 16 to Gecko 17. You
are probably compiling against headers for Gecko 16.

Additional infos:
- Tests on Windows 7
- Firefox 17.0
- do_QueryInterface(elementNode, &error); yields NS_ERROR_NO_INTERFACE (0x80004002).
Why didn't I get here the interface since Gecko 17?

The real problem was using an old 17.0 Gecko SDK. With SDK 17.0b6 there is no problem.
Thx for fast help, Kyle!

How does bug 813264 affect this?

As Neil alludes to, this is actually our fault for changing the interfaces
during beta. We've undone that now. The released version of Firefox will
be shipping with the IIDs from 17.0b5 (and previous betas), not 17.0b6.
There are details in Bug 813264 if you're curious.
