Hi Yury,
very nice input, I love it.

You are right, 1) should not be used anymore.
2) and 3) are actually both part of the new mechanism. The comment
about methods not being used yet are actually wrong, I really should
remove them. Generally you should not overwrite the get-methods.
Instead, to register resource loader modules and JS functions you just
use the add methods. The idea behind providing these add-methods is to
make it easier to build up the required datastructure so you do not
have to care about it. Long story short: Leave the getters alone, call
the adders.

We have to carefully distinguish between input id and input name here.
When the constructor of SFFormInput is called, you get as parameters
an input number and an input name.
For a simple HTML input element the number of the input should end up
in the 'id' attribute in the format 'input_<number>'.
The name of the input should end up in the 'name' attribute of your
HTML input element. This name is also what is sent back to the server
and finally used by SF to build the page text.

Maybe in addition to what Yaron said: If you are really intent to hide
the input until it looks nice you could try the approach from
HeaderTabs:
$parser->getOutput()->addHeadItem( HTML::inlineScript(
'document.styleSheets[0].insertRule?document.styleSheets[0].insertRule(".unselected
{display:none;}", 0):document.styleSheets[0].addRule(".unselected",
"display:none");' ), true );
This is approaching blunt force, though, so you should think carefully
if you really want to do that.

I would love to have this input in SFI!
Generally I try for compatibility with MW 1.17 and SMW 1.5.6, maybe,
although having not much contact with SMW from inputs I usually do not
test excessively against that requirement. As for SF, I try to keep
SFI in sync with the current version.
Cheers,
Stephan
