Same issue for weblinks: needs a separate PR in the weblinks project.
I did not do menu items in this patch as it looks we may have to check for other aspects in the code.

Thanks JM. Could you please change the the line of code from:

 $origTable->load((int) $input->getInt('id'));

To:

$origTable->load($input->getInt('id'));

We call $input->getInt('id'), so the data is sanitized to integer already and no need for (int) before.

Please help making the change in the article model as well.

From my quick review, It looks OK. I will test it with the mentioned components when I get home later today.

Done as well as ither code style issues.
Corrected article directly with another cs too
