Calling sidebar two times, widgets have the same ID

[alexvorn2]

If we call in the Twenty Thirteen the function of the sidebar

<?php dynamic_sidebar( 'sidebar-2' ); ?>
<?php dynamic_sidebar( 'sidebar-2' ); ?>

then the widgets ids from each sidebars are the same.

[alexvorn2]

this is not valid to have the same id two or more times

Why would someone call a sidebar twice on a page?

[alexvorn2]

for example you want to show the same widget area in the header and in the footer, a widget that shows recent posts.

Thanks for the report alexvorn2. Sorry you never got a response for so long.

While you're certainly correct that the ID shouldn't be reused, the use-case of someone calling the same widget-area twice is exceptionally rare (and possibly not permissible for acceptance into the wporg theme repository). I suggest this as wontfix since the proper (and expected) use would be to not reuse a widget area on the same page. I could see footer1 (show only on pages) and footer2 (show only on posts) but plugins like widget visibility seem more appropriate for that.

Basically this error would be as expected, you're calling the same sidebar twice.

Agreed, themes should always use multiple sidebars for multiple widget areas. It should be the user's decision if they want to show the same widget in more than on location.
