CB

CBIF's also have issues.

Fixed in commit 93b6fd292421cd140f132abf598a5606172e8fc3

In new MR !1039

Could reproduce the bug reported here:
https://www.joomlapolis.com/forum/198-cb/233141-community-builder-2013-a-php-7-a-j-35-rc-2#279208

Argument 1 passed to CBLib\Session\SessionState::__construct() must implement interface CBLib\Session\SessionInterface, null given

The real error message got suppressed in CBSubs error handler, and the consequence was that Session could not be built. That is because PHP7 is more strict about reference parameters of a function being given a non-reference parameter.

And the distinction was not been made in the DI Container builder between a reference default value: basically for Session::_construct(&params = null) the default value null got given instead of a reference to a null value....

Fixed in commit 93aa15057b3a7b66d972917351c9991c1935aaed for MR !1039

These things too are generating notices:
call_user_func( array( $this, $methodName ), $name, $value, $param, $control_name );

with the thing called being:

function _form_list( $name, $value, &$node, $control_name, $ignoreClass = false ) {

Generates
Warning: Parameter 3 to CBLib\AhaWow\View\RegistryEditView::_form_list() expected to be a reference, value given in libraries/CBLib/CBLib/AhaWow/View/RegistryEditView.php on line 3360
