That was becuase not enough information was being passed in for the blocks editing controls to construct the right URL to reload the page.
It is also now possible for admin external pages to add some UI next to the turn blocks editing on/off button. For example, when you are editing the list of course catgories, the turn editing off button is now in the right place.
Also MDL-17585 Improve layout of manual grading forms to make them look more like formslib forms. The standard trick of stealing the HTML and class names that formslib works, so the standard style rules apply to your form.
1/ email notification when course requested
2/ course request capability so that we can limit who can request new course
3/ list of my pending course requests on the request form
Implemented in 1.9 by Petr Skoda, and reviewed and merged to HEAD by me.
* Note: this would never lead to problems with default role definions.
* Also ended up mostly rewriting delete_category_form to simplify the messages that are displayed.
* New helper function require_all_capabilities, a bit like require_any_capability.
1. If a user does not have that capability, don't let them change whether the course is visible.
2. Give teachers that capability by default.
3. To avoid regressions, on upgrade, give moodle/course:visibility to any role that has moodle/course:update.
Bugs: MDL-17479, MDL-16426, MDL-16063, MDL-16013, MDL-15658, MDL-15556, MDL-15161, MDL-14925, MDL-13742, MDL-11557.
* Simplify category editing permissions to just moodle/category:manage and moodle/category:seehiddencategories.
* Enforce those correctly. (Note MDL 17502 is still outstanding.)
* Don't screw up category sort order when you just edit name or description.
* Niceties like where redirects go when you cancel or submit forms.
* Make sure a global course creator can see the site admin block.
* Don't allow a category to be made the child of one of its children!
* General code cleanup to bring key files more in line with best pracitice.
Apologies for the fact it is one big patch, rather than a series of smaller patches. However, categoryedit.php, category.php and index.php where in pretty bad shape and needed significant cleaning up. categoryedit.php, in particular, was almost completely rewritten.
Merged from MOODLE_19_STABLE.
In the 1.9 branch this is controlled by a new option under Admin -> Experimental. In Moodle 2.0 dev it is not optional, it just works.
The main change is letting the manual grading report know which random questions might need manual grading. MDL-4004 - this depends on the random question under consideration, which requires a new questiontype method.
I also changed the random question code so that I could remove some global variables.
