The pending promise should nott be resolved until the changes are
complete.
Previously the resolution of the pendingPromise was triggering the other
changes.
This includes a minor restructure of the autocomplete JS to make use of
promises and improve tracking of pending JS.
In particular it improves the way in which throttled text input is
handled to ensure that the behat does not continue until:
- typing is fully complete; and
- all possible ajax requests have been sent; and
- all possible ajax requests complete; and
- the suggestions are updated.
A number of conditions existed where behat would move on to the next
step too early in a race condition effect between Behat and Autocomplete.
The form-autocomplete module uses three Mustache templates
core/form_autocomplete_input, core/form_autocomplete_suggestions and
core/form_autocomplete_selection. However, it did not support executing
the JS that is eventually part of those templates.
Custom AJAX handlers for the form autocomplete fields can now optionally
return string in their processResults() callback. If a string is
returned, it is displayed instead of the list of suggested items.
The string is displayed same way as we inform about no available
suggestions.
When using the AJAX autocomplete field, it allows JavaScript to add
custom HTML to selected options. For example, the user field from
the assign roles page includes an icon and other information by the
user's name.
Once you submit the form and the page reloads, there was no way to
provide this information back to the autocomplete field. HTML
<option> tag was used for the value names but it may only contain
text, not tags, so including it in the normal value did not work.
This change adds a new option for the autocomplete field that lets
you include HTML to override the default (text-only) value of the
label used to represent each option.
We want to avoid page jumps wherever possible. This change uses the original select element as a "proxy" to reserve the space
in the DOM for the enhanced auto-complete when the JS runs.
It uses visibility: hidden to make the select not rendered - but still take up space.
The exact sizing for the CSS was determined by testing and reverse engineering the bootstrap calculations.
The size of user pictures in selectors was reduced to avoid flicker when switching between no selection and a selected user. I
could have reserved a larger amount of space, but it looks worse for pickers with no pictures.
* We have duplicate input event handlers for the autocomplete element
which are both firing when the input element's value is being set.
In case an AJAX handler is defined for the autocomplete suggestions,
this causes the autocomplete suggestions so show "No suggestions" first
and then load the results from the AJAX handler a little bit later.
* New optional parameter 'closeSuggestionsOnSelect' for the enhance()
function for form-autocomplete. Setting this to true will close the
suggestions popup immediately after an option has been selected. If not
specified, it defaults to true for single-select elements and false
for multiple-select elements.

* Fix coalesce on postgres.
* The edit icon's alt shows the HTML entities causing
* enrol/tests/behat/add_to_group.feature Contains a '@doit' tag which I assume is there from testing.
* group/classes/output/user_groups_editable.php
** Missing MOODLE_INTERNAL check.
** Unused variables context_system and moodle_exception.
** The PHPDocs for the constructors are wrong.
** export_for_template() returns an array, not stdClass (according to parent docs).
** Change moodle_exception to coding_exception at the beginning.
* group/lib.php
** Missing docs for core_group_inplace_editable().
* user/classes/participants_table.php
** The docs for the class variables $groups, $course and $context need a '\' beforehand as they are in a namespace.
** I would prefer $this->context = $context; and $this->groups = ... to be done at the end of the constructor with the other class variable assignments.
** You could get rid of the class variable courseid if we are setting course and use $this->course->id instead.
** The function col_groups has @param \stdclass $row but it should be $data
* lib/amd/src/form-autocomplete.js and lib/amd/src/inplace_editable.js
** Some issues here CiBot has pointed out.
* lib/classes/output/inplace_editable.php
** @see should be on a new line.
Allows adding multiple instances of the meta enrol plugin at once.
I had to add support to the autocomplete element for filling the field from behat
when it was not using tags. I also had to make the shortnames more easily searchable
and unique in the behat feature file.
Incorrect types were preventing the currently selected values from
being removed from the new values returned via ajax.
Also fix a selection bug with autocomplete+ajax+singleselect.
This is a squashed commit containing a number of changes:
This is an ajax driven course selector that has searching etc. It can select single, or multiple courses.
Make course selector accept a list of courses to exclude
courseselector - lookup coursename on setValue
Use the get_course_display_name_in_list function to generate the course names
Add a throttle to auto-complete to reduce spamming the server
Do a single query to fetch all the courses in the mform element when validation fails
Fix core course search function to return results when there are less than 2 chars in the query.
Handle setData with an empty array in new course selector
Quickly navigating via the keyboard to an autocomplete
element and hitting down would result in the selections
being displayed and then quickly removed. This has now
been fixed.
