We now check if the row exists in the current view, and only then do we
process the submessages in it, instead of letting `Error: Failed to
do_process_submessages` happen.
In 61b3c698af we stopped restoring widgets
from the cache, so the only purpose of the cache remaining was to access
the event handler patched onto the widget jquery.
Now instead of the entire jquery object, we cache just the event handler
since that's the only thing we need from the cache, and do not patch it
onto the widget jquery object.
Earlier we did not activate widgets if their rendered HTML was cached,
and also when narrowing to the combined feed view. This caused bugs with
widgets not being activated, and so not responding to any interactions.
Now we unconditionally render and activate widgets in the current view,
irrespective of the cached HTML or the view being narrowed to.
Uptil now, users could add tasks to a todo widget only after creating
it through the `/todo` command in the compose box.
Users can now add an initial list of tasks using the `/todo` command,
with each task on a new line in the compose box, where the 1st `:`
would separate a task from its (optional) description. Example:
`/todo\nTask1:description1\nTask2 without description`.
Fixes part of #20213.
Users can now name task lists by providing the task list title in the
`/todo` command on the same line. Example: `/todo School Work`. If no
title is provided by the user, "Task list" (which is also the
placeholder) is used as default.
The author of a task list can later edit / update the task list title
in the todo widget, just like the question in the poll widget.
Fixes part of #20213.
The schema now ensures extra data is validated according to the widget
type. This also makes it easier to modify the extra data for any widget
or add new widget types in the future.
