This is partly a fix to #7574, although quite different from the work Ingo did on Content-length. The text/json mime type occasionally gets a charset suffixed to it by the webserver, which broke everything.
A follow-on fix from this would be to get the PHP code to supply charsets more consistently, so that webservers don't have to make things up.
Additionally, the 2nd interpretation - which treats the response as text/html - should probably only happen if the response is text/html, and throw a more helpful error otherwise.
Avoid ajax reloads when URLs differ in irrelevant ways,
e.g. admin/?locale=de vs. admin?locale=de.
This caused problems with the translatable module
reloading page content where it didn't need to,
because some previous robustness patches to the same problem
didn't apply (they only removed trailing slashes, ignoring
query parameter strings). The visible problem for this was
a broken tree panel, because it was ajax-loaded in parallel
with its container. Depending on ajax response order,
this would break the inner panel (in this case the tree),
since its original container was replaced with a new DOM.
Guess the fragment based on the returned HTML.
The validation error HTTP response is generated by Form rather than
the controller (LeftAndMain), so we can't set custom PJAX headers easily.
Implemented independently of URL state to ensure that
state is retained on every user interaction, rather than
having to add it to each URL specifically.
Same reasons for not saving it as HTML5 history metadata,
as that's only inspected on history events, not
normal CMS navigation.
When one or more fragments are requested that are not in
the current DOM, we need to force loading the outermost
fragment instead (currently hardcoded to "Content").
This mainly prevents history back navigation from breaking,
e.g. admin/pages -> admin/pages/list ->
admin/pages/list/?ParentID=99 -> admin/pages/edit/show/5 -> (back)
Was using text/json, which Form->httpSubmission() interprets
(correctly) to returning JSON validation data.
This trips up the interface, which expects HTML with
the validation errors directly in the markup.
Broke when CMS URL already had query params,
such as ?locale=en_US with the Translatable module enabled.
With this patch it doesn't double-concat ?locale....
Still doubles query params, but that's acceptable
until we find a more solid URL manipulation lib for JS.
- Changed application order
- Fixed layout trigger after preview toggle
- Replaced button row dimension approximation with double application of jQuery.layout() - once before sizing the action panel height to set correct width on container, then again for the height
There is no way to clean up attached Chosen instance in a nice way -
there is no destroy, nor remove on the library.
Also, we can't use the onunmatch on this entwine - it only triggers after the cache snapshot
has been taken. This is because the cache function is on different
namespace.
