The default XHR error handler produce an alert which is appropriate to the response status code. It can be overridden per-request (by specifying the `errorHandler` option) so that the alert can be suppressed or displayed in a different position (e.g. inside a modal).
ref #118
Welp, this is probably the most subtle bug I've ever tracked down and fixed.
Turns out that IE has this bug where the "oninput" event will be triggered whenever the "placeholder" attribute is changed. Most placeholders get their value from app.trans. The app.trans method returns a VirtualElement – which is an array, not a string! That means when Mithril's diffing algorithm was comparing the old value to the new value, it was comparing two different array instances, and thus deciding the value was dirty and the placeholder attribute needed to be updated. Due to the IE bug, that was leading to the "oninput" event being triggered... and then through Mithril's auto-redraw mechanism, a redraw would be triggered, and so the cycle continued.
Since the inputs in the LogInModal (among others) only update the component state on the "onchange" event (i.e. when the input loses focus), the intermittent redraws would cause the input's value to be cleared continuously. That's what was causing #464. Could've been easily and superficially patched by changing them to use "oninput" events, but luckily I dived a little deeper!
Glad that's over. Running IE11's buggy dev tools in an underpowered VM isn't fun. Would not recommend.
closes#464
Improved consistency for existing core translation key names.
See flarum/core#265
- Completely overhauled core en.yml
- Replaced existing key names in all core JS files to match
- Extracted a hardcoded string in IndexPage.js
- Combined two app.trans calls in DiscussionControls.js
- Removed hardcoded spaces from LogInModal.js and SignUpModal.js
- Added two new keys from DiscussionControls.js (soft delete)
- Created two new “reused keys” to YML to accommodate same
