* egw.jsonq() now always returns a promise like egw.request(), still supporting old callback syntax
* egw.link_title(_app, _id, _callback, _context, _force_reload) supports boolean values for _callback (to not break existing code)
- false: just a cache lookup (like current call with just 2 parameters), returning null, if no title is cached, or the title
- true: always return a promise, which might already be resolved, if title was cached
- function: also returns a promise and calls the callback
--> calling egw.link_title(_app, _id) without 3rd parameter is deprecated now (gives a console.trace), to be changed in future to always return a promise, unless called with false, to just return a cache-lookup
* Et2SelectAccountReadonly and et2_link_widget is changed to use the new/updated syntax with promises
- Remove margin from input,button,select
- Fix some spacing issues
- Switch selects from display:inline-block to display:block so they take up all parent's space
- Let background (required) color show through select tag
- Some layout tweaks on mail account template
- Dates have their input as slotted, not internal
- Selects have .select_options, not .get_select_options()
- Remove this.egw().lang() use from Et2InvokerMixin._invokerTemplate()
- get_select_options seems to be nowhere in use, so I did not implement it
- Et2Select* widgets with static options assign them in their constructor (like the r/o ones)
- removed a jQuery.proxy call, which we dont want in new code
Had to overwrite some formMixin methods, which considered everything not string as invalid and set/get value to do the right thing for multi-select
Not sure if code should go to Et2WidgetWithSelectMixing to be shared with TagList ...
Any child that has selectbox type functionality (extends Et2WidgetWithSelectMixin) needs to implement:
- _optionTargetNode() : HTMLElement
- _optionTemplate(option : SelectOption) : TemplateResult
@Nathan: Not sure if this is the right fix, but I can't see where we use Lit's FormatMixing, which defines serializedValue (and therefore select-box always returns the old modalValue)
Paying more attention to the WebComponent life cycle here, rather than what our widgets do - connectedCallback(), requestUpdate(), updated() are more important than loadFromXML(), etc. which are only used when loading from the .xet the first time.
