1. The new clear() method is called during refresh(), so the facet with
the old data is still shown for a brief moment before it's cleared.


The clear() should be called before show(). However, if the pkey/filter
is unchanged (check using needs_update()) we just need to show() the
facet, no need to clear() and refresh() again. The above logic needs to
be fixed.

Changed.

The we will need to override the needs_update() for search and
association facets because the default one always returns true.

Done

On the second thought, this might not be sufficient to detect the
changes in the list page. Try changing an attribute in an entry, then go
back to the list page, the list page will not show the updated attribute
because the filter is not changed.

I think we should remove the needs_update() from the search facet so it
will always refresh, but we probably can keep it for association facet.
What do you think? Sorry about that.

Changed to refresh always. Clearing always or not clearing at all seems wrong. When the pkey doesn't change, only small portion of values can/will change, so it's probably not so wrong to show the previous list, but when the filter is changed the results will be probably much different and the clear is needed. What do you think? -> Added needs_clear method which clears if the filter changes (basically renamed needs_update).

There are probably better solutions, but let's do this separately.

In future we can build a mechanism for subscribing to events from different facets and doing appropriate actions.

Something like:

var refresh_search_on_save = function(spec) {
    var that = {};

    that.register = function() {

        that.entity = IPA.get_entity(spec.entity);
that.details_facet = that.entity.get_facet(spec.facet || 'details'); that.search_facet = that.entity.get_facet(spec.search_facet || 'search');

        that.details_facet.on_save.attach(that.on_save, that);
    };

    that.on_save = function() {
        that.search_facet.set_needs_refresh(true);
    };

    return that;
};

So the facets won't be dependent on each other.

5) Added ID generator, using in radio_widget, same reason as #4.

The get_id() method (might be better called get_next_id() or
generate_id()) doesn't really need to take a widget parameter. The
id_count should be unique enough. If you want, it can take an optional
prefix so the ID will be like '<prefix>-<id>'. It will make it more
usable for other things not just widgets.

changed to get_next_id(prefix).


9. The facet header's clear() calls load() with empty data. The load()
will display the facet group label using facet's pkey. Since this is
called before refresh(), sometimes you'll see 'undefined' or the old
pkey. I think the code in entity.js:351-354 should check if the data is
empty it should clear the label.

Fixed

10. Instead of emptying button label in host.js:731-732, it's probably
better to reset it to its initial value:

var password_label = $('.button-label', that.set_password_button);
password_label.text(IPA.messages.objects.host.password_set_button);

Seems more proper to clean the label. If the label is set to ...host.password_set_button it will always shows before load "set OTP" after load it can change to "reset OTP" which is wrong behavior.
