reload() doesn't resolve templates

[ribizli]

I've have a scenario to reload state if the user changes language. The language is changed on server side, so the templates are translated by the server (using a lang parameter or a session value for the language).

I've created a languageTemplateProvider function (used in state.templateProvider) like this:

function($http, $templateCache, languageService) {
    var langUrl = url + '?lang=' + languageService.selectedLanguage;
    return $http.get(langUrl, { cache: $templateCache })
        .then(function(response) { return response.data; });
}

On language change I clear the $templateCache so the template is re-downloaded from the server correctly.

But here comes the possible BUG: the state reloads/resolves before the $http finishes with the old template. Why?

On normal state change, the change happens only after the templates are correctly downloaded, so it seems correct (simulated with $timeout).

Sorry that I cannot provide a plunkr, but my app is already very complex to extract the needed components...

I'm wondering... I don't think we reload templates for any states. Once its loaded its loaded and unexpected to change. So I don't think we'd reload templates for reload() either.

There is a bug where controllers don't get re-instantiated, and that is a problem we are fixing, but not sure about templates. Maybe this is more of a feature request.

I see, but anyhow the templates are still re-downloaded, as I can see in network tab. Can you please check/confirm this?

Here the state a has language support, the template download is delayed with 2 seconds. State b is only a helper to load state a again when switching back to it. The language <li>s are clickable, I didn't bother with styling. State reload is called also on click. You can see in network tab the extra template load, which is unnecessary if template reloading not supported.

Ok so the problem is that the first template loads fine (delay and all) but the second template (when clicking 'de') loads in the network tab but never replaces the 'en' template on the page. Correct?

[ribizli]

Correct. Either no need to download, or the template should be replaced (but this might be a feature request as you mentioned).

[timkindberg]

Actually I think this is a valid bug. The template should be replacing the previous one. Thank you for finding this.

@timkindberg,

Is there an issue/commit for this? I just ran into this and don't know what the state of it is other than your comment.

[timkindberg]

yep. #582.

Closing because this is really really old, the plunker link doesn't work, and I think this is fixed in 1.0 codebase. Please reopen if the issue is still valid.
