Invalid DateTime

May 7, 2012 at 10:35 PM

I've installed BE version 2.6 RC and after logged in, I opened the Dashboard and get this error:

Row 127:
Row 128:@helper GetLatestPackages(){
Row 129:    var packages = PackageRepository.FromGallery("all", 0, Gallery.OrderType.Newest);
Row 130:    
Row 131:    if(packages != null && packages.Count() > 0){

Source File: c:\inetpub\wwwroot\webaspx\blogengine-rc\App_Code\Helpers\DashboardHelper.cshtml    Row: 129

Is there something wrong with my configuration?

Thanks in advance, have a nice day! :-)

Well, in the page DashboardHelper.cshtml on row 129, if I change the value Gallery.OrderType. from Newest to any other value, like Alphanumeric, Downloads or Rating, it works!

Same problem.

Does list in the Dashboard works for you guys? It also sorted on date, but probably uses different sorting code. If it works, I could look and change it to use same code as dashboard. Problem here is that I can't reproduce it locally because it is probably combination of your server locale plus client machine/browser locals and settings that causes issue, so I would need help verifying it works. For me it is fine even if I switch language in admin/settings or my browser.

 Hi rtur.
My cultureinfo is es-ES.
The method that throws the error is FromGallery (PackageRepository class). Convert.ToDateTime not know interpret the date correctly:

case Gallery.OrderType.Newest:
	packages = packages.OrderByDescending(p => Convert.ToDateTime(p.LastUpdated, culture)).ThenBy(p => p.Title).ToList();

I think the problem is in the Utils.GetDefaultCulture() method.

My solution was change to culture InvariantCulture: 

        public static CultureInfo GetDefaultCulture()
            var settingsCulture = BlogSettings.Instance.Culture;
            if (Utils.StringIsNullOrWhitespace(settingsCulture) ||
                settingsCulture.Equals("Auto", StringComparison.OrdinalIgnoreCase))
                return CultureInfo.InvariantCulture;

            return CultureInfo.CreateSpecificCulture(settingsCulture);

Regards and thanks!

It's strange... I have installed BE on another local host machine, and it doesn't seems to be any error!!

Do you think that the solution proposed by @GabrielGI could be useful to prevent this error?

Thanks, and have a nice day! :)

I made a change for gallery sorting to use invariant culture regardless, this should work for all cases. It is in for 2.6 final release.
