Restriction of DisplayOptions tag not working

Hi,

I am using multiple display options on my website and am trying to set up a block so that it only uses one of the display options. I have got the following display options set:

    public class SungardDisplayOptionsProvider : IDisplayOptionsProvider
    {
        public const string FullWidthTag = "full";
        public const string OneHundredTag = "100";
        public const string SeventyTag = "70";

        public void InitializeOptions(EPiServer.Web.DisplayOptions options)
        {
            options
            .Add("full", "/displayoptions/full", FullWidthTag, string.Empty, "epi-icon__layout--full")
            .Add("onehundred", "/displayoptions/onehundred", OneHundredTag, string.Empty, "epi-icon__layout--full")
            .Add("seventy", "/displayoptions/seventy", SeventyTag, string.Empty, "epi-icon__layout--full")
            .Add("fifty", "/displayoptions/fifty", ContentAreaDisplayOptions.Fifty, string.Empty, "epi-icon__layout--one-third")
            .Add("thirty", "/displayoptions/thirty", ContentAreaDisplayOptions.Thirty, string.Empty, "epi-icon__layout--one-third")
            .Add("twentyfive", "/displayoptions/twentyfive", ContentAreaDisplayOptions.TwentyFive, string.Empty, "epi-icon__layout--quarter");

        }
    }

In my TemplateCoordinator I do the following:

        public void Register(TemplateModelCollection viewTemplateModelRegistrator)
        {

            viewTemplateModelRegistrator.Add(typeof(CaseStudyFullWidthTextBlock), new TemplateModel
            {
                Tags = new[] { SungardDisplayOptionsProvider.FullWidthTag },
                AvailableWithoutTag = false,
                Path = BlockPath("CaseStudyFullWidthText.cshtml"),
                
            });

However, when I look at the CMS, I can see the following:

"The block 'Full width text block' cannot be displayed as /displayoptions/onehundred

The block 'Full width text block' cannot be displayed as /displayoptions/thirty

The block 'Full width text block' cannot be displayed as /displayoptions/seventy

The block 'Full width text block' cannot be displayed as /displayoptions/fifty

The block 'Full width text block' when displayed as /displayoptions/full

The 'CaseStudyFullWidthTextBlock' can not be displayed using the 'Full' display option

The block 'Full width text block' cannot be displayed as /displayoptions/twentyfive"

As you can see, it looks like it's trying to display the display option with the "full" tag as requested, but for some reason it can't. Even more strangely, If I set AvailableWithoutTag to true, all the views get rendered correctly for the block, including "full". This leads me to think there is a bug in episerver (I'm using version 9), but maybe i'm missing something?

Thanks for any help,

Sam

It looks correct according to the SDK. I've not tested the code myself though.

Spontenous answer Episerver support usually gives is "try to upgrade to a later version".

In case you don't have time to upgrade to 11, at least try to upgrade to latest version within Episerver 9 (NuGet Package). Or copy your code into an Alloy Website running the latest version of Epi.

For comparison I generally compare my code with the examples in Alloy or as I just mentioned copy my code into Alloy.

I wouldn't upgrade just yet. i filed a bug with epi on the version 11 where it will add the first modeltype and 1 display option but omits the others. The above code looks right though. For some reason, worth a check, does it view exist in the right path? BlockPath("xxxx.cshtml"). does the view exist?

@Joshua - yes the view does exist in the right path, and it renders correctly in the preview when I set AvailableWithoutTag = true.

@Alf - I'll try the upgrade and that's a good idea about using Alloy to test this functionality to see if it works in the latest version.

I can say this issue was fixed in a bug i filed. I upgraded to the version it was fixed in and appears to be working now. It would only register the first model and ignore the additional display options/tags.
