Global tags not working for loops?

Hi!
I register some global tags like this; template.SetTag("Global:NiftyTag", "stuff");
which is working fine.

Now I tried to create a loop, like this:

            foreach (Group group in groups)
            {
                this.DebugMessage("Name: " + group.Name);

                Dynamicweb.Templatev2.Template loopTemplate = template.GetLoop("Global:ProductCategories");

                loopTemplate.SetTag("GroupName", group.Name);
                loopTemplate.SetTag("GroupSmallImage", group.SmallImage);

                loopTemplate.SetTag("GroupLink", "Default.aspx?ID=" + pageID + "&GroupID=" + group.ID);

                loopTemplate.CommitLoop();
            }

But this is not working. In the template file, I have the following code:

    
        <a href=""></a>
    

Which is producing the following output, indicating the loop is undefined:

    <!--@LoopOutput(Global:ProductCategories_0)-->


How can I get this working?

Try inserting the

<!--@DwTemplateTags-->

tag into you template to verify that your tags are actually available. In which context is you code executed (PageLoad, ContentModule...)?

Yup. My tags are available, except the loop tag. I define the loop tag and the other tags as Global:blaha.

I use the Dynamicweb.Notifications.Standard.Page.OnGlobalTags event to set this tags on every page load.

I paste my actual code below, with comments added:

    [Subscribe(Dynamicweb.Notifications.Standard.Page.OnGlobalTags)]
    public class CleenleepPageLoadedEventHandler : Dynamicweb.Extensibility.NotificationSubscriber
    {
        public override void OnNotify(string notification, Dynamicweb.Extensibility.NotificationArgs args)
        {
            Dynamicweb.Notifications.Standard.Page.PageviewNotificationArgs s = (Dynamicweb.Notifications.Standard.Page.PageviewNotificationArgs)args;

            // This will work and set a global tag:
            s.Template.SetTag("FantasticTag", "CoolContent");

            // Get a list of groups. (returns a couple of eCommerce groups)
            List<Group> groups = this.GetCategories();

            // This code won't work: (the tag is not defined when I try to use it in the template.)
            foreach (Group group in groups)
            {
                Dynamicweb.Templatev2.Template loopTemplate = template.GetLoop("Global:ProductCategories");
                loopTemplate.SetTag("GroupName", group.Name);
                loopTemplate.CommitLoop();
            }
        }
    }

I think Global could be a reserved word. Did you try a different prefix?

I have tried different naming. The Global prefix should be there according to docs.

Hi Jon.

Just to be sure:
Are you on the Notifications.Standard.Page.OnGlobalTags trying to add a loop?
Because that is not possible.

If you want a "Global" loop, try the same using the Notifications.Standard.Page.AfterOutput which works very differently in this regard.
