We're trying to validate a Droptree field to only allow a certain template type be selected. We've found the /sitecore/system/Settings/Validation Rules/Field Rules/System/Linked Item Has Allowed Template; the only field rule validator that is within Sitecore.Marketing.Taxonomy, all others are within Sitecore.Kernel:

Sitecore.Marketing.Taxonomy.Validators.LinkItemTemplateValidator,Sitecore.Marketing.Taxonomy

We've created a new validator that references the Type above and set the Parameters to several variations of the following with no luck:

  • IncludeTemplatesForSelection={5A0F5DE2-8209-438E-A281-F8E8479B9565}
  • IncludeTemplatesForSelection="{5A0F5DE2-8209-438E-A281-F8E8479B9565}"
  • IncludeTemplatesForSelection="Event"
  • IncludeTemplatesForSelection="/sitecore/templates/Event"

Has anyone had success with this validator? Any help would be much appreciated, thanks!

  • Try IncludeTemplatesForSelection="Template Name" – Siva Kumar Nov 22 '18 at 12:50

“Linked Item Has Allowed Template” Field Validator is working as expected for Droptree field. You need to add DataSource=/sitecore/content/Home&IncludeTemplatesForSelection=Template Name in Source field.

Note: IncludeTemplatesForSelection should be equal to Template Name without double quotes.

  • This appears to be an invalid entry in the Source field: The item "Related Event" contains broken links in these fields: Source IncludeTemplatesForSelection=Event – HCFLGov Nov 28 '18 at 21:31
  • However, it does seem to work. Is there a way to include the IncludeTemplatesForSelection parameter with a starting point in the content tree? For example:/sitecore/content/Home/Calendar – HCFLGov Nov 28 '18 at 21:39
  • This looks like it might do the trick: DataSource=/sitecore/content/Home/Calendar&IncludeTemplatesForSelection=Event. Thanks for your help! – HCFLGov Nov 28 '18 at 21:48
  • Thank you. I missed adding Datasource. I'll edit the comment. – Siva Kumar Nov 29 '18 at 4:34
