Symptoms

Out of Box attachment url ("Link to item") for a custom SharePoint 2013 List is displaying repeated relative URL of the subsite.

 

Diagnoses

The following steps were taken to reproduce the issue.

- Create a subsite on a wildcard site collection. I used portal - https://portal.denallix.com/ - it will be https://portal.denallix.com/sites/sYourSiteCollection]/]YourSubSite]
- Create a SharePoint 2013 List
- Click on K2 Application from the list ribbon to generate SmartObjects and Forms.
- Add a workflow (K2 for SharePoint workflow, not K2 studio workflow). Start manually option is selected.
- The workflow has one SmartForms client event that assign task to the originator. Set Form to "display form" on "specify the form for this User Task".
- Add list item (with an attachment).
- Start the workflow manually by clicking on "K2 Workflows" for the list item added.
- Open the task assigned to the user by selecting Open form from worklist item.
- When the form opens scroll down to the Attachments section, hover-over an attachment, at this stage you should see a repeated /sites/sYourSiteCollection]/sites/s/YourSiteCollection]].

The workflow is not really an important part, you can simply run "Get Attachments" method of your list attachments SmartObject. You will notice that 'Link to Item' URL is incorrect.
