Thumbnails are not displaying in the Primo Front End

Symptoms

- PNX records contain a link/thumbnail element that uses a custom or customized thumbnail template
- The thumbnail template contains an ampersand (&)
- The thumbnail template is not for Google
- Examining the HTML with a thumbnail that does not display shows the ampersand has been encoded as &
- Tracing the network calls shows a URL containing an encoded ampersand &
 

Defect Status

Fixed in Primo November 2015 release

Replication Steps

1. Search for a record that has a links/thumbnail with the customized template (e.g. $$Tcontentdm_thumb)
2. Note that:
- No thumbnail displays
- Tracing the network calls shows the URL call contiain &
- Inspecting the page source shows a call to pushThumbnailsData('<THUMBNAIL_URL with &amp;>','exlidThumbnail_0_0')
Update the template, replacing the ampersand with \u0026
Deploy the change and repeat the search
Note that:
The thumbnail displays
Tracing the network calls shows a call to http://{server}:81/cgi-bin/thumbnail.exe?CISOROOT=/astro_atlas&CISOPTR=1355
Inspecting the page source shows a call to pushThumbnailsData('http://{server}:81/cgi-bin/thumbnail.exe?CISOROOT=/astro_atlas\u0026CISOPTR=1355','exlidThumbnail_0_0')

Workaround

1. Go to the Primo Back Office - Advanced Configuration - All Mapping Tables - Sub-System: Delivery and edit the Templates Mapping Table
2. Find the row with a value in the Code column matching the $$T value (e.g. contentdm_thumb)
3. Update the value in the Template Code column
- Find the ampersand (&)
- Replace it with \u0026
4. Save the Templates Mapping Table
5. Deploy the Delivery Settings (GetIt and Availability)

Additional Information

For example, the Template contentdm_thumb is defined as

http://<server>/cgi-bin/thumbnail.exe?CISOROOT=/{{control/addsrcrecordid}}&CISOPTR={{control/originalsourceid}}

When examined in the HTML of the Primo Front End an example link with this problem would be:

http://<server>/cgi-bin/thumbnail.exe?CISOROOT=/astro_atlas&amp;CISOPTR=1355
