Banner image for child domain does not display when logged into child domain

When adding a company image to a child domain record while in a parent domain, the image will not show while viewing form in said parent domain. This is because the banner image attachment takes the session domain of the user who added it instead of the domain of the company record.

 

1. Activate the Domain Support - Domain Extensions Installer plugin.
2. Create the following domains:
   
   1. TOP => LEVEL1
   2. TOP => LEVEL1 => LEVEL2
   3. TOP => LEVEL1 => LEVEL2 => LEVEL3
3. Create a company in the LEVEL3 domain.
   • Note: It may be necessary to add the Domain field to the core_company form.
4. In the core_company record for the company just created, add a banner image.
   • It may be necessary to add the Banner Image field to the core_company form.
5. Navigate to the sys_attachments table and find the record that was just added.
   • Rearrange the sequence by Created (descending), and look for a record with file name of banner_image and table name of ZZ_YYcore_company.

Expected result:

The domain of sys_attachment record will match the domain of the core_company record.

Actual result:

The domain of the sys_attachment record matches the domain that the currently logged in user had selected at the time (in this case, it should be global).
