Final answer:
If Dave only sees the profile and not the custom object in the User Story selections grid, the issue could be due to an incorrect deployment sequence, metadata filtering, or missing references in the profile. Dave should check the user story and repository to ensure all components are committed and referenced correctly.
Step-by-step explanation:
When Dave commits a profile and a custom object on a user story but only sees the profile in the User Story selections grid, there may be several reasons for the oversight of the custom object. In Salesforce development, which is contextually hinted by 'profile' and 'custom object', such a situation can occur due to factors like deployment sequence, metadata filtering, or profile-object dependencies.
The custom object might not be visible if it's not properly referenced within the profile's permissions or if any deployment step, that adds the custom object to the user story, was missed. Another possibility is that metadata components like custom objects might be filtered out in the view Dave is using. To troubleshoot, Dave should verify the user story setup, check the repository for the committed custom object, and ensure that all related metadata is accounted for in the deployment package.
