Querying (SOQL) CaseFeed returns incomplete information for some types (for example TrackedChange and EmailMessageEvent).
Both of these StackExchange searches return zero results:
- casefeed soql EmailMessageEvent
- casefeed soql TrackedChange
Most of the information on this topic (casefeed soql) seems dated and/or does not work. Other information is pointless like using a Feeds sub-query in a Case query. It returns the same results as a CaseFeed query.
I've seen examples of sub-queries using FeedTrackedChange, but they fail. The API Describe for FeedTrackedChange says it's not queryable.
The Chatter/Connect API is completely useless for a system app because of its licensing model.
Has anyone made progress getting the details/content associated with TrackedChange and EmailMessageEvent?
Added information
It's possible that some of my failed queries were due to the query tool (Workbench) rather than the SOQL itself. I started to make progress when I moved over to VS Code's SOQL Builder.
With respect to the FeedTrackedChanges item... I was going to post a more complete example, but the following query is working well in VS Code: (not in Workbench)
SELECT Body, CommentCount, CreatedBy.Name, CreatedDate, LinkUrl, Id, IsRichText, ParentId, Title, Type, Visibility, (select FieldName,OldValue,NewValue from FeedTrackedChanges)FROM CaseFeedWHERE ParentId = 'case Id here'Note: This query just spins the progress wheel in Workbench.
I made no progress on EmailMessageEvent, but I know how to query the EmailMessage object. So my current strategy is to ignore CaseFeed.Type=EmailMessageEvent, and merge the EmailMessage objects into my collection of feed items. I don't like to reinvent things that already exist though. I'm a little concerned that I might be repeating work already done by Salesforce.
