Service Portal building conversation widget: Function from "API Server Side scoped" class: GlideSPScriptable.getStream(String table, String sysId) does not work as expected

For a client I am trying to modify the "Ticket Conversation" widget to display Activity Stream for a custom table in a similar way as the Service Portal demo does for Incidents.

I have created a custom table with journal fields and made table "auditable" in sys_dictionary. In the form (client) for the custom table the Acivity stream works as expected and produces a log for all activities.

I would now like to present the activity stream in the new Service Portal. The OOB widget "Ticket Conversations" does this in a neat way for some of the posts in the activity stream, I would like to modify it to work for a custom table and also add the possibility to see Historic changes to fields (not in the widget today).


My problem is that it seems to work ok when I extend a task table and point the widget to a record from the extended table. The issue in this case is that for this custom table we do not extend Task table. Result is that I am not able to retrieve the Activity Stream in the widget.

My question is if there is any setting on table level you have to perform to retrieve the activity stream.

If not, I believe there is a issue with the $sp.getStream(String table, String sysId) function from the API (https://developer.servicenow.com/app.do#!/api_doc?v=helsinki&type=server&scoped=true&to=method_class...).

It seems this function does not return the Stream Object as expected.

I have understood that the issue is on row #55 in "Ticket Conversation" widget Server Script. The row is: data.stream = $sp.getStream(data.table, data.sys_id);

This function call (when run on a record in a table extending Task) return the following object Object[display_value,sys_id,short_description,number,entries,user_sys_id,user_full_name,user_login,label,table,journal_fields]

When run on a table NOT extending Task it return the following: Object[table, sys_id]

If anyone has encountered any problems or has anoher solution to present the Activity Stream in Service Portal in a nice way, please comment.

Steps to reproduce issue:

- Create custom table (u_test_table)

- Add a "Journal" column and a "Journal Input" field to table

- Confirm Table is marked as "Auditable" in sys_dictionary

- Confirm Table is marked as "Live Feed" = true

- Install Service Portal for Enterprise plugin

- Copy "Ticket Conversations" widget to "My Ticket Conversations"

- Add "My Ticket Conversation" to a new page

- Access the page https://my_instance.service-now.com/sp?id=new_page&sys_id=MY_TICKET_SYSID&table=u_test_table

Result: Conversations for ticket is not shown. I have made the same steps but instead creating a custom table extending "task" table. If I do this the conversation is shown.

On the latest Helsink patch I've managed to make it work on cmdb_ci_outage table with a custom field called u_comments.

Hi Diego,



In my instance, i am able to see the activity details for request but not for incidents. When i try to write a log to find length of journal field i got zero for incidents and 2 for requests.



But, in my incident table we have additional comments and worknotes field. How to resolve this issue?



Thanks and regards


Swamy
