Step to reproduce:

1. Create a table with 30 row.
2. Fill all the table row with some word
3. Highlight one of the row and click the JIRA issue icon
4. Select the option Create X issues from this table
5. Then select create.

Expected result
New JIRA issue will be created in JIRA project and the link will be added in the Confluence page.

Observed result
New JIRA issues are created in JIRA project however no link are added in the Confleunce page. Sometimes the process will hang and you are force to refresh the page. An error is displayed:

X issues have been created, but there are problems in adding them to the page.
You can manually add them later using JIRA macro.

(Jul-19-2018) - A recently observed result in Cloud application: Instead of displaying the message above, it only refreshes the page and the content is not created in Confluence. Only in Jira.

The following will appear in the logs as well:

(May-29-2019) - The JIRA Issue link is added when using the old editor. This seems to be affecting only the new Confluence editor.

Workaround

The only available workaround is to manually add JIRA issue links to the page.

OR

Use the old editor
