3. Save Jira issues macro for confluence page

Expected Results

Actual Results

In view mode of the Confluence page the Jira issue macro show epic name column with an encoding problem:

Notes

When analysing the browser developers tool content, we notice that the both the response and preview from /rest/jiraanywhere/1.0/jira/clientIds call has the data correctly encoded:

• Response:

  \\u003ca href\\u003d\\\"http://quicksilver/jira/browse/GHS-30?src\\u003dconfmacro\\\"\\u003e\\n                                            solicitações de usuários\\n                                        \\u003c/a\\u003e\\n
  

• Preview from /rest/jiraanywhere/1.0/jira/clientIds:

  class="icon" /></a>↵                                                    …src=confmacro">↵                                            solicitações de usuários↵                                        </a>
  

Which means that only the rendering process of JIM is breaking the encoding.

Workaround

1. Sort table by clicking on any column name (obs.: /rest/jiraanywhere/1.0/jira/renderTable is called)
2. Reduce columns to display to key, summary and epic name

Both workarounds result in the correct rendering of the special characters:
