I developed a plugin which shows related info from a custom application in a separate tab on the issue page. This can be done by embedding the external content in the issuetab or by showing a link in the issuetab which the user can click to display the info.
However, when the tab is displayed I get a 404 because the link which is to be shown resolves to a link prepended by the plugin URL. E.g. the link in the HTML source is:
but when clicking it the user is redirected to
How can I include links to external sites?
BTW: the link worked perfectly in our Jira/Server plugin.
Thanks in advance,
