In our previous version, we had configured valid link schemes and associated these to projects.
Since the update, linking issues is not possible anymore.
When selecting an issue that can be linked (Story, there is a link to Card defined with type "consists out of") and clicking the button "consists out of Card", the special Minyaa dialog shows up.
This dialog contains an error stating:

Errors

• The issue type of issue [null] is not defined as a valid target in the associated Issue link Scheme.

When ignoring this error and choosing a valid issue to link, an error occurs. Following line shows up in the log file:

2011-01-26 16:11:23,078 ajp-8009-7 ERROR weynde 971x6138x1 1orcyj9 10.18.15.121 /secure/CreateLinkedIssue.jspa [web.action.issue.CreateLinkedIssue] Link to Original Issue failed due to invalid Original Issue Id.

How can this issue be resolved?
Kind regards,
Tom Moors
