I have defined a custom issue relation. And I have two workflows for two different issue types. In one of the transitions of workflow 1 an new issue for workflow 2 gets created and my custom relation gets used to link the two issues. The new issue of workflow 2 relies on issue attributes of the workflow 1 issue. Workflow 2 will break, if someone removes the link.
Because of this, I would like to make the issue link read only. How can I protect the issue link?
