Cannot cancel the check-out of documents in Case Client that were added from an Alfresco CMIS repository
You can add
documents from an Alfresco CMIS repository as case
documents or as attachments.
However, if the case folder contains external documents, the Cancel check out action is disabled for the documents from the Alfresco CMIS repository after you perform a Checkout action. Thus, you cannot cancel the check-out of the documents in Case Client.
To work around this issue, browse to the documents in the Alfresco CMIS repository and cancel the check-out.
