Symptoms
When trying to edit an attachment (Excel, Word doc, etc) they are open in read-only mode. When editing the attachment Confluence logs the following stack trace:
1
2
3
4
5
Caused by: java.lang.NullPointerException
at com.atlassian.confluence.pages.DefaultAttachmentManager.saveAttachment(DefaultAttachmentManager.java:78)
at com.atlassian.confluence.extra.checkout.VersionedAttachmentManager.saveAttachment(VersionedAttachmentManager.java:45) <--- this is an entry from the Attachment Checkout plugin
at com.atlassian.confluence.pages.DelegatorAttachmentManager.saveAttachment(DelegatorAttachmentManager.java:83)
at sun.reflect.GeneratedMethodAccessor2675.invoke(Unknown Source)
Cause
Using the above stack trace as an example, the Attachment Checkout plugin by Locus-Global was responsible for interfering with the Office Connector operation. Specifically the version of the Attachment Checkout plugin used was an old version.
Resolution
If you encounter read only when editing a document attachment, check your atlassian-confluence.log file to see if there's an error logged. From the stack trace we may be able to learn more about the error. If the stack trace is related to another plugin like in the above, try to upgrade that plugin and check if that fixes the problem.
