Cannot Remove or Edit Properties of an Attachment with Umlaut Characters
Attachment contains an umlaut or other special character, e.g.
Attachment deletion fails with "Not Permitted" page even though user has sufficient permission:
Not Permitted You are not permitted to perform this operation.
Viewing or editing the properties of the attachment leads to a System Error page with the following stacktrace:
java.lang.NullPointerException at com.atlassian.confluence.pages.actions.MoveAttachmentAction.bootstrap(MoveAttachmentAction.java:112)
- The application server URL encoding is not set to UTF-8.
The URL encoding attribute is written wrongly or is incorrectly cased, hence Tomcat doesn't understand and pick it up. For example: URIencoding is wrong because it should have an uppercase E, and URlEncoding is wrong because it has a lowercase L instead of an uppercase I. The correct attribute is URIEncoding. It should look like this:
- Set your application server URL encoding to UTF-8 as described here. For example, in Tomcat add
URIEncoding="UTF-8"to the HTTP connector.
- Restart Confluence.
You might need to apply this to all available connectors, too (e.g. AJP connector).
