Return to site homepage… Cause java.lang.NullPointerException: inputStream cannot be null at com.google.common.base.Preconditions.checkNotNull(Preconditions.java:204) Stack Trace:[hide] java.lang.NullPointerException: inputStream cannot be null at com.google.common.base.Preconditions.checkNotNull(Preconditions.java:204) at com.atlassian.confluence.pages.persistence.dao.AttachmentDataStream$InputStreamWrapper.<init>(AttachmentDataStream.java:43) at com.atlassian.confluence.pages.persistence.dao.filesystem.FileSystemAttachmentDataDao.rawBinaryWrapper(FileSystemAttachmentDataDao.java:155) at com.atlassian.confluence.pages.persistence.dao.filesystem.FileSystemAttachmentDataDao.saveDataForAttachment(FileSystemAttachmentDataDao.java:150) at {code} The attachment which is stored in the filesystem are not moved to the new location after the question is moved to the new space. The attachment still exist in the old location in the filesystem. Because the question in the new space is trying to refer to the attachment in the new location, it could not find the attachment which resulted in the ERROR. For example Before the question was moved to the new space, the attachment is stored in the following location in the filesystem: {panel} /home/jing/atlassian/atlassian-confluence-5.6.6/data/attachments/ver003/172/223/59473922/146/60/59310146/59441182 {panel} After it has been moved it is still in the same location: {panel} /home/jing/atlassian/atlassian-confluence-5.6.6/data/attachments/ver003/172/223/59473922/146/60/59310146/59441182 {panel} By right, the value {{/172/223/59473922}} in the path above should be difference as it is suppose to be reffering to new spaceid as explained here https://confluence.atlassian.com/display/DOC/Hierarchical+File+System+Attachment+Storage.
