             Summary: error when remove page with link
                 Key: JSPWIKI-936
                 URL: https://issues.apache.org/jira/browse/JSPWIKI-936
             Project: JSPWiki
          Issue Type: Bug
          Components: Core & storage
    Affects Versions: 2.10.2
         Environment: Windows 8.1, Java 8u45
            Reporter: Andrew Krasnoff


# Login
# Create new page
# Then click Attach, select file and click Upload
# Edit the page and specify link to attached file name on page content -	[attached_file_name.png] in my case. Click Save
Click Info and click "Delete Entire Page", click "Confirm" at confirmation popup
=> get error

To make a temporary fix I updated "WikiEngine.deletePage" method with the following code:

{code:java}
    public void deletePage( String pageName )
        throws ProviderException
    {
        WikiPage p = getPage( pageName );

        if( p != null )
        {
            if( p instanceof Attachment )
            {
                m_attachmentManager.deleteAttachment( (Attachment) p );
            }
            else
            {
                Collection<String> refTo = m_referenceManager.findRefersTo(pageName);

                if (m_attachmentManager.hasAttachments( p ))
                {
                    Collection attachments = m_attachmentManager.listAttachments( p );
                    for( Iterator atti = attachments.iterator(); atti.hasNext(); )
                    {
                        Attachment attachment = (Attachment)atti.next();
                        refTo.remove(attachment.getName());

                        m_attachmentManager.deleteAttachment( attachment );
                    }
                }
                m_pageManager.deletePage( p );
                firePageEvent( WikiPageEvent.PAGE_DELETED, pageName );
            }
        }
    }
{code}
