Re: [xwiki-users] [xwiki-devs] Questions about Blog Example

Hi, Anca, Thanks very much for your response, I understand how data are saved to database now, but I got another question: In the following code from BlogPostSheet <dl> <dt>$msg.get('xe.blog.sheet.**title')</dt> <dd>$doc.display('title', 'edit', $entryObj)</dd> <dt>$msg.get('xe.blog.sheet.**content')</dt> <dd>$doc.display('content', 'edit', $entryObj)</dd> <dt>Feature ID:</dt> <dd>$doc.display('FID', 'view', $entryObj)</dd> <dt>Package ID:</dt> <dd>$doc.display('PID', 'view', $entryObj)</dd> <div class="clearfloats"></div> </dd> </dl> If I change the 'view' to 'edit' for both FID and PID, then both of FID and PID will be saved to database, and I can query retrieve them, but I have use view, then they are not saved to database. the problem is I donot want these two fields editable, so I have to use view, any workaround for this? so the bottom line is I want them to be saved to database and not editable from the inline form.
