Issues with workbench moderation I've installed workbench and tried to work with it. I followed the step-by-step instructions given in the video here and I was almost successful in creating the content and moderating it between the two kinds of user one is Publisher and the other is content-creator. 

Content-creator creates the content and forwards it to needs-review, now the publishers gets the access to the content in the needs-review tab. And the moderation should be done between these two users.

Here, my issue is when the content-creator creates a content - he is unable to see his content in his profile (I mean either in 'MyContent', 'MyDrafts' and 'Needs review'). And the same case with the other user (publisher)- the Needs-review tab looks empty even though there is some content created by 'content-creator'.

To keep it short, MyWorkbench tab looks empty- the Needs-review tab, MyContent tab and MyDrafts tab are empty. The only way the content appears is in Content tab. 

I'm not aware of workbench module, I've followed all the instructions given in the video. I'm missing any?? Please give your answers. 

Thanks in advance.
I faced the same issue where 'Needs Review' tab appeared empty after the workbench moderation state for conten type is set to 'Needs Review' or 'Draft'by the creator.
I applied a patch from drupal.org and it worked. Please find the below patch and apply it in your Workbench Moderation module.
