New, unpublished but updated content, not visible

Hi all,

On our CMS-systems we have installed workbench/revisioning (D7.23, Rev7.x-1.5, WB 7.x-1.3) and everything is working OK - except for when our authors are sub sequentially editing a new post. They can work on it but if it hasn't been published (as in - ever before) they are not able to see the contents of their edits.

Author creates content
-> 'Current version' appears next to 'New concept' and 'Moderate'
=>The 'Current version' links to node/%node (no, NOT node/%node/draft) and shows the initial edit
Author edits content
-> 'Current version' appears next to 'New concept' and 'Moderate' (so still 3 tabs)
=>Still links to node/%node with the FIRST created content (edit not visible)
Author edits content
-> same issue remains

If the Editor now steps in and publishes
-> 'Published version' appears next to 'New concept' and 'Moderate'
=> Nothing else to display
Author edits content
-> 'Published version' appears next to 'View concept', 'Edit concept' and 'Moderate' (so 4 tabs)
=> So now the first tab links to the published content and the second to the node/%node/draft
Works as intended!

The only thing I come up with now (after sifting endless through the code) is to alter
function _workbench_moderation_access_current_draft
and remove the
&& !empty($state['published'])
from the final return statement.

That will give me (while not having published) a DUAL 'Current version' tab
1 -> linking to the original edit
2 -> linking to the latest edit
I could go further and re-edit the displayed tabs, but thats even more horrible. I can't seem to figure out where it goes wrong though. The code I just shot isn't supposed to be the problem (but is part of the workaround). Playing around with the info-block did reveal that
$state['my_revision'] pointed to 654 while $state['current'] pointed to 677.
Apparently somewhere in the module, because of not being published the 654 vid is being pushed - instead of neatly showing the 677.

Hope I made the issue we experience clear and someone can provide for an adequate solution and/or point/push me in the right direction.
As a side-note, we are able to view 'diff's between two versions on the moderate tab, but clicking on a revision-href redirects to the homepage (leaving an access denied on node/%node/revision/%vid/view)

Cheers,

Tom
