Hi Toby,
Let me reiterate over the problem.
The Problem:
Say I have a VersionHistory (VH) node which has a jcr:rootVersion (VR) by
default. Now I add multiple versions say V1, V2 and V3.
So the links are as follows
VH->VR->V1->V2->V3
Now, I want to delete the base version V1, so that the version history links
become
VH->VR->V2->V3
The problem is that if I delete the base version then I am unable to view
the whole version history in my application. But this doesn't happen if I
delete either V2 or V3 in the first case. The problem only comes if I delete
the base version.
Please revert back if the problem is still not clear.
Regards,
Montek
