[opencms-dev] error unlocking resource

[Giedrius Tumelis]

Hi,
I am using opencms 7.5.x

There a resource, which I want to delete, but get message, that they
are locked; and I see the lock icon in the opencms manager. But when I
want to unlock the resources, I get an error message:

--
The following resources were not unlocked:
Error unlocking resource
"/objects/bookingrequests/123_test_booking_request1337931907716.html"
by current user "Admin" - Resource
"/objects/bookingrequests/123_test_booking_request1337931907716.html"
is not locked by current user "Admin".
--

When I try to delete the resource, I get a window with a message at bottom :
"The operation can not be executed since there are resources locked by
other users."
In the middle of the window there is a table where in one column
"Name" is "123_test_booking_request1337931907716.html", and in another
"Locked by" is "Admin".

So the resource is unlocked and locked in the same time???

Help is appreciated.
Regards ..
