Strange Behavior in Purchase Order and Service Type Items

[Juan Pablo]

Hello Community.

I´m testing Ofbiz Trunk (ofbiz-trunk-current 14-12-09) on Oracle 10g and Red
Hat Linux 5 Server.

I found a strange behavior in Purchase Orders of service type items
(Services Orders).

1) I created a PO with a service type item. The status list looks normal
Created - 2009-12-17 17:24:54.587   By - [juanpa]

2) I approved the PO. You see the 2 last status. They´re strange.
Approved - 2009-12-17 17:25:03.349   By - [juanpa] --------------
 Completed - 2009-12-17 17:25:03.280   By - [juanpa] ------------

3) I completed the PO. I clicked "Completed Order" link.
