Open a Numbers Document when it is already open?!?!?

Question

Hello,
i use Numbers (latest Version) in a little Team.
My Problem is: One User open the Document "testname.numbers". This File is located on a server. The HD has no permissions.
OK, the User has the file open. And now comes a second user on a second computer and open the same file. BUT he became no information that the file is already open. What the f*?
User A type a information in the numbers-document and save the file and close it. User B makes the same. The information of the User (A) which saved earlyer is now lost.
In Microsoft Office, the User B becomes a warning and can open the document in "read only".
Has anyone an idea, how i can have this feature in Numbers?
Please please, sorry for my bad english.
Thank you.

The thing is, I tried entering your suggested search ("network AND users") into the "Search Discussions" box on this page. I got 301 results, ranging from topics on network user accounts in the Mac OS X Server v10.5 Leopard forums to some in which the only time the word "network" was used in the post was in the phrase "not on a network" or something like it. Last night, it took around 25 seconds for the first results to appear. This morning, that took about 5 seconds.
I then used the advanced search option to limit the search to the Numbers forum. This in itself was not quick or easy because the new advanced search option to pick a forum is implemented with a popup menu of every single Discussions forum (probably several hundred of them) & the list is organized into nested categories & sub-categories. So it isn't a simple matter of just looking for "Numbers" in the "N" part of a single level alphabetical list, but finding it in the iWork '08 subcategory of the iWork category, among the 100 or so other "i" categories. That is a challenge because the list is very long, has many levels of indention, & the scroll rate is very touchy. The result is can take several seconds to find & select Numbers, & very careful positioning of the pointer to keep the list from scrolling by at an unreadable rate. In a browser window that is small & displays only a few tens of list items at a time, it borders on an impossible task.
But with some difficulty I did manage to limit the search to the Numbers forum & clicked the "Search" button. 30 seconds later (!!) I finally saw 8 results, ranked by relevance. The highest ranked post (47%) contained the phrase, "I am a single user, the file is not stored on a network." Next came your post in this thread with the phrase, "Try with "network AND users" (24% relevance). Next was your post in the topic, "Features we need to move from Excel to Numbers" (22% relevance). It does contain the phrase, "As far as I know, if a doc is stored on a network and two users try to work with it at the same time, the document will be destroyed." That is somewhat relevant (here, the document is not destroyed) & is hardly a definitive answer, instead expressing one user's experience. The next most relevant post takes us to a topic in which you ask users to run a script to test a workaround that may or may not avoid what actually appears to be a bug in the application.
The end result is that the search leaves me wondering if it even found the most relevant posts & takes a lot of effort just to perform. In part this is because of poor page design, in part because the search algorithm is simplistic, & in part because by their nature user posts rarely are definitive statements of fact.
