Cannot add a row to a database using generated PHP - possible bug?

Question

Sorry if this is the wrong forum, but it seems to straddle a few different technologies.
First, I followed this tutorial to generate PHP scripts for access to the databases:
http://directormx2.com/devnet/flex/articles/flashbuilder4_introspector_php.html
Next, I tried to add a button to add a row to the table. Here's my event handler, which seems to have no effect - even after restarting my program.
protected function buttonAdd_clickHandler(event:MouseEvent):void
var user:User = new User();
user.ID = 1000;
user.FIRST_NAME = "Test";
user.LAST_NAME = "User";
user.DISPLAY_NAME = "hey you";
user.COMPANY_ID = "2";
user.LOGIN_ID = "100";
user.LOGIN_PASSWORD = "xxx";
user.DEPARTMENT = "dept";
userService.createUser(user);
I discovered that if I right-clicked on Data/Services > UserService > createUser(item: User) : int, I could select "Test Operation..." and call the service function manually. I selected the "..." under Enter Value, entered the following data into the dialog, and verified that it was added to my database.
ID:200,
FIRST_NAME:"test",
LAST_NAME:"hey",
DISPLAY_NAME:"hey",
COMPANY_ID:2,
LOGIN_ID:100,
LOGIN_PASSWORD:"xx",
DEPARTMENT:"xxx"
What's weird to me here is that COMPANY_ID and LOGIN_ID are strings, not integers, and yet if I use quotes on these fields the data is rejected (the OK button is not available). I can't assign ints to user.COMPANY_ID or user.LOGIN_ID in my MXML code, since these are declared as strings. Maybe this has nothing to do with the problem, but it seems suspicious to me.
Any help would be greatly appreciated! If it's not blindindly obvious from my post, I'm not a PHP programmer, but am trying to build the simplest of RIAs. Thank you.

Answer 1

SOLVED.
The answer is: When I took the server out of the pool to use it for another project, I configured my SAN to remove the LUNs that were shared between my Oracle VM servers. After reinstalling Oracle VM on that server, I failed to present the LUNs to it again. After fixing that, the server rejoined the pool with no problem.
