I see some problems in your JSP page.
<h:selectone_menu id="list1"
valueRef="UserNumberBean.list1">This points to item that you want to appear selected when the list is rendered, so it should point to a string. So for ex, in your code below, currenListOption can be a string. Also I see that currentOption is null.
<h:selectitems
valueRef="UserNumberBean.currentListOption"/>
</h:selectone_menu>
</h:form>
</f:use_faces>
</html> This should point to list to be displayed. Say for example list1 in your code.
Hope this fixes your problem.

How do I reset my security questions/answers? I tried what apple recommends but I do not see the option to "reset" these.

How do I reset my security questions/answers? I tried what apple recommends

You need to ask Apple to reset your security questions; ways of contacting them include clicking here and picking a method for your country, phoning AppleCare and asking for the Account Security team, and filling out and submitting this form.
They wouldn't be security questions if they could be bypassed without Apple verifying your identity.

I just went from OS 10.6 to 10.8. The arrow button is gone from the scrollbar. I do not see the option in "Systems Preference" any more. Am I missing something. If it is gone, is Apple going to bring it back?

What edition of LR 5? What edition of ACR does PSCS 6 contain. If they are not parallel (same edition number x in [5 or 8].x ), is LR making a tiff or psd rendition of the image?

HT5312 I cannot remember the answers to my security questions and I do not see the option to email the answers to my rescue email, although I know I have one. What do I do?

I cannot remember the answers to my security questions and I do not see the option to send it to my rescue email, although I know I have one. What do I do? I cannot use my account for iTunes until I answer the questions and I recently got $50 of iTunes from my parents. HELP!!

Are you sure that it's a rescue email address (it's not the same thing as an alternate email address) ? If you do then you should be able to go to https://appleid.apple.com/ and click 'Manage your Apple ID' on the right-hand side of that page and log into your account. Then click on 'Password and Security' on the left-hand side of that page and on the right-hand side you might see an option to send security question reset info to your rescue email address.
If you don't have a rescue email address then see if the instructions on this user tip helps : https://discussions.apple.com/docs/DOC-4551

Make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
User/Home()/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home()/Library/Caches/com.apple.iPhoto folder.
Click to view full size
3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.

When I have video clips on my timeline, they do not play in the monitor screen. I hear the sound track but can not see the image. To test if my new files are somehow the problem, I went back and used video files that I used successfully a year ago, and they no longer play in the monitor window. I hear the sound track, but do not see any video. Have I changed some setting that controls video playback in the monitor window?

Thanks for the follow up.
Missing in this equation were the version of Premiere Elements that you were using and the computer operating system on which it was running. But...
The deed is done. But.....Until now and after you went ahead and moved to version 12, we now learn what version of Premiere Elements you were using. We still do not know the computer operating system involved.
You just said Premiere Elements 10. Premiere Elements 10 is hit by a serious known display issue if the computer uses a NVIDIA GeForce video card/graphics card. In this issue, the only remedy is to roll back the driver version to about May 2013. The description of the problem and how to do the roll back are described in one of the Announcements at the top of this forum. What video card/graphics card does your computer use?
On another front, Adobe will be releasing a new version of Premiere Elements any day now. No one but Adobe knows the feature set for the new version. That type of information is announced at the moment of release of the new version.
So the remedy to the problem that you presented in this thread could have been...
1. Rolling back the NVIDIA GeForce driver version to about May 2013 if possible (Windows 8 or 8.1 64 bit, may not be possible)
2. Move to another version of Premiere Elements (which you did)
I offer the above for consideration so that you can review your decisions. We are pleased to learn that Premiere Elements 12/12.1 works for you.
Please do not hesitate to ask questions and ask for clarifications, but remember that the answers are in the details.
Best wishes,

I can not see the PC I'm connected to over VPN in the MY Network tab.

Hi,
I have set up my incoming connection for my VPN
on a Windows 8.1 PC. I can then remotely log in with my Windows 7 laptop. The laptop establishes a connection and says that I have "ipv4 internet access."
The problem I'm having is that I can’t find the PC in my network. What am I missing? Is Windows 7 not compatible with Windows 8.1 over
a VPN? I have turned off my Norton's Firewall for a short period of time but this did not change anything. I have altered the IP range allocation for the incoming connection and this has helped to establish a stable connection.
Any ideas on why I can not see the PC I'm connected to, in the (MY
Network) tab, would be much appreciated. Thanks

Hi Steve,
The main issue is the Windows 8.1 machine is not listed in the Windows 7 machine via VPN ,right ?
Please check the following settings in the network and sharing center:
1.Check these settings in the Advanced sharing settings
“Turn on network discovery” and “turn on file and print sharing”
2.Ping the destination machine both with the IP address and the UNC to have a check .
Best regards

Brand New RD240 ThinkServer can not see the LSI 8708EM2 RAID Controller During Bootup

I have a brand new out the box RD240 ThinkServer that can not see the LSI 8708EM2 RAD Controller it came with. This RAID controller simply does not want to function. This RAID Cntroller does not show up during the boot up and I even tried putting in a different slot in the riser card, thinkn maybe it was a bad PCI-e slot, but made no difference. Also the Lenovo Easy Setup software does not find this controller either. So I'm wondering if there is an issue with the RAID Controller or is it a bad Riser card? Does anyone have any idea's on what can be done or what I may be missing?

Can not see the data in the grid

Hi,
nice to see the new features, but I can not see the the table inserts
in the data grid - the <data> rider is not clickable.
Regards

Hi annerose,
This problem has appeared in a few other threads. It's caused by installing Release 2 Raptor over Release 1 Raptor without first deinstalling Release 1 Raptor . So what you need to do is:
1) Back up any important Raptor files, e.g. connections etc.
2) Remove the existing Raptor Rel 1 installation folder
3) Install Raptor Rel 2
Hope this helps
