Apex_item.hidden does not appear to be working correctly

Hi,
I am trying to build a manual MRU form based on the How to tutorial by Christina Cho.
The differences are that I am using Apex 2.2 and thus apex_item functions and that I am putting the insertion row first before the existing rows (I want most recent records first).
To simplify testing I removed the select for the existing records (there are none so far). I have the following select:
select x.problem_id,
x.person_id,
x.probcode,
x.resolved,
x.diag_date,
x.resolved_date,
x.record_status
from (
select apex_item.hidden(1,null) problem_id,
apex_item.hidden(2,:p235_person_id) person_id,
apex_item.popupkey_from_query(3,null,
'select probcode||'' - ''||description d,
probcode from problist',75,75) probcode,
apex_item.select_list(5, '1','-;1, Yes;2') resolved,
apex_item.date_popup(6, null, null, :pick_date_format_mask, null, 12) diag_date,
apex_item.date_popup(7, null, null, :pick_date_format_mask, null, 12) resolved_date,
apex_item.hidden(8, 'ACT') record_status,
apex_item.md5_checksum(null, null, null, null, null, null) cks
from dual
) x
With the apex_item.hidden, the counts apex_application.g_f01, apex_application.g_f02, and apex_application.g_f08 are equal to zero(0) when I submit the data entered. If I change the hidden functions to text functions then the counts are equal to one(1).
The bad counts appear to be screwing up the collection creation procedure too; I expect it has to do with having a null for a loop end point..
I expect that I can create a work-around with the text fields and not showing them in the report, but does the hidden function have a real bug?
Also, for the collection creation routine, what can be done when there is nothing in the arrays? What is the value of the count?
thanks,
Peter

Unchecking the Show checkbox in Report Attributes means you are asking the Apex reporting engine to not render that column on the report.
If the column in question is a apex_item.hidden() call and it is shown (Show checkbox checked), it will display a "empty" column on the report, but the values will be posted to the g_fNN array you specify.
I agree it is a little non-intuitive, that is why I always "piggyback" the apex_item.hidden() API call with a column that is going to be rendered on the report.
Something like
select
apex_item.hidden(...)||apex_item.select_list...()
...

%@ page import="..." % does not seem to be working correctly

Hi,
          I am running Weblogic 6.1 sp1 and I am having a problem with import page
          directive. <%@ page import="my.package.*" %> does not appear to be working
          correctly when I try to reference classes in imported packages (my.package,
          etc.) from the useBean tag.
          The following code works with Resin, but not Weblogic:
          <%@ page import="my.package.*" %>
          <jsp:useBean id="errorBean" class="ErrorBean" scope="request"/>
          If, I take out the page directive, and change the useBean tag to:
          <jsp:useBean id="errorBean" class="my.package.ErrorBean"
          scope="request"/>
          then the page compiles and runs just fine.
          Michael


Here's a snippet from Sun's j2ee tutorial
          (http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/JSPBeans4.html):
          <jsp:useBean id="beanName"
          class="fully_qualified_classname" scope="scope"/>
          But I agree with you, the excerpt you posted seems to include the
          useBean tag, which is misleading.

HT4053 How do I delete photos, the delete button does not appear to be working?

I have downloaded all my photos to my new IPad. I need to delete some I do not want, how do I do it. The delete button does not appear to be working?

I personally don't know of any other software that does syncing, however, you can use another cloud service like Dropbox or Flikr to house your photos, add and delete them and have them available for viewing on any device or comuter that has an internet connection.
I'm not sure why you would be having trouble not getting photos that you put into your Photo Stream Uploads folder on your iPad. Photo Stream is Photo Stream. Also, just so you know, photo management and Photo Stream have nothing to do with iTunes. Photo management on the computer is done through your photos folder and app (on a Mac, it's iPhoto). You only use iTunes to tell the sync process which items to retrieve and sync from that library. Photo Stream is completely independent of iTunes altogether.
If you want to get photos from a camera to your iPad without having to use a computer, get a camera connection kit which will allow you to physically hook the camera to the iPad, and to directly download the photos from the camera to the iPad.
You would still want to also hook the camera up to the computer to back those photos up to your photo library on your computer.
Also you might want to look into purchasing (for under $5) iPhoto for your iPad:
https://itunes.apple.com/us/app/iphoto/id497786065?mt=8
Seems like you might benefit from talking to your local Apple Store about when they might have some sessions for learning photo management and sharing between your device and computer, because what you appear to be wanting to do is all do-able. I guess I'm just missing what your issue is. You can many things with photos on your iPad, however, your device will never be a substitue for your computer for backing up and managing your photos.
So, best of luck, I hope one of the suggestions above will help you to achieve what you are trying to do.
Cheers,
GB

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Likely a hardware issue... no way around that except to get it repaired or don't use it (the button).
Try restoring to solve the switching off problem.

Xen VNC does not appear to be working/listening

Working through some issues, I am to a point where I think I should be able to install windows in a Xen VM, but when I try to connect to the session, the connection is refused. I have tried various session numbers to make sure something was not conflicting, but no matter what I do, my connection gets refused. Besides this, I have what appears to be a healthy system, but for some reason vnc is not listening or maybe it is simply not running. If I type vncserver, the command it not found, but I am not sure that is needed to function with xen or not. Any help is appreciated.

I thought I should update this with slightly more information based on my testing and findings. It would seem the most likely reason I am not able to connect to the host from my remote computer via vnc is because vnc is not listening for connections, so I am simply turned away at the door.
I have tried going into xend-config.spx and making sure the server is set to listen
(vnc-listen '192.168.0.0')
I have also tried
(vnc-listen '0.0.0.0')
The one thing I was not sure of is if something needs to be restarted between configuration changes. For me, rebooting would seem to do the same, but I am not sure if I need to run a command to re-read the configuration or not.
The one thing that is certain is that when I run "netstat -tap" I see nothing using port 5900 and because of this, it is pretty obvious I will not be able to connect.
Here are the results of a few of the commands i have found and run:

So it would seem that at this point I have sort of reached the end of the road with the stuff I know and can dig up so I am really hoping someone can help me out a bit. I also hope I am in the right forum and if not, lets get it moved because this seems to be the last hurdle I need to cross before having a functional Arch/Xen test system.

Safe Sleep Does Not Appear to be Working

Dear Forum,
I using a 2.33GHz MacBook Pro 17” 3GB RAM 10.6.2 (FireWire HDD Start up (Boot) via a FireWire 6 port hub).
I have calibrated the battery (after replacing the original) on three occasions, however the system does not restore from the point just prior to the battery turning the system off. Instead after the battery is drained completely (after 6 hours or so) and after plugging in the charger and pressing the power button I get a grey screen, then after a few seconds the screen goes black then I hear the boot up chime and the apple logo appears.
I thought the system was able to remember where it was before the battery drained.
I have used this command in Terminal:
pmset -g | grep hibernatemode
and have received this in reply:
hibernatemode 3
but as I am using Secure Virtual Memory, I read I needed to use mode 7 so I tried…
sudo pmset -a hibernatemode 7
which returned:
hibernatemode 7
so it looks like I entered the correct command.
Furthermore, it would appear that something is happening when I choose sleep, as the Mac takes anywhere up to 30 seconds to do as I ask. (This from the sounds of it (literally) is doing what it should do (writing its current state to the drive), as I can hear the G-Drive Mini working away.)
Q1: Have I entered the correct command? (I am not fluent in the language, I was merely following directions.) (Is this command correct for this Mac?)
Q2: Can the MacBook Pro enter hibernate mode when booted from an external Firewire drive (G-Tech Mini 250GB (GUID partition))?(Apple says using a FireWire Drive to boot from is OK, at least from what I have read, so I am assuming they would have looked into various usage possibilities (Hibernate (Safe Sleep) mode, one would think is a usage possibility.))
Q3 I would prefer not to use third party software (Deep Sleep, Smart Sleep) unless I am absolutely forced in to it, as this function is written into the system (therefore should work without third party controls), so can this issue be solved with the setup I have?
Q4: Have I missed the point somewhere, or misunderstood, what the hibernate mode (safe sleep) is all about and in fact I am asking too much to expect the system to remember where it was after completely draining the battery? (Yet I don’t believe I have misread the following: http://support.apple.com/kb/HT1757)
I would very much like to get this operational as you can imagine as it is an incredibly useful feature.
Thanks.

Well the solution is: Restore from Time Machine to MacBook Pro internal HDD and Safe Sleep functions correctly.
Now how do I get a bigger HDD into the Mac...
