Can't navigate to Macintosh HD

After a great deal of agony, I've finally installed Lion. However, now I am unable to navigate to Macintosh HD, my root folder. The highest level up I can go is my user home folder. Super. As time goes by I feel I have less and less control over my own computer with Apple.

Do you mean it's not on the desktop anymore? Please explain
Well it isn't on the desktop anymore, no. But I used to be able to navigate to it in Finder too. It was listed on the left. I thought the file hierarchy was Macintosh HD > user home folder > desktop. Can't get back past home folder, but there are all sorts of things in the Macintosh HD root folder, libraries for LaTeX and so on, from which I'm now cut off.

when I run the application, HelloWorld.jsp can be displayed correctly, but when i click the "GoodBye" button in the HelloWorld.jsp, the page can not skip from current page to GoodBye.jsp, I noted that, the URL in my browser is: [http://localhost:8080/JavaServerFaces/faces/Charpter1/HelloWorld.jsp;jsessionid=D7F83C0F448E5B5AAD5897BEB5667A67]
Then I try to replace the "GoodBye" button's action with "success" directly, but the problem is still occured.
I could not know how this problem is caused, could you help me?

This is over 3 years old. It would be smart to upgrade to the most recent version. Get it here: [http://javaserverfaces.dev.java.net].
I think the problem of navigation does not have a relationship with the current jsf API version I used.
[lot of unformatted code]Please use code tags to post your code. They will be nicely formatted and better readable. Press the CODE button to get them.I have used the code tag to format my code.
I could not know how this problem is caused, could you help me? Add <h:messages/> to the page to get notified of any missing validation or conversion errors. Verify using the JSF manual/tutorial if the navigation case is correct.In HelloWorld.jsp, I have used the <h:mesage/> and when I click the GoodBye button, the HelloWorld is refreshed only, there are not any error messages or validation messages displaied on the HelloWorld.jsp page.
I will repaste my code with code tag,

How can i navigate via navigational link between views in different windows

hello
i am using CRM_UI and have opened a popup
gv_transcr_popup is a attribute referrring to if_bsp_wd_popup in my implementation class
gv_transcr_popup = comp_controller->window_manager->create_popup(
    iv_interface_view_name = 'AIC_CM_TRANS/AssignTranspReq' "#EC NOTEXT
    iv_usage_name          = 'CUBAssignTransporReq'         "#EC NOTEXT
    iv_title               = lv_title ).
get instance of BOL dynamic query
lo_qs = cl_crm_bol_dquery_service=>get_instance( 'BTQAIC_CM_TRANSPORTREQ').
gv_transcr_popup->set_on_close_event( iv_view = me iv_event_name = 'AssignTranspReq' ).
gv_transcr_popup->set_display_mode( if_bsp_wd_popup=>c_display_mode_surrounded ).
gv_transcr_popup->open(   ).
through the iv_usage_name i will open in this popup a search view from another window
in this window is a searchview implemented and now after selecting the line in the result view in want to navigate through outbound plug / inbound plug to the starting view .
but i get the exception
Target view AIC_CM_TRANS/TransportReq of the navigation is not assigned to the current window AIC_CM_TRANS/AssignTranspReq ( which is true)
now the question: how can i navigate between views of different windows?
Best Regards

Disk utility can't repair the Macintosh HD, asking toback up all files as possible? and how to reformat the disk?

disk utility can't repair the Macintosh HD, asking toback up all files as possible? and how to reformat the disk?

Some problems can indeed be fixed this way. But working from Recovery_HD or Disk Warrior DVDs and working in the restricted environment those provide can be difficult. You can literally spend days working on this problem (while your regular work is unavailable) only to discover the old drive is unsalvageable.
There is no way to know up front whether you are facing a major Hardware failure or a minor software glitch, or something in between. Often you are forced to work from the drive you no longer trust. I continue to recommend you do this work from a different, fully functioning Mac OS X booted from a different drive.
If you have had the foresight to (as The hatter often recommends) clone your virgin install onto another drive for use in such situations, you will be able to recover from such problems in record time. If not, my previous recommendations stands:
Buy a new Drive. Or two. Install Mac OS X from scratch on a new drive, and get your Mac running again. Later, you can use the full power of Mac OS X to attempt to rescue your data, if needed. Then Zero the old drive, to see if it can hold data again reliably.
If the old drive eventually provides some needed data, and is salvageable, Merry Christmas.

On a Mac, can you navigate menus with one handed key strokes like Windows?

On a Mac, is there anyway to navigate menus with one handed keyboard strokes like you can in Windows? My girlfriend is a graphic designer and switched from Windows to Mac. She misses being able to use the Alt key and make menu selections. On Windows she can press "Alt" and then move through menus and submenus with one hand on the keyboard. When you press "Alt" the first letter of every menu is highlighted. When she presses a certain letter the menu drops down, and the first letter of every submenu is then highlighted. She can then navigate through all the submenus until she hits the selection she wants, all using the left hand on the keyboard. It's very fast and efficient. Can you do something similar to this on a Mac?
The reason she wants to do this is because when she is in Photoshop, she likes to use her right hand on the mouse with the cursor inside the canvas (sketching, moving layers around) while she makes menu commands with the left hand. It is 10 times faster this way than using the mouse for everything. Hot keys are not the same because you must have those memorized. With the "Alt" key function, you can open a drop down menu, see the choices, and make your selection.
I have been a Mac person my whole life, and I have to say, it's a pretty awesome function. I really want the Mac to have something similar.

[Actual studies|http://www.asktog.com/TOI/toi06KeyboardVMouse1.html] have found it is faster to use the mouse to make command activations than using keyboard shortcuts.
The 20-year-old argument on that web page isn't very convincing. Keyboard shortcuts are certainly faster for experience power users who do the same thing every day. The mouse is faster only for new users or users doing non-repetitive commands every day.
It is interesting that one of the posts on that page said this:
I remember one mainframe company in the sixties that came up with the following command-key guidelines:
Use the first letter of the command word
If the first letter is already used, use the last letter
If the last letter is already used, use the second letter
If the second letter is already used, use the second-to-the-last letter
etc.
This is actually very similar to how the keyboard-driven menus work in Mac OS X. The advantage over the Windows method is that when there is more than one command in a menu that shares the same first letter, you do not have to memorize which command uses which letter. You just type ahead until the correct command is selected.
I would, however, encourage Derek Doublin1's girlfriend to learn the direct keyboard shortcuts in Photoshop. On Mac or PC, for me pressing Command-Option-I is much faster than either the mouse or using the keyboard to drop the Image menu and walk down to the Image Size command.

HT1338 For whatever reason, I can't use (mac) mail on G5 with Charter. Would like to try Thunderbird (TB) -now using Firefox 3.6.28. But can't navigate through Mozilla to find older versions of TB. Other alternatives

For whatever reason, I can't use (mac) mail 3.6 on my mac G5 with Charter ISP. I would like to try Thunderbird (TB) - I'm now using Firefox 3.6.28. But I can't navigate through Mozilla to find older versions of TB. Can you suggest a URL for down loading older versions of TB, or, other alternative email programs?

I have recently moved from Thunderbird to SeaMonkey - much better and up to date with the latest Mozilla code.
See my SeaMonkey page at: http://links.zero.eu.org/seamonkey/
For PPC - download the latest SeaMonkey-ppc from:

For Intel - download normal SeaMonkey from:

Old versions of Thunderbird can be found here:

The latest Thunderbird for PPC is 3.1.20.

How can we navigate between two windows of same component in webdynpro ABAP

Hi
how can we navigate between two windows( not views ) of same component in webdynpro ABAP. its an urgent requirement
Thanks in advance.
Regards
Laeeq

Hi Laeeq,
You cannot navigate between windows of one component. You can only call a dialog box showing the contents of a second window, or you can embed the contents of a window of a different component.
Just add all the views you need to the one and only main window of the component.

If You want to make a window DEFAULT follow these steps
1) Suppose if you have 2 windows say Window1 and Window2
2) Double Click on your Application
3) In Application Properties -->Interface View
you will get two interface views Window1InterfaceView and Window2InterfaceView
4) Select which ever window you want to make as default
and make your view in desired window's DEFAULT property to true

When pulling down a long pulldown menu, the menu, instead of starting a new row, will extend past the bottom and behind the browser so that I can't navigate to an item that's below/behind the screen.

When pulling down a long pulldown menu, the menu, instead of starting a new row, will extend past the bottom and behind the browser so that I can't navigate to an item that's below/behind the screen. FF should be making a second row for these long pulldown menus, right?

Nope, there is no second row. There should be a scroll arrow "button" at the bottom and the top of that drop-down to allow you scroll, or you can use the scroll wheel on the mouse scroll further down (or back up).

PC users can't navigate my site, the home page is frozen

When I publish minor changes to my site (added graphic cirles behind photos), Mac users can easily navigate my site, but PC users cannot.

I publish through Go Daddy. Thanks.
