JSF - Click twice to get actual content and data from back Bean

Hello,
maybe an easy thing ... i got a Menu wih commandLink. the BackBean sends back the "from-outcome". After I cklick on a commandLine, the page is called, but some vars are still from page befor. cklicking second time, then it works. The bad thing about this, is, I have Realm, and the LoginPage appears after I click twice. The User sees the protected<page wthout beeing logged in ...
someone has an idea?
thx.
PS.:Bean ist Session-Scope, marked as Stateful.

Hello,
thx for the answet. I debugged.
When I call with the command the next page, I call a Bean which gives back the outcome ti display the next page. the vars i'm reading, i read with another bean, called when i make the content. apparently, when i use this
context = FacesContext.getCurrentInstance();
resp = (HttpServletRequest) context.getExternalContext().getRequest();
System.out.println("Get " + resp.getRequestURI());
the display says : "/company-db/index.faces"
the page i'm go to is "registry.faces"
when I click a second time, then the display is:
the display says "/company-db/registry.faces"

Easy Custom device tool - how to get actual waveforms or data from a channel

I want to use a custom device to do the simulation for my system, but I am not sure how to get channel data to it? I am using a cRio 9024, and 6 modules for signal input and signal output. I did the walk through, but it is not connecting to channel data. Any thoughts?

Sorry that my previous response was so brief - I didn't have the opportunity to take a look at your code last Friday (and on top of that, I poorly worded my question about running your code in LabVIEW).
You would want to include logic to communicate with your cRIO in the Execute VI - you don't need to add anything to the Channel Data or System Data controls to get the data into your custom device. If you're using the Scan Engine, this would mean just dragging and dropping Scan Engine IO variables into the Execute VI and then operating on the data you read out of them. Now, if you want to pass data out of the custom device to other parts of VeriStand, you would need to add items to Channel Data for each value you want to pass out of the custom device.
When I mentioned running your code in LabVIEW, the idea I was trying to get at is creating a separate test project to verify that the logic you have implemented in your Execute VI works apart from the custom device architecture. Now that I've had a chance to take a look at your code, I see that the logic to communicate with the cRIO hasn't been implemented yet. As such, that original suggestion doesn't make sense - sorry for the confusion.
Also, just so you're aware, you'll need to modify your custom device project to allow the custom device to be compiled for a VxWorks target. To do so, add your cRIO to the project as a new target and then copy all of your custom device files to the cRIO controller. You'll also need to make some modifications to the build specification to get everything to compile correctly.
Finally, I also notice that in your init VI, you don't pass a file path to the Open/Create/Replace file VI, which will likely cause some problems when you try to run the device.

How to get current time and date??

How to get current time and date from my PC time and date to the java application??
i use java.util.* package but got error, that is:
- java.util.* and java.sql.* class are match
- abstract class cannot be instantiated
so what can i do, pls guide...thanks...

There is a method in the System class that will return the current system time. You could also instantiate a Date, Time, Timestamp, or Calendar object, all of which get created with the system time by default.
Don't import *. Import the specific classes you need.
Next time, post the actual text of the exceptions/compile errors. If you make people guess, most just won't bother.

Time taken to clear content and data

I have just cleared the content and data from my 64G Ipad1, and it has been showing the Apple icon with progress bar (with no progress at all) for the past 3 hours. May I enquire how long does it usually take??
THe ipad does not respond at all now and it worries me. Is it normal??
Thanks in advance for the inputs.

It shouldn't take but a minute or two.

Time and date from an atomic clock

Hi,
I want to make an application in Labview 6i which gets the time and date
from an atomic clock (this is a must!). What is the easiest way to do this?
Regards,
Sergio

You cannot maintain atomic clock accuracy using software on a PC. Think
about it. You're running on a PC whose clock may gain milliseconds per
day if you're lucky, probably seconds / day.
Out of the box, Windows can do things (like downloading Windows updates)
which can delay operations for seconds.
It can take several milliseconds to update an indicator that shows the
time, if that is what you plan to do.
I can see some approaches:
* If you can accept moderate accuracy of about 1-10 ms run software such
as Dimension 4 from www.thinkman.com.
That can be set up to run ever
y 15 minutes, automatically synchronizing
your PC to Internet time servers.
You don't need to control it from LabVIEW; if you had to, you could run
the executable C:\Program Files\D4\D4.exe using System Exec.
* You haven't described what you are doing. If you want more accurate
time keeping, then you might get a timekeeping board to plug into your
PC and control any other hardware you may be using.
Search the Web for "IRIG board".
Good luck, Mark

I need to erase all Contents and Settings from my i phone 5 but I forgot the restrictions passcode. How can I get it. ( Idon't have access to i tunes). Thanks.

I need to erase all Contents and Settings from my i phone 5 but I forgot the restrictions passcode. How can I get it. ( Idon't have access to i tunes). Thanks.

Not possible. You need access to iTunes.
The passcode will be required to make changes to these settings or to disable Restrictions. Note: If you lose or forget a restriction passcode, you will need to perform a factory restore to remove it.

That means either your graphics card does not support 3D or that there is a problem with your graphics drivers. See if your GPU maker has an update.

How can I move the tab bar to the bottom, and how do I get my reload and stop buttons back?

The new version of Firefox has repositioned my tab bar to the top and I cannot move it to the bottom. I tried about:config, but browser.tabs.ontop was already set to false - very curious, since this should have solved my problem in the first place.
In the new version of Firefox I cannot get my reload and stop buttons back again.

Firefox uses a combined Stop/Reload/Go button that is positioned at the right end of the location bar.
*You get a Stop button during page loading that changes to a Reload button when the page has finished loading
*You get a Go button if you modify the location bar content
*Middle-click the Reload button to duplicate the current tab to a new tab

https://discussions.apple.com/thread/2452022?start=0&tstart=0
Keep in mind that the recovered photos will not be in their full resolution, but instead will be the scaled down versions that were optimized in size and resolution to fit your iPod's smaller LCD screen.
