What is an elegant way to get parameters?

Is there an elegant way to get parameters?
I set the id for a parameter on the jsf page and then I can find the parameter by iterating through the parameter map searching the strings until I find the keypair that I need then I grab the value that was submitted on the form.
For example, I set id=gpaNbr but the string in the parameter map is id0:gpaNbr --- it's got that little "id0:" thingy prepended to the string.
Can someone suggest a less clumsy technique?
Thanks,
Al Malin

Sorry, forgot to mention it's for JSFs with 10.1.3 dp.

    The first time I attempted to install ML was on a late 2011 MBP.  It ran for three minutes then gave me the error message: Could not install OSX due to an unexpected error.  I was using the original ML install app, not a USB or other drive.  
    After a couple of restarts wiht the same result I saw a message to the effect that the install was trying to close open apps.  I closed apps  manually a few times to no avail.  I shut down instead of restarting then booted into Safe mode (hold down the shift key when starting) and that did it.  The install went smoothly after that. 
    I since installed ML in two iMacs using a cloned copy of the install app on a USB drive.  This time I shut down the computers and booted into Safe Mode first and there were no problems. 
    I don't know if this issue is the one causing you these problems but it is a simple enough solution to try.

  • HT1349 I lost/had my iPhone stolen. Tried using Find My iPhone and it's offline. It was set up. What do I do now? Do I report it stolen? What is the best way in getting back my iPhone if any? Thank you in advance.

    Tried using Find My iPhone and it's offline. It (Find my iPhone) was set up. What do I do now? Do I report it stolen? What is the best way in getting back my iPhone if any? Thank you in advance.

    Find My iPhone is good for misplaced iPhone but not good for thief and it was never meant to be.
    You chance of getting it back is very small.
    There are a few things you can try.
    Try remote lock/wipe your iPhone through Find My iPhone.

    You can report to the police, cell carrier (expensive cell charges for international calls, roaming etc)
    Change all the passwords used in iPhone: Apple ID, E-mail, Bank Account ....

    There is no automatic way to generate XML documents from an arbitary set of relational tables using the information contained in an XML Schema. Typically the easiest way to generate XML from relational data is to use the SQL/XML operators (XMLElement, XMLAGG, XMLAttribtues, XMLForest). There are many examples of using these operators in the forums You can validate the generated XML against the XML Schema by registering the XML Schema with XML DB and then using the XMLType.SchemaValidate() method

  • I recently added my old mac hard drive to a new macbook with an SSD as my main OSX drive.  I am having trouble with permissions in viewing my old hard drive.  What is the best way to get complete access to my old hd installed in my new Macbook?

    I recently added my old mac hard drive to a new macbook with an SSD as my main OSX drive. I am having trouble with permissions in viewing my old hard drive, when I save a permission when I reboot the full access is changed again .  What is the best way to get complete access to my old hd installed in my new Macbook?

    Open the Get Info window for the old drive. Click the Lock icon on the bottom of that window and type in your password. In the permissions area click the Plus sign ( + ) and Add your Username to it and set it to Read & Write. Close that window. you should now have full access to all the files.

  • What is the fastest way of getting data?

    With a scanning electron microscope, I need to scan a 512*512 pixel area with a pixel repetition of 15000 (two channels), meaning averaging over 15000 measurements. Simultaneously I have to adjust the voltage output for every pixel.
    I am using a 6111E Multifunction I/O board in a 800MHz P3. The whole task has do be done as fast as possible (not more than 20 minutes altogether).
    What is the fastest way to get this huge amount of data with averaging and output in between? (E.g. do I use buffered read with hardware triggering or is there a faster way?)

    Using the NI-DAQ API (not LabView) will give you a significant amount of more control over what happens and when to the data stream; which translates to a more efficient program. But you need to program in C/C++ or Delphi then. The Measurement Studio provides ActiveX controls that are like the LabView ones for C&C++ (they�re slow like the LabView ones though � not a lot you can do about the Windows GDI).
    What are you trying to sample 15000 times? The 512*512 pixel field?
    That�s almost 15Gigs of data! And it means you need to process data at 12.8MB/s to finish it in 20 minutes. I hope you know C, x86 assembly and MMX.
    I would setup a huge circular buffer (NI-DAQ calls them �double buffers�), about 30 seconds worth or so, to use with SCAN_Start. Then I would proces
    s the actual buffer the card is DMA�ing the data into with a high priority thread. Progressively sum the scan values from the 16bit buffer (the samples are only 12 bit, but the buffer should still be 16bits wide) into a secondary buffer of DWORDs the size of the screen (512*512), and you�ll need two of those, one for each channel. Once the 15000 scans are complete, convert each entry into a float divide by 15000.0f, and store it in a third buffer of floats.
    If you wish to contract this out, send me an email at [email protected]

    What is the BEST way to get my macbook with lion on it, to communicate with my Canon 40D camera? It says the utility disk is a PowerPC app and that is no longer supported. What do I do now? I can't upload photos from my camera.

    Also, I had the same problem happen when I tried to install an older version of Corel Painter. Are Macbook Pro users just NOT supposed to be able to use their laptops for the purposes they are best designed for?

  • Iphone 4s coming friday, what is the best way to get the notes content from iphone 4 to 4s without doing a restore? i want the new phone to be totally new but not sure how to get notes content across.

    What is the best way to get the notes content from iphone 4 to 4s without doing a restore? i want the new phone to be totally new but not sure how to get notes content across. If I do a restore as I have when previously from one iphone to another it has shown (in settings, usage) the cumulative usage from previous phones so all the hours of calls on all previous iphones will be displayed even though its brand new. Anyone know how I can get my notes (from standard iphone notes app) to my new iphone 4s without restoring from previous iphone 4. Thanks for any help offered.

    First, if you haven't updated to iTunes 10.5, please update now as you will need it for the iPhone 4S and iOS 5.
    Once you're done installing iTunes 10.5, open it. Connect your iPhone to iTunes using the USB cable. Once your iPhone pops up right click on it. For example: an iPhone will appear and it will say "Ryan's iPhone."
    Right click on it and select "Backup" from the dropdown menu. It will start backing up. This should backup your notes.
    Please tell me if you have any problems with backing up.
    Once you backup and get your iPhone 4S, you must follow these steps. If you don't follow these steps, you will not be able to get your notes on your new iPhone 4S.
    Open up iTunes again then right click on your device (iPhone 4S). Once you do you will see a dropdown menu. It will say "Restore from Backup..." Select this and it'll ask for a backup, select it from the dropdown menu. For example "Ryan's iPhone - October 12, 2011." Pick that and it will restore to your backup. Do this when you get your iPhone 4S so you will not lose anything. Even though you're restoring, you're getting back, since you're getting the previous settings, notes, contacts, mail and other settings from your old iPhone. You'll still have Siri though! So, restore when you first get it. Also frequently backup your device, as it will be worth it. You can restore from a backup if something goes wrong or save your data for a future update.
    Once you do that, you should have your notes on your new iPhone 4S and iOS 5.
    Please tell me if you need any help.
    I hoped I answered your questions and solved your problem!

  • HT4260 I have an AirPort Extreme and a linksys router. What is the best way to get 6-8 wired connections with ac speeds?

    I have an AirPort Extreme and a linksys router. What is the best way to get 6-8 wired connections with ac speeds?
    Appreciate your assistance.

    The answer depends on whether the AirPort Extreme is your main router....or...the Linksys device is your main router.
    In either case, the two devices must connect together using a wired Ethernet connection using CAT5e or CAT6 cabling.
    Any version of the AirPort Extreme produced within the last 5 years will have Gigabit Ethernet ports. In order to get the same speeds from the Linksys router, it will also need to be Gigabit Ethernet capable.
    If you need additional Ethernet ports, you will need to add a Gigabit Ethernet switch to either the AirPort Extreme or Linksys router.
    It is assumed that your other devices connecting to the AirPort Extreme and Linksys router will also have Gigabit Ethernet capability.
    Not sure why you mention "ac" speeds in your post. This relates to wireless connections, not wired.

    What is the best way to get a time capsule to work with a new network name?

    Well it seems that you did not explain to us the full story.  Did you change ISP's or something? Why would it not show up anymore?
    What colour is the light on the time-capsule? If it's blinking amber, then you probably need to do a factory-reset. That should get it to show up again in AirPort Utility.

  • What is the best way to get a tune created in GB for iPad into iMovie for iPad?

    What is the best way to get a tune created in GB for iPad into iMovie for iPad?

    Haven't done it myself, but seems like the correct workflow would be:
    From GarageBand (iOS), My Songs -> select song -> Send to iTunes
    From iMovie HD (iOS), My Project -> Insert Media -> select by song name
    I'm not sure if GB creates its own playlist for tagging exported songs in your iTunes library so selecting by name would be the next-best method.
    Have you tried this?
