isInitialRender and isPostback does not work correctly.

Hi, I have a problem and I wonder why this happens...

After each request, Builder of backing bean is running again. In the constructor, I have a block that I want to run only at instantiation. I tried to solve that with isInitialRender and isPostback, but they are useless, anyone works not properly, can explain why the constructor is called after each request?

The problem is that you shuold not to put any code in the constructor of the bean. You cannot predict when the bean is instantiated, this can occur at different points in the life cycle and depends on the scope of the bean from 0.

You can use the technique where you load the data the first time it is accessed. In the Get accessor, you check to see if the value you're trying to get is zero, and if this is the case you call a method that initializes the data before returning.

  • My DVD player does not work and all the information I can find is "this device does not work correctly.

    Hi, I have Windows Vista and I use a computer laptop Dell studio. When I insert a disc into my CD/DVD drive, the drive spins and it looks like it is about to start and makes the same noise start several times and then just stops. My computer does not record that there is a disc there. If I double click on the DVD drive in 'My computer' it ejects my disc and says "insert the disc in drive E".

    I went on the 'repair' Microsoft online scanner and it told me that there is a problem, but he can fix it. In Device Manager, under CD/DVD-ROM readers I have Optiarc DVD +-RW AD - 7640S. Under device status - general - properties, it says "this device does not work correctly. He also says that I have the updated driver.

    I even uninstalled the driver as a last resort and then restarted my computer. It reinstalled the driver for me, but there was no change. Please help me!

    Hello

    Step 1: Please do all the same underneath if you did some before as is often total
    a process that solves the problem.

    Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
    Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
    RESTART this will refresh the default driver stack. Even if the reader does not appear to continue
    below.

    Then, work your way through these - don't forget the drive might be bad, could be a coward
    cable or slight corrosion on the contacts (usually for a laptop) and other issues.

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
    ends. Remove and replace, do not just tight. For laptops, you can often clean power and
    contacts data with a pencil eraser.

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
    manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

    ===============================

    Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
    Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
    do it right.

    Did you follow the Troubleshooting Guide for the reader who still does not work? There are some registry
    entries that do not fix the resolution of problems and those who "could" be the cause.

    Check with your Maker system and a device for the two possible firmware updates and the
    correct registry entries for your car.

    Here are the keys in my opinion, are those in question - for the CD/DVD drive of course subkeys as
    There will be other subkeys in these keys. Do not forget to ask involved specific keys as well as the
    Parameters.
