What does the scriptcollector do and how does it related to jsf lifecycle?

hi,
i want to know what does the scriptcollector do and how does it related to jsf lifecycle? and also in the scriptcollector if i call this,
preRender=#{myBean.onPageLoadBegin}
postRender=#{myBean.onPageLoadEnd}
how my page will react?

The hx:scriptCollector is part of the IBM Faces Client Framework and has nothing to do with Sun JSF RI.
Lot of the hx components require specific Javascript and those hx components should be placed inside a single hx:scriptCollector which on its turn checks the nested hx components and renders the desired Javascript for it at the end of the tag. Check the HTML source for that Javascript.

    Welcome to Apple Support Communities
    That's exactly what you need. A Mini DisplayPort to HDMI adapter and a HDMI cable. See > http://support.apple.com/kb/HT4241?viewlocale=en_US
    This is the only way to view a video on the TV. After connecting your MacBook Air to the TV, image on your TV should show immediately. Then, press Command and F1 keys to mirror your MacBook Air display, and open the video

    To add to sig's reply, "calibrating" does not calibrate Lithiu-Ion batteries, it calibrates the charge reporting circuitry.  If you look at the effect of deep discharging Lithium-Ion batteries in the data from the independent test group, Battery University, you will see that doing so shortens the life of the battery significantly. It looks like an optimum balance between use and life is at a discharge level of 50%.

  • I'm trying to use Dictation.  Where does the text go, and how can I retrieve it?  Thank you.

    I'm trying to use Dictation.  Where does the text go, and how can I retrieve it?  Thank you.

    You dictate after you open a blank page in any text editor. The text goes on the page.
    You can use Text Edit for example (in your applications folder).
    With the blank page open, go to the Edit menu and select Start Dictation. When you are finished, you save the file as you would any other document. You can retrieve it, edit it or anything else you want, because it is a file like any other you create with that text editor.

  • What's the implicit joins and how to configure it?

    Hello guys
    what's the implicit joins and how to configure it? What's the purpose of implicit and explicit joins?
    Please help
    Thank you

    Thus, on my side, I think that :
    Explicit join define the join condition between the key column from the table.
    (table1.di = table2.id)
    While
    Implicit Join define :
    * the type of join outer, inner, ...
    http://gerardnico.com/wiki/dw/join/start
    * And the relationship (one-to-many, cardinality)
    http://gerardnico.com/wiki/dw/data_quality/relationships
    And all this information are used to generate the statement (query).
    And I don't really know why you have two type of key :
    * Physical Foreign Keys
    * Logical Foreign Keys

  • When I signin Apple ID showing error 403 on my mobile. What is the reason? And how can solve it?

    When I signin Apple ID showing error 403 on my mobile. What is the reason? And how can solve it?

    This often means that the maximum of 3 iCloud accounts have already been created on the phone and it cannot create another account.  When this happens, all you can do is re-use one of the accounts previously created or creat your account using a different iOS device or Mac, if you have one.

  • What is the error 102 and how do I fix it?

    I am trying to download iOS 7 through iTunes however I needed new iTunes so I was doing the software update and it says Error 102!!! AHHH!! FRUSTRATING!! Help??? I tried restarting ...

    I did a Google search on Error 1450, and it seems to be a 'lack of resources' issue within windows. Not related to iTunes.
    Maybe shut down all other programs (including the TSR programs you may have loaded) and see if it helps?

    Are you running Firefox in Windows 95 or 98 compatibility mode?
    Mozilla/5.0 ('''Windows NT 4.0'''; rv:35.0) Gecko/20100101 Firefox/35.0
    Firefox won't install on Windows NT 4.0 - so something is changing your useragent and saying that your operating system is like 20 years old.
    Right-click your Firefox desk-top shortcut and select Properties. Then open the Compatibility tab and look at '''Compatibility mode''' - un-check that box if it has a check-mark.

  • PSE 5--what is a clipping mask and how does it work?

    Can anyone explain what a clipping mask is, how it works, and most importantly if Photoshop Elements 5.0 has this capability?
    Also, are there any tutorials out there that I can teach myself on this topic? I am trying to mimic a layout explained in digital scrapbooking magazine and this technique is used.
    Thank you!
    Heather

    Heather,
    You can find one explanation at Janee's tutorials: http://www.myjanee.com/tuts/elements/elemask.htm
    Since PSE does not support layer masks per se, the clipping group simulates a layer mask and hence Janee's name for it, "elemask" (cute, huh?)
    Here are 2 examples:
    In this example I wanted to blur the background leaving the flower in focus:
    http://www.pixentral.com/show.php?picture=1euavV1sDqzrEqqqierfc5dSEH9yI01
    1. Duplicate the Background layer and apply a Gaussian blur to the new layer.
    2. Add an adjustment layer below the blur layer (any kind of adjustment layer will do), but do not make any adjustment - just click OK.\
    3. Group the blur layer with the adjustment layer. On the adjustment layer paint the subject with black
    to mask out the blur, paint with white to restore the blur.
    Of course you can use other tools on the adjustment layer besides the paint brush, e.g., make a selection and fill with the black or white. In some cases it might be easier to first fill the adjustment layer with black and then paint with white.
    In this example (not actually a mask but still demonstrates a clipping group) I wanted to crop the picture into a leaf shape.
    http://www.pixentral.com/show.php?picture=1ys9Z7FspSwF8HHKGLrxjGVhbTodmF0
    1. Use the leaf from the Custom Shape tool to draw out the leaf, creating a new layer.
    2. Move the leaf layer below the picture layer.
    3. Group the two layers.
    Note that in order to move a layer below the Background layer you have to rename the Background layer to anything else (layer 0 in my example).
