Jsf 1s phase of life cycle how knows ths components of the jsp with jsf tag

i wish to know how faces servlet knows the jsp s view components while creaTI NG component tree at first request to input jsp which may have jsf tags.in the first phase faces servlet doesnot know input jsp with jsf tags what componnets it has. it is actually atthe response send or forward time which is the final phase when the tag ge executed and output is sent to client.i did understandin jsf life cycle in 1 st phase component tree is created at first request in 1 st phase .

Hi,
though a FacesContext holds the values used by a request, it doesn't mean it lives for as long as the request. The best explanation I found is from the JavaDocs
release
public abstract void release()
+Release any resources associated with this FacesContext instance. Faces implementations may choose to pool instances in the associated FacesContextFactory to avoid repeated object creation and garbage collection. After release() is called on a FacesContext instance (until the FacesContext instance has been recycled by the implementation for re-use), calling any other methods will cause an IllegalStateException to be thrown.+
The implementation must call setCurrentInstance(javax.faces.context.FacesContext) passing null to remove the association between this thread and this dead FacesContext instance.
Throws:
java.lang.IllegalStateException - if this method is called after this instance has been released

    how do i connect to the internet with my ipad?

    Did you turn WiFi on in the Settings App? If WiFi is turned on, your iPad should be able to see any WiFi networks that you can connect to and you should be able to tap on one of those, enter a password if needed and then tap the join button.
    I get the feeling that you know this and the problem needs further explanation so ... Can you explain in more detail?

    i have apps to be updated but when i try to update them a message pops out saying "You have updates for other accounts, please sigh in with the other id". Can some one help me how can i still update the same with the new apple id ive created. As i dont have the access to the earlier id anymore.

    You cannot. The apps are assigned to that Apple ID and there is nothing you can do to change that. You could choose to download them again with the new Apple ID, any paid apps will need to be purchased again.
    Hope that helps.

  • How do get rid of the Pop Up Info Tags?

    This might sound Stupid, but how do get rid of the Pop Up Info Tags? that keep coming up on the Mac when in an Application that says what this item is for. This drives me crazy, and at times gets in the way of what I'm looking at. There must be some Pref to turn this off and on, I Hope.
    Anyone?

    Simply move your cursor off the control displaying the tool tip: the tip will vanish.

    You can't. But the buyer more than likely restored it because he/she could not use your Apple ID.

    Hi, filipfirmout, and welcome to the Community,
    In the Windows version, the settings to enable this are here:
    Tools -> Options -> Advanced -> check in Use Skype to call to links on the web -> Save.
    There is also this: http://www.skype.com/en/download-skype/click-to-call/

    I connected my Canon printer to time capsule, and can print OK. However, I can't get the printer scanner to work. How do you set up the scanner with Time Capsule?

    You cannot use USB. It has to be a network capable printer.. is it?? You did not indicate how it is connected.. but by wireless or ethernet then scanning is possible otherwise not.

  • Am I able to tag a data point of a spreadsheet that is being created by a datalogging VI such that at the end I have the data with multiple tags which corelate to events during a measurement cycle

    Am I able to tag a data point of a spreadsheet that is being created by a datalogging VI such that at the end I have the data with multiple tags which corelate to events during a measurement cycle
    My final need is to take data from a datalogging VI and store it in a spreadsheet with tags that corespond to events in a subVI which is controlling motor movement. This will allow users to view all data and mark the relevent data for analysis. As usual, user want everthing but with conditions.

    Sure. What you do is take the numeric value acquired, the tags you want, and build them into an array. So now, when you write to the spreadsheet, you'll have a 2D array. One thing you have to keep in mind is that all elements of an array have to be of the same type. So if your tags are strings, you'll have to convert your numeric data into strings as well.

  • How can I automatically create the files with serie-name?

    Hello, Everyone,
    I have a question again.
    How can I automatically create the file with a serie-filename?
    e.g. I have a program, it will repeat 5 times, and every time it will create a bmp-file, and I want to let this program automatically save these 5 files with a Serie-filename like File001.bmp, File002.bmp, .... File005.bmp.
    How can I do it?`
    Thanks a lot.
    Regarts,

    I have just owned a macbook pro and trying to learn things since i have all along used windows laptop. My first question is : when there are two files i am working together, one above the other on screen, how you switch over between the two with key ?

    Hi...
    Mac OS X keyboard shortcuts
    Control-F4
    Move focus to the active (or next) window
    Shift-Control-F4
    Move focus to the previously active window
    By the way...  since you are new to Mac, click a clear space on your Desktop. You should see "Finder" top left corner of the screen in the menu bar.
    Click Help then click Help Center
    As an example type in    keyboard shortcuts
    You can use the Help menu for almost any application on your Mac.

  • How to have ItemId in the URL in JSF based application

    I have a JSF based application and I am using faces-config.xml to navigate and I am using /redirect to navigate form case to case.
    The application lists products and upon selecting one, a product detail is displayed. I would like to have productId as part of the page URL so that URL can be emailed and the receiver can paste the received URL into browser and retrieve the product detail.
    Currently the URL is not rewritten to have session id in it.
    I am not ever sure where to start on this.

    Is this line correct?
    <value>#{param.productId}</value>
    Try it out yourself ;)
    This is clear and helpful. However I don't know how
    to create this URL
    (http://example.com/shop/products.jsf?productId=100)
    in the first place. The URL I have is in the form of
    http://example.com/shop/products.faces.
    Is adding '?productId=100' to the URL something
    configurable or it has to be done programmatically
    via URL rewriting?You can implement it in several ways:
    JSF<h:outputLink value="products.faces">
        <h:outputText value="click here" />
        <f:param name="productId" value="100" />
    </h:outputLink>
    <%-- or --%>
    <h:outputLink value="products.faces?productId=100">
        <h:outputText value="click here" />
    </h:outputLink>Or write a servlet listening on /shop/, scan the current request URI for product.faces, get the productId from the backing bean's session and rewrite the URL using request.getRequestDispatcher("product.faces?productId=" + productId).forward(request, response).
    Maybe there are more clever solutions using configfiles, but I don't have much experience (yet) with such GET request thingies in conjunction with JSF.

  • How to populate data before displaying jsp in JSF ?

    I have the following situation :
    In my app, i have a couple of left-navigation menus, when i click on one of them, i need to show some history data. So, i first need to call a managed bean on click of the link, fetch data and forward to history jsp page.
    How do call the managed bean directly (like struts action page) before going to JSP first ? Whenever i give a link to "something.faces", it goes to the jsp directly ?

    There are two solutions on my mind. The first is to use the Shale ViewController where you got prerender() method and in it you could fetch the data. The second solution is to fetch the data in the getter method of your property but remember that the getter method could be invoked more than once per request so putting expencive code in it could be dangerous. Use singleton instance of the fetched property, something like:
    getMyProperty() {
    if (myProperty == null) {
    .... fetch the data
    return myProperty;
    }
