f: param does not work for me! What I am doing wrong?

I joined f: parameter label component h:commandButton as follows:

< h:commandButton id = "commandBtn" value = "Reserve" action = "#{avlbleTrucksBean.storeData}" >

< f: param = name value = "#{String.valueOf (truck.theIndex)"currentId"}" > < / f: param >

< / h:commandButton >

Yes, truck.theIndex is an integer.

I want to get the value of param and use it in the managed bean, but I'm not able to get the value.

The managed bean is as follows:

@ManagedBean

@SessionScoped

@Named ("avlbleTrucksBean")

/ public class AvlbleTrucksBean implements Serializable {}

private int currentId;

getter and setter methods

public int getCurrentId() {}

return currentId;

}

{} public void setCurrentId (int currentId)

this.currentId = currentId;

}

public String storeData() {}

FacesContext fContext = FacesContext.getCurrentInstance ();

this.currentId = Integer.parseInt (getCurrentIdParam (fContext));

System.out.println ("currentId is:" + currentId); It does not print the value! Why?

}

Get the value of "f: param.

public String getCurrentIdParam (cf FacesContext) {}

Map < String, String > param = fc.getExternalContext () .getRequestParameterMap ();

Return param.get ("currentId");

}

}

Well, I've always used

    Hot Mail (which I don't like) seems to work.

    On E-mail MSN - Cannot send or what I get Emails (all once in a while, we get... and when I go to Hotmail... arrived at 22). Spoke with 13 technicians, deleted all files (alt/shiftF9) 7 times. Some of the questions:

    MSN Inbox (on top left over files) continues to go to the yellow throttle and says I am offline and yet I am on line. Connection errors are the following: 0x80072efd / 0 x 0 80191002 / 0x80072eff deleted trash e.a. returns every time. Mark an unread Email and it is deleted. Tons and tons and tons of other issues. Microsoft Techs seem to be stuck on Shift/Alt/F9 and nothing is improving and sometimes gets worse... as the last time I alt/shif/F9...folders came back but old e-mail appears. Electronic mail in white and empty window. Super slow navigation & usually stops and tell me that I'm not online. Diagnosis of micro said: I am and contact MFG. A tech admitted that a new server is entered in questions. But 6weeks and I pay for the service? A tech says it's at my end frustrated, I got another PC, downloaded my MSN dialup and now... I stillHAVE questions about the addition of the computer. The 2 computers are not connected. Stand alones. Telephone lines checked. Audited modems. Microphone seems to keep secrets. And obviously can't solve my problems. Visibly frustrated spendinging 15 hours on the phone, and tired of the Microsoft Music on hold. Should I cancel? Today, same hot mail was. Using Internet Explorer, I get ERROR 500 messages or a web page from Microsoft to the particular address no longer exists. Unable to navigate while using MSN Internet Browser.

  • How can I fix the "drag and drop" feature in Windows 7? It used to work, but now does not work, for no apparent reason!

    How can I fix the "drag and drop" feature in Windows 7?  It used to work, but now does not work, for no apparent reason!

    What happens when you try?  Make sure you drag the icon image and not the text of the name.

    If it still doesn't work there are some registry changes that can try to alleviate the problem.  But because the changes to the registry are tedious and dangerous, I recommend to leave the system to repair it for you.  Here's how:
    1. Type of restore in the search box of the start menu to find and open to restore system files and settings from a restore point.
    2. Click Next, choose a date before the problem started, then click Next once more.
    • This process only takes around 2 minutes and only restores your system files/settings: it will not affect any of your files, documents, photos, emails, or anything else.
    If the system restore does not resolve the problem try this to replace missing or corrupted system files.  Here's how:
    1. Type cmd into the start menu search box, and then press Ctrl-Shift-Enter to launch as administrator.
    2. At the command prompt to start the File System Check, type sfc/scannow .

    Hi SteliosArmenis,

    Thank you for keeping us posted on the State of the question.

    I see there is that the antivirus installed on the computer could not detect infections. To ensure that the computer is clean, we can run a thorough scan using Windows Defender in offline mode.

    I suggest to download Windows Defender Beta offline to a flash drive, CD, DVD or USB and then perform the steps.

    The articles explain how to create a disk and run the scan.

    NOTE: the program must not not to be run / run from the office.

    Note: the data files that are infected must be cleaned only by removing the file completely, which means there is a risk of data loss.

    Single-pass does not work for Web sites after the last update of firefox. This works in IE and Chrome and it works under windows (when starting the computer), but not with any website in Firefox.

    Firefox 30 spent some less commonly used "Always turned on" plugins "asking to activate. To check and change this to SimplePass, you can use the page modules. Either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

  • Firefox Sync does not work for Tablet Android Nexus 10.

    Firefox Sync works for 2 PCs, but does not work for an Android tablet. It is said, that the tablet was connected successfully, I checked the bookmarks and history options to be synchronized and or bookmarks, or history of the browser has not been updated on my tablet.
    No errors. Anything not came to the Android device.
    I tried with 2 different synchronization profiles - same story for the second profile.

    Please note that we are currently living with Sync server issues. Our technicians are working around the clock to the question of setting and ensure that it works at its best. The current option is to try to keep synchronized and if you are able to synchronize properly, we recommend to not not to sync more than once every 2 hours.
