Tooltip for h:selectOneMenu which uses f:selectItems to display data

I want to display a tooltip when a user mouseovers over every element in a dropdown.
I'm using h:selectOneMenu for displaying the dropdown          
<h:selectOneMenu tabindex="4" id="dataList" valueChangeListener="#{DataBean.processDataSelection}" value="#{DataBean.dataSelected}" >
          <a4j:support event="onchange" reRender="dataPanel" ajaxSingle="true"/>
          <f:selectItems value="#{DataBean.dataList}" />                         
</h:selectOneMenu>
Can anyone give any solution?

There is no way with the Sun JSF Mojarra. Either implement your own Javascript solution (crawl the DOM and apply title the attribute on the options), or rise a featurerequest at the issuetracker of the Mojarra [development team|http://javaserverfaces.dev.java.net] that they should add the 'title' attribute to the f:selectItem tag and the javax.faces.model.SelectItem class.

  • I have just upgraded from a Macbook to a Macbook Air. I have been using a iomega external hard drive for Time Machine, which use a Firewire. However, Macbook Air's do not have a Firewire port and i cannot find an adaptor anywhere. Can anyone help?? Thanks

    I have just upgraded from a Macbook to a Macbook Air. I have been using a iomega external hard drive for Time Machine, which use a Firewire. However, Macbook Air's do not have a Firewire port and i cannot find an adaptor anywhere. Can anyone help?? Thanks

    There has never been a reliable firewire ---> USB adapter suitable for external high speed storage.  This was a major issue when the MacBooks lost the firewire port a number of years ago (Apple subsequently brought it back).
    The only high speed port on the Air is the ThunderBolt port.  There are external ThunderBolt drive options out there, but they're somewhat more expensive than traditional USB/FireWire options.

    I have Photoshop Eleent 12 and use a Windows PC.  I hae been using a Canon EOS 50D for several years, which uses a Compact Flash Card.  I have always downloaded pictures by using a card reader wich I connect to my computer. I Go to the Organizer, click on "Import" and select "From camera or card reader".  Once on the Photo Downloader, I select the pictures, chose the folder and click on "Get Media" and all the photos get downloaded. Today I folled the same procedure as always, but ZI'm gettig an error message that reads"Import Failed" followed by another message that reads "Nothing was imported. The file(s) or folder(s) selected to import did not contain any supported file types, or the files are already in this Catalog."  I'm puzzled by this message and don't know what to do o get my photos.  Any suggestions?

    The organizer doesn't care where you send your photos when you download them via the downloader or where they happen to be when you first bring them in if you use the Get Photos command, but once your pics are in the Organizer, you *must* move them from within organizer or it can't find them. You don't have to use My Pictures at all if you don't want to, but regardless of the folder where you put your photos, if you want them someplace else, you use organizer to do it.

  • Bex Query which uses Dynamic columns to display actuals

    Hi Bex experts,
    I have a query issue/question.
    I currently have a Bex query which shows me the the planned values for each period, spanning 6 years into the future. My Key figure columns are defined as follows:
    Value type  = '020'
    Version  = mandatory variable, entered at execution.
    Posting period (FISCPER3)  = These columns are fixed values using periods 1 to 12 for each column.
    Fiscal year (0FISCYEAR) = Each column contains SAP exit for current year, and using the offset +1, +2, +3, +4 etc, when I define the future years coulmns.
    Currency = fixed 'USD'.
    Fiscal year variant = fixed 'Z4'
    The above works fine for plan data.
    I want to now include is:
    Seperate 'Dynamic columns' to show only actuals for period ranges from period one to the previous period (or current period minus 1). Each period should have it's own column for actuals.
    The dynamic actuals columns should be grouped together to the left of the plan columns.
    Actuals are only for current year, so I will still use the SAP EXIT for current year in the column definition.
    Example: If I am currently in period 10, the query should show me actuals from period 1 to period 9 in seperate columns, then continue to show me my plan values columns that I have in place already.
    How can I construct these actuals columns in to my existing query. If you have possible screens shots.
    Thanks, and maximum points will be alotted.

    The way I have approached this you may not like as it involves quite a bit of coding
    12 CKFs
    each CKF adds up 2 RKFs
    So 24 RKFs
    example Column 6 CKF
    Adds Column 6 RKF Actual and Column 6 RKF Plan
    Column 6 RKF Actual contains Actual version + key figure + Period variable column 6 Actual
    Column 6 RKF Plan contains Plan version + key figure + Period Variable column 6 Plan
    Period variable column 6 Actual
    is a cmod variable which reads the entered date
    if the period of entered date is LE 6
    then return period 6 into "Period variable column 6 Actual"
    else put 0 into "Period variable column 6 Actual"
    Period variable column 6 Plan
    is a cmod variable which reads the entered date
    if the period of entered date is LE 6
    then return period 0 into "Period variable column 6 Plan"
    else put 6 into "Period variable column 6 Plan"
    Now what happens is that if you enter period 6 in your selection screen all the Actuals of columns greater than 6 all have period 0 put into their selection so return 0 and all the columns less than or equal to 6 return the values for the fiscal period (ie column 1 gets period 1)
    And in addition all the Plans columns return the value of their column ie for their period for those greater than 6 and for those less than 6 they all return 0
    It's convulted - but you get the idea - and yes it works
    There may be a better way to do it - and I am open to suggestions
    (this does assume that NOTHING is posted to period 0 otherwise it won't work)

  • Have You Used Bing Map to Display Data

    I am looking for anyone who has used the Bing Map API to display their BW reporting?  Would you share your scenario and experience with the API?  How was it received by your reporting developers?  How was it received by your reporting consumers? 
    I am looking for any insights you may have.
    Best Regards,
    Scott Hutslar

    Scott,
    Bing Maps API or Google Map API the concerns are :
    There are multiple ways to do it - these APIs are available as web services which you can call and you can realize them using :
    1. Third party application using data from BW and BING together - this could be platforms like FLEX / any Java Application that you can build including Web Dynpro etc.
    You can also use BSP Pages to develop the same.
    Constraints :
    the BING APi requires connection to the internet and usually the sandbox / dev systems are not exposed to the internet which leads to the usual option of doing it in a third party application like FLEX etc.
    Data from BW can be enabled using web services - typically using the Query_view_data web service or the restful web service available for queries ( search for RESTFul Query in the WIKI and you should get the wiki by Durairaj Athavan raja )
    Now when you use a third party tool - then rollout becomes an issue especially with FLEX and the crossdomain issues you will face. Using TOmcat and a custom Java application / AJAX etc would mean that you will have to look at how these applications get consumed.
    The experience is very good in terms of flexibility afforded to UI design but this would ofcourse depend on the interface or method you would use.

  • Create spool for background jobs which uses submit statement

    Hi Gurus,
                 I have a quick question regarding the backgroud jobs. When we run a program in the background , it should create a spool for us, but, the problem comes when I am running a program in the background, its not creating the spool. This program uses SUBMIT statement. This program collects the data and it will submit to the other program and then retuen. In this case, its not creating a spool. Its very important for us to look at the spool for this program. Does anybody cam across this kind of problem? I need ur inputs.

  • How do I wipe my old iphone3gs clean for my wife to use without itunes restoring the data to my settings when she plugs it into itunes?

    Hi, I have bought a new iphone 4s and want to give my old iphone 3gs to my wife. She has a sim card on the same network so she can put the sim in and use it straightaway but all of my data and apps stay on there. How can I restore the phone to factory settings for her to use without itunes automaticly trying to restore it to the back up data to my last back up?
    Thanks in advance,

    Hi,
    You will find a list of your iDevice Backups there:
    Edit (Control+,) - Preferences - Devices
    Delete the Backups you don't need anymore, but if you delete all Backups you can't restore your iPhone.

  • EPM 10 Report using Member Recognition - not displaying data

    Hi Experts,
    I’ve created a report using member recognition because I've had to combine CATEGORY and TIME in the column, all the formulas have being populated correctly for (CATEGORY + TIME), I have also saved it as an Input Form, however when I refresh the report can’t see any data and there is data for these periods and there is data.
    Another issue I have – I’ve entered 777 into 2013.003 and it automatically picks up a (PERSON RESPONSIBLE) or if I input an amount such as 999999999 then click save data, I get an error “no data to save”
    Has anyone experienced this before or am I missing an option somewhere - thx in advance
    Shane

    By algorithm I mean something like:
    if CATEGORY=SOMETHING then show only TIME
    if CATEGORY<>SOMETHING then show only CATEGORY.
    But for this task custom member is a bit complex solution, manually created headers are better.
    Look on my comment in the discussion after blog post with a complex report sample:

  • Looking for interMedia web sites using text retrieval

    I'm particularly interested in sites which use the thesaurus features.
    Thanks.

    There are many sites on the Internet that use interMedia Text for site search and for catalog search.
    While we don't track which Oracle customers use particular components of the database such as interMedia, here are a few good examples for you to try :-

    pls can anybody clear my doubt
    r there any setting we need to make in chart designer
    or any event for mouse over
    thanks

    hi,
    In that case, create an extra context attribute in that node, and dynamically assign values(text that you wanted to display as tooltip) to it.
    Then, map that context with the series element.
    Enable the "label" of the businessGraphics from the chart designer.
    The result will be that, although u will not get tooltip, but in the labels, you can display what you wanted.

  • How to use old 2005 cinema display (20'') with MacBook Air (mid-2009)

    My old 20'' cinema display (2005) has three ports coming out of its power box (single-port dvi, usb, firewire).  Is it possible to use this display with my newer MacBook Air (mid-2009) ? If so, what kind of connector do I need?  Thank you very much for your help.

    To use my old Cinema display (2005) with my old PowerMac G5 (2005) I had to plug in all three ports (DVI, usb and firewire) into the desktop.  Can I really use the display just with the DVI output plugged into my MacBook Air mini-Display Port ?
