How to make a row enabled for lead selection and make other Rows disabled?

Hi,
What I require is:
In a webdynpro table , which can have multiple rows, I want to make the rows which are retrieved fom backend as disabled for selection.
And when I add a new row (using an ADD functionality) , this newly added row should only be enabled for lead selection.
The Table property "enabled" can be assigned a context , and can be used to control the disabling of whole table.But then if I add the new row to this table, even this will be disabled.
I can set lead selection to a the new row, but if the whole table is disabled, this won't work.
Please suggest a solution for this.
Thanks,
Richa

Do not set the enabled flag to the whole table but to the editors of each column. Bind the enabled property to a calculated boolean flag in the data source node. In the get method of this flag add a code that will make the editor enabled only if it belongs to the lead selection element.
Now do not allow the selection of rows in the table (there is a property for this, perhaps is named rows selection I don't remember well now), but change the lead selection of the data source node to the desired element when you add the element programatically.
Hope it helps.

  • My itunes is on an old computer.  So old that I can't update it and so Haven't used it in two years.  How can I move it to my new laptop and make sure this doesn't happen again?  Very frustrated that I've spend $$ but can't get my music.

    My itunes is on an old computer.  So old that I can't update it and so Haven't used it in two years.  How can I move it to my new laptop and make sure this doesn't happen again?  Very frustrated that I've spend $$ but can't get my music.
    I want so set up itunes on my laptop and make sure that I get all of my old music and any music shared from my sons' itunes accounts.  Do I have to set up itunes on my new laptop first and then use the same logins?  Really concerned about losing any music, etc.

    These are two possible approaches that will normally work to move an existing library to a new computer.
    Method 1
    Backup the library with this User Tip.
    Deauthorize the old computer if you no longer want to access protected content on it.
    Restore the backup to your new computer using the same tool used to back it up.
    Keep your backup up-to-date in future.
    Method 2
    Connect the two computers to the same network. Share your <User's Music> folder from the old computer and copy the entire iTunes library folder into the <User's Music> folder on the new one. Again, deauthorize the old computer if no longer required.
    Both methods should give the new computer a working clone of the library that was on the old one. As far as iTunes is concerned this is still the "home" library for your devices so you shouldn't have any issues with iTunes wanting to erase and reload.
    I'd recommend method 1 since it establishes an ongoing backup for your library.
    Note if you have failed to move contacts and calendar items across you should create one dummy entry of each in your new profile and iTunes should  merge the existing data from the device.
    If your media folder has been split out from the main iTunes folder you may need to do some preparatory work to make it easier to move. See make a split library portable.
    Should you be in the unfortunate position where you are no longer able to access your original library or a backup then then see Recover your iTunes library from your iPod or iOS device for advice on how to set up your devices with a new library with the maximum preservation of data.

  • How can i check my mails on the iphone and make sure that the mail wont pop up again on my computer ?

    How can i check my mails on the iphone and make sure that the mail wont pop up again on my computer/ will be deleted on the server ?

    For that kind of connectivity you need to be using an email account configured either as IMAP or Exchange.
    IMAP & Exchange accounts will maintain a sync across all your devices, so if you read / delete a message on your phone, it will disappear from the server as well. This cannot happen in POP email accounts.
    If your using gmail, instructions on how to set up exchange / imap are here http://www.google.com/support/mobile/bin/answer.py?answer=138740&topic=14252
    Alternatively, if its anything other than Google, you will need to contact your email providor or IT department (if your email address resides with an enterprise environment) to get the correct settings.
    Hope this helps!

  • "Validation" enabled for the composite and my testsuites are not working

    I have posted the below issue in Test suite in JDEV - Studio Edition Version 11.1.1.2.0 But I felt that this is the right forum, so posting this again here:
    I have mediator calling bpel. Mediator is exposed as web service. Whenever I run the service using "Test" button on EM with validation turned on
    then it works and the process will be completed.
    But I have initiate xml in the test suites. I select "UnitTests" and select my test case xml that was associated to "Initiate Message for operation",
    I see that the process is still in the "Running" state. I put in exactly the same values as I use for testing the service from EM.
    Did anybody face this issue? This happens only when we turn the validation to "Enabled" in EM.
    I have "Validation" enabled for the composite and my testsuites are not working. When I test using unit tests, I am only seeing "Running" status of the processes and these are not getting completed.

    Hello there, RevDebMN.
    The following Knowledge Base article is always a great fallback article for troubleshooting Mail issues:
    OS X Mail: Troubleshooting sending and receiving email messages
    http://support.apple.com/kb/ts3276
    Particularly useful, in your case:
    Mail Connection Doctor shows one or more red dots () in the account Status column
    Check your Incoming IMAP or POP and Outgoing SMTP email account settings
    Use Apple's online Mail Setup Assistant to discover what the correct settings should be for both your Incoming (IMAP or POP) and Outgoing SMTP email servers. If your email service provider is not listed in the Mail Setup Assistant, visit your email service provider's website or contact their support staff to get the correct settings. You can use this "cheat sheet" when asking your email service provider about the settings you need.
    After you have the correct email service provider settings, make sure Mail is configured properly.
    Click here if your Incoming and Outgoing email account settings are correct, but the issue persists
    What alert message is shown in the Mail Connection Doctor "Details" column affected account?
    Click here if a "Could not connect to this (server type) server…" message appears
    Click here if a "Trying to log in to this (email server provider name) account failed…" message or any other error message appears
    If the issue persists, then you'll want to remove the account and then add it again using this article:
    Mail (Mountain Lion): Remove accounts

    Thanks for reaching out to Apple Support Communities.

    How do a scan a file from my scanner and make it a PDF. . . . I do not see this choice in the Adobe program?
    In the past I would simply place a copy of the document on my scanner, then selected create PDF from scanner.  However, there is now no create PDF from scanner alternative, option or choice.  The only option available is selected file to convert to PDF.  what am I to do?

    That would have been a function of your scanning software. Adobe Reader is only used to view the pdf that your scanning software created.

  • How to forbid any further changes for PO (QTY and price ) after it has been

    Hi,
    How to forbid any further changes for PO (QTY and price ) after it has been done GR and LIV? Thanks.

    Hi,
    Price anyway cannot be changed once GR is posted on the PO item, it can be changed only by cancelling the GR, the same applies to IR too.
    But quantity can be changed at any time.
    So if you are looking at blocking qty too, then a customized message through save exit is the option, I am not aware of any standard SAP messages that can be configured to achieve this..

    Hope to you a very happy new year,
    I have two differnt LAP 1300 and 1200 in my network and I need to add theme to the WLC,
    I successed to add one of theme by the option 60 in the DHCP pool at the Core SW,

    How to use multiple VCI strings for lap 1300 and 1200 (option 60) in one pool?
    Thanks in Advanced,
    Ahmed,

    To add to Scott's post.  Option 60 would be useful if you needed to put certain types of AP on specific controllers.  Otherwise, no real need to use it for the most part.
    Though, I do recall an issue a few years ago that some windows machines had issues getting DHCP if option 43 is being returned.
    Now, on an IOS switch, you can only configure one option 60 per DHCP scope

  • How do I remove my card details from payment and make it none again

    need to find out how to remove my bank card from payment info and make it none again

    On a Mac or PC, iTunes>Store>click your name in the toolbar and select 'Account Info' (in older iTunes click 'Account' in the links on the right). Presumably the iOS version is similar.
    Sign in. Click 'Edit' to the right of 'Payment information. You will see various credit card types listed, plus there should be a 'None' button. Click that then 'Done' at the bottom right.
    There have been reports that some people have been unable to carry this out. In that case probably only Support can help you. Go to https://getsupport.apple.com . Click 'See all products and services', then ' 'iTunes', and then 'iTunes Store', then 'Purchases, Billing & Redemption', then 'iTunes Store account billing'.

Just type in NAS for example and you get many threads on the subject (marked with a green checkmark if it solved the question) another example would be Airport Exterme and sound system.

    How do I gwet an adapter for a laptop and Iphone to use in New Zealand and Australia?

    For the iPhone the regular power adapter will work worldwide. All you need is a plug aapter. 99% of all laptop power packs are also universal. (All Apple laptops certainly are). Look at the label. If it says 120-240 volts, 50/60 Hz it will work anywhere in the world. Again, all you need is a converter for the prongs on the plug.
