How to get jsp PageContext in custom component renderer

Hi,
How to find PageContext(javax.servlet.jsp.PageContext) form within the custom component renderer class?
Please help?
Thanx & Regards
Milind

Strictly you're looking which URL has invoked the new request? With other words, you want the referrer?
If so, doString referrer = request.getHeader("referer"); // Yes, with the legendaric misspelling.Be careful with this, the client has full control over what he/she sends with the headers, so also the referrer. It might be null or changed while you didn't expect that. If you want to be safe, you may consider to send the current URL as a hidden parameter along with the request.

  • How to get changes of a custom PL/SQL package updated in ISG?

    Hi All,
    I need some help on how to change a custom PL/SQL package in ISG integration repository:
    I already uploaded my custom PL/SQL package to the integration repositoy some time ago. Now I have made some changes to PL/SQL record/table types defined in the package (added some fields and removed some others). These changed record/table types are used by a procedure I already uploaded to the integration repository. When regenerating the WSDL for my PL/SQL package in integration repository I get an error that the wrapper for respective procedure can't be found. When checking up the SQL types that were automatically generated (by JPublisher) for corresponding PL/SQL types, these generated SQL types are invalid...
    So it seems that in one case JPublisher generated an empty SQL type (with no attributes). In another case JPublisher generated the SQL type with old attribute list, so it didn't adopt the changes of corresponding PL/SQL type in the package...
    Can anybody tell me how to get the changes of a cusotm PL/SQL package updated in ISG? Or is there any possibility to first remove a whole PL/SQL package from the ISG integration repository (and getting rid of all old automatically generated SQL types), so that I can newly upload my PL/SQL package afterwards?
    Thanks
    Konrad

    Thanks Daniel, for your reply...
    (-> for info: I'm a colleague of Konrad...)
    Yes, we used a higher version number - and the upload of iLDT file works fine...
    But, the problem occured when generating the WSDL...
    However, I think we have found an approach of how to get the changes of a custom PL/SQL package updated correctly in ISG:
    1. Save a copy of PL/SQL package and then delete it in the database
    2. Regenerate the WSDL for PL/SQL package in ISG (seems that all atutomatically generated JPub wrappers and SQL types are also deleted)
    3. Restart all processes
    4. Create the changed version of PL/SQL package in the database again
    5. upload of iLDT
    6. Regenerate the WSDL for PL/SQL package in ISG

  • How to get the parent of a component in fx?

    Here is an example:

        height: 768

            text: "Log On"
            font: Font {size:11 name: "Verdana Bold"}

        }I want to show something on the index.fx but I don't know how to get the parent from the child component?
    In Flex, we use parent or parentApplication, Is there a similar function in JavaFX?

    Reusing the same Tile example, I had no problems, I suppose I was doing wrong the first time:
    def IMAGES_WIDTH = 100;
    def IMAGES_HEIGHT = 100;
    var COLUMN_NB = 3;
    var ROW_NB = 3;
    var scene: Scene;
    var previews: Container;
    Stage
      title: "Test of Tile layout"
      scene: scene = Scene
        width: 500
        height: 500
        fill: Color.LAVENDER
        content:
          previews = Tile
            hgap: 10
            vgap: 10
            layoutX: bind (scene.width - previews.width) / 2
            layoutY: bind (scene.height - previews.height) / 2
            columns: COLUMN_NB
            content: for (i in [ 1 .. COLUMN_NB * ROW_NB ])
              ImageView
                id: "IV{i}"
                image: Image
                  url: "{__DIR__}clock.gif"
                  width: IMAGES_WIDTH
                  preserveRatio: true
                onMousePressed: Hide
    function Hide(evt: MouseEvent): Void
      println("{evt.node} ({evt.node.id}) - {evt.node.parent}");
      var nm: Node = evt.node.parent.lookup("IV5"); // Middle node
      nm.visible = false;
      var ntl: Node = evt.node.parent.lookup("IV1"); //Top left node
      (ntl as ImageView).viewport = Rectangle2D { height: IMAGES_WIDTH/2, width: IMAGES_WIDTH/2 };
      (evt.node.parent as Tile).hgap = 20; // Strange effect, but works
    }

    CSKA stores the basic info about the cost element
    There is no data in CSKB.

  • How to use standard validator with custom component?

    Hi folks!
    I've implemented a custom component extending UIInput. My component worked well but now I want to use a standard validator.
    How can I use it??
    regards,
    Steven

    Validation is done by UIInput.validate() which is invoked by processValidators().
    So, if you don't redefine these inherited methods they will invoke the
    corresponding validators.

  • How to get committed date for each component after availability check

    Hi,
    When I use CO02 to check material availability, I can see committed date in missing part list and missing part overview for each component in production order. I save it and use CO03 to read missing part list again. The committed date is blank?! How to get the committed date for each missing part in production order?
    Another question, committed date can be displayed in CO24(missing parts info system)? Thanks in advance!!

    Rita,
    Please check that the PP avail. check has replensh lead time turned on. If RLT is turned off & there is no sufficient stock of material, then system can only committ date of 12/31/9999.
    Once you turn on RLT, it will give you some date based on your configured avail check ( that looks at stock or purchase order or production order). That way if there is no sufficient stock of material to satisfy your order system will committ the worst case date which is the RLT.
    On CO24 unfortunately there is no field for Committ date. Hence is it not possible to view commit date. You can only view Committ quantity.
    i am sure this will help you. Else please come back.
    thanks,
    Ram

    Hi Anu
    There is a user exit that gets trigerred when you try to save a work order . The exit is 'EXIT_SAPLCOIH_009' . This exit has the structure CAUFVD_IMP which will give you all the order header values entered by the user.
    User exit 'EXIT_SAPLCOBT_001' will give all the values entered by the user including order components. Also check the package CO  amd see if there is any other function group suiting your requirement.
    hope this helps you.
