Object Visualization and accessing the object's attributes

Hi all,
I am trying to configure SWFVISU to allow us to call an ABAP Web Dynpro which displays an adhoc object attached to a workflow in the UWL.
I've had success with a business object of a task which is not an adhoc object by binding an attribute to the task container and creating a custom attribute in the UWL.  However this is not possible with Adhoc Objects as there could be 0..n objects at runtime.
I've seen plenty of threads that refer to using ${item.externalObjectId} as part of the visualization parameters, ie in Visualization Parameters:
APPLICATION     FMCA_WDY_FPF
DYNPARAM                          WDCONFIGURATIONID=FMCA_WDY_FPF_CONF&RETURN_ID=${item.externalObjectId}
NAMESPACE                          sap
SYSTEM_ALIAS     SAP_ERP_Public_Sector
however in this case the attribute we need access to is an attribute to the Object Class, not the Work Item.
Is there any other variable substitution we can use in the Object Visualization to reference an attribute of the Object Class itself?
Thanks in advance
Alex

  • Please tell me the way to access the object...........?

    when we are decleared a class variable,there should be an object in the memory.this object is the object of the java.obj.Class class.............
    my query is ..
    how to acess that object ?
    e.g.
    public class Basic
    public class Acsess{
    Basic b;//now please tell how access the object of class Basic.Class?......
    thanks and regurds

    I believe that the following example will help. You should also read this tutorial page:
    [Understanding Instance and Class Members|http://java.sun.com/docs/books/tutorial/java/javaOO/classvars.html]
    class A
        static String fie = "this is fie";
        String foo = "this is foo";
    public class B
        public static void main(String[] args)
            System.out.println(A.fie);
            A instance = new A();
            System.out.println(instance.fie); // Not recommended; does not
                                              // make it clear that fie is
                                              // a class (static) variable
            System.out.println(instance.foo);
    }

  • What is the Collection that returns and removes the Object simultaneously

    Hi Java Experts,
    I believe I'm looking for a Collection that will allow me to (a.) return an object and (b.) remove the object from the collection simultaneously (c) without having to specify the index location of the object. Very similar to what you can do when you enumerate through a Properties Object.
    Here is a description of why I think this is the solution that I want. - Perhaps some Design Pattern Experts can help.
    I am making an application that is supposed to loop continuously through a collection while adding more information to the collection (example: in a while(collection.size()>0){ take some action })
    The action taken inside the while loop would add more items to the collection. I'm hoping that fact would be picked up by collection.size()>0 and cause the iteration to continue.
    I am doing this solution within one thread and class. But I'm also going to let this thread feed another Class (A controller thread) with different items which are added to It's collection for it's own loop. That solution will have to handle multiple threads feeding information to it's solution.
    Here is example code below of how i'm proposing this would work in a single threaded class.
    thanks for all the help

  • I would like cut out an object using the quick select tool and drop the object into another picture. Can anyone help

    I am using background pictures and want to cut out objects from other jpegs using the quick select tool and drop them into the background picture. So if i have a banana and select the object i need to copy the banana into the other background.
    Hope this makes sense.
    Gary

    Select banana. Right click>layer via copy. Move tool. Click and drag to other file. Drop on image.
    OR: load the background and banana in one stack (File>Scripts>Load File Into Stack). Select banana and layer via copy or create layer mask.

  • How can I safely transfer my 125GB of itunes music files to free up space, but still keep itunes on my MBP, and access the music with the cloud and match?

    I have already backed up all the itunes files on two different external drives. And I have already set up icloud and itunes match. I am still paranoid about deleting the files from my MBP, but I need to free the space. What steps should I take to delete the files. And can I still keep itunes (w/o all the music files) on my laptop and access the music from the cloud? I know I can run them with the external drive plugged in, but looking for a way to do it w/o pluggin in.

    I have tried that as well.  The purchased songs are not in my playlists and they are still there.  I manually deleted them on the phone but the sync puts them right back on there.
    I only sync playlists and they aren't on there.

  • Problems after downloading the lastest version of iTunes for my iPod Touch. Now whenever I switch on my laptop and access the internet I get an error message. 2nd time this has happened and I'm fed up trying to fix it. Anybody having similar problems?

    I've downloaded iTunes 10.5 onto my iPod Touch, no problems but I've now got a constant error message on my laptop everytime I switch it on and access the internet. The message is "The procedure entry point xmlTextReaderConstName could not be located in the dynamic link library libxml2.dll"
    This is the 2nd time this has happened. Last time iTunes Support called and we ran through a load of checks to no avail. The only option was to delete iTunes completely off my laptop and go for a new download of it. Can anybody tell me how to do it - didn't write it down last time, silly me, never thought it would happen again. Also sent an email to iTunes Support - waiting for a response.

    Maybe:
    "Waiting for changes to be applied": Apple Support Communities
    Also I requested that your email address be deleted. Personal responses are not given in this forum

    I guess you are trying to connect from the R3/ECC to the Portal Server.
    Are these two systems in the same network? Do you have usernames (valid and fully authorized) in both systems? What is the OS on which these two systems are housed?
    Please provide these details to proceed further.

  • I'm having trouble with iTunes synching and accessing the iTunes store.

    I'm having trouble with iTunes synching and accessing the iTunes store.   When synching, the process tops at the back up stage, freezes and I can't close the iTunes window, need to ctrl alt del.   When trying to access the store, the progress bar stops halfway.   I've googled heaps and tried most of the standard answers - unistall, reinstall, etc, now looking for some help please.
    This has only started a few weeks back, after working smoothly for the 2 years of owning the iPhone 3gs.
    Any suggestions will be appreciated, it's getting realy frustrating.

  • Setup mySQL and access the same from jsp

    Hi,
    I have installed the MySQL in local desktop in d: drive. As per the documentation, have created my.cnf file to point sql directory in d drive.
    Now I dont know how to proceed further. I need to see if MySQL installation is fine, create table and access the data in jsp page. Please advice.
    Thanks in advance.

    For MySQL help try a MySQL forum.
    For connecting to the database, use JDBC. You can get the MySQL JDBC driver from www.mysql.com.
    From there just follow standard java database connection setup.
