How to access task payloads in a taskflow using EL by using pageflowscope

Hi All,
I have a taskflow with task parameter PurchaseOrderBO which has a string attribute named PurchaseOrderId.
What code should I write to access PurchaseOrderId in EL? I think these values are automatically stored in pageflowscope variables.
Regards,
Sam

You have to check the input parameters definitions from the task flow definition file to find out how to refer your input parameters.
For example if the definition is:
<input-parameter-definition id="1">
<name id="2">inputBo</name>
<value id="3">#{pageFlowScope.selectedBo}</value>
<class id="4">myPackage.PurchaseOrderBO</class>
</input-parameter-definition>
and the type of the BO is PurchaseOrderBO, then you will refer your property with pageFlowScope.selectedBo.purchaseOrderId

  • How to access the Text Frame, when we use scrollable frame,

    Hi Friends,
    How to access the Text Frame, when we use scrollable frame,
    Thank you,
    [ Nav ]

    That's the same question:
    how can I access something (a page item) on a page…
    Answer: you need something unique in that object you can get a handle on.
    Or you use the selection a user of your script is doing and work with that selection…
    A "scrollable frame" is nothing special. What it makes it a "scrollable frame" is the DPS software.
    So you have to look for attached labels on the object, that identify the object for the PDS plug-in "Overlay Creator" as a "scrollable frame". That's possible with the "extractLabel("KeyString")" function. But you need to know the appropriate key-string in advance.
    In another of your thread in the DPS forum, I basically answered the question how to obtain those key-strings.
    When knowing the key-string you could loop through all your page items (you can skip all text frames) in the allPageItems-collection, to identify the "scrollable frame" by extracting the right label.
    If you have more than one "scollable frames" you need a second unique identifier for the particular object.
    That could be nearly any property.
    Keep in mind, there is no "scrollableFrames" collection in the DOM !

  • How to access C/C++ functions in Java using existing .dll library

    Hi JNI Guru's,
    I am having well written API in C/C++.This C/C++ files are made into *.dll files.The api are working fine.
    I wan't access the C/C++ api functions in Java., just using System.LoadLibrary("*.dll").Is it possible.I kindly request you to suggest some examples and how to do this.
    Its Urgent !.
    Thanks and Regards,
    V K LAL

    In general you cannot simply access dlls that have already been written. The DLLs called using JNI must conform to JNI calling standards.
    This means you will probably have to write one or more "wrapper" dlls which a) provide the correct JNI interface, and b) call the existing dlls.
    There are some programs around that claim to be able to generate such wrappers. Try a google search for "wrapper", "jni", "generate".
    The JNI tutorial covers creating wrappers.

  • How to access the function in loaded application using swfloader?

    Hi,
    I have a main flex application which has a view stack, panel
    and swfloader in the below hierarchy.
    Flex main app --> Canvas1(Viewstack) --> Panel1 -->
    Swfloader
    Please view
    http://www.probe7.com/flex_ques.gif
    for better understanding.
    I have a function in the loaded application which has to be
    called from a function within the main application. I am not sure
    of the syntax to access the swfloader content which is placed in a
    canvas -> panel.
    I tried this example (
    http://livedocs.adobe.com/flex/3/html/help.html?content=controls_15.html),
    it works when the swfloader is placed in the main application
    without the viewstack or panel. How can I do this, Is there a way
    to access all the running applictaions, regardless of the
    hierarchy? Any help will be greatly appreciated.
    Also any links for quick reference on various components and
    their access will be helpful.
    Thanks for your time.

    You are probably seeing the deferred instantiation behavior
    which is the default for ViewStack.
    The Swfloader component does not exist until a user navigates
    to the View that contains it.
    Use events to determine when the swfloader content is ready
    for interaction. Here is an example:

  • How to access internal photo storage of iPad using Mac

    Hi,

    It is OK when I connect my iPAD to a Windows based PC, I can find out my iPAD in 'My Computer' and access the internal storage.
    But I cannot find out a way to the same on my MacBook Pro.
    Can anybody give me a hint how to delete RAW files in iPAD? Thanks.

  • How to access SMP if I don't use SAP product but only MaxDB?

    Hi All,
    I am sorry if this is answered elsewhere, I am a MaxDB user and our company operates a website with MaxDB as the data engine behind it since 2003. Recently I am evaluating if we can use synchronization to scale out, however I hit road blocks when I research information and most are on SMP which requires a login. How can I get access there ?
    Regards,
    Chris

    Hi Chris,
    the SAP Service Marketplace is for SAP customers only.
    Anyhow, especially for MaxDB there are many information available for public use.
    There's the [WIKI|https://www.sdn.sap.com/irj/scn/wiki?path=/display/maxdb/main] and the [MaxDB Website|http://maxdb.sap.com/] that includes online searchable documentation, as well as trainings materials and presentations from the MaxDB events.
    A good starting point is always the [MaxDB Homepage here in SDN|https://www.sdn.sap.com/irj/sdn/maxdb].
    If you don't find your questions answered with these options, you can always post your question here to the forum.
    Anyhow, what information did you want to look up and only find them in the SAP notes on SMP?
    Especially if you're an "Open Source"-MaxDB user, most of the available documentation is already made accessible via the resources I mentioned.
    regards,

  • How to send the payload to a jsp using receiver Http adapter?

    Hi experts,
    I have this scenario from Legacy to XI to external app server.I have a test jsp to execute that functionality .Its a jsp which has 1 textarea named "test" and when I click on the submit buton I get a response back.This way I am able to test this independently.Now from XI when I am executing my scenario I am getting status code '1250' and message as ' http request(test) is null'.Now in the scenario in http adapter I just provide the target host : ip of server ,
    service number : port no ,
    path: the container or the request handler. But this scenario fails and gives me the above erroneous response.Now Basically I am not able to get how to send the value to the textarea "test"? please provide help as soon as possible.Do we have to put the name of the jsp in the "path" in http adapter and use prolog as test=.I tried this but it doesnt work.
    Is there any way to check the URL that it forms after appending the querystring in the url ...?
    So please provide help on this or suggest a solution to [email protected] as soon as possible.....
    Thanx in advance.
    Akshata

    hey Shekhar,
    thanx for that prompt reply but I have configured the communication channel in the same manner as suggested by u.
    actually I have this jsp page http://xx.xx.xx.xx:8080/abcdef/try/efg.jsp where there is a textarea "test" which has to be filled and there is a submit button.When I test this http client i.e the above jsp page independently then it goes to handler
    http://xx.xx.xx.xx:8080/abcdef/trial/    And it gives a proper response message after clicking on the submit button.
    now I want to carry out the same using receiver http adapter. I need to pass the value for this inputfield names "test" on that jsp . so right now I have configyured the adapter as
    addressing type: url
    target host : xx.xx.xx.xx
    service no:8080
    path : here I have given the path of handler i.e /abcdef/trial I tried giving the jsp page also but logically I guess it should be the handler.
    content type: text/xml; charset=iso-8859-1
    xml code: UTF-8
    Mask special characters (URL escaping) checked.
    now since the name of the inputfield is "test" in the prolog I gave test=
    But it doesnt work I get this error "http request parameter [test] is null" in the response message  which I guess suggests that it is not able to send the value for the field"test" to that handler.Please suggest how to send this and tell me if there are any other configurations that I have to do in the receiver communication channel.
    Thanx ,
    Akshata

  • How to access the attributes in an object using TestStand.?

    hi,
    I have a class named Status in C# that has 2 data members. There is another Class named Parameter and it has functions that return objects of type Status.
    I made the DLL of the class Parameter. Then i added that class to NI TestStand and called a fucntion and that function is returning an object of type Status.
    Is there any way by which i can access the Data Members of the returned Object in TestStand ??
    Thanx in advance
    Solved!
    Go to Solution.

    Yes, there is another alternative. If you make Status a value type (i.e. a struct in C#) then you can tell teststand to store it in a corresponding TestStand data structure rather than an object reference variable. This works even for private fields in your struct. To do this:
    1) First make Status a value type and make whatever other changes are necessary in your code to account for this (value types are copied when passed by value to another method, if this is not what you want you will need to pass them by reference - i.e. ref keyword in C#).
    2) Recompile your assembly.
    3) In the TestStand .NET module specification panel you should now see a new button next to the expression for the return value of type Status that looks like the TestStand data type icon. Push that button and it will prompt you to create a TestStand custom data type that corresponds to the .NET type. Select to save the type in MyTypes.ini type palette file. You only need to do this once. Once the type is in your MyTypes.ini type palette file it will be available from then on and you only need to update it if you change the .NET type.
    4) Create a local variable of the TestStand Custom data type instead of Object Reference. Note that you can expand it and see the properties underneath.
    5) Use this new local variable to store the Status return value. TestStand will copy/update the properties of the variable to correspond to those of the .NET struct that the method returns.
    NOTE: You can also just store the individual fields of a struct in separate variables by expanding the return value of type Status once it's a struct and specifying a separate variable for each field rather than creating a TestStand custom data type.
    Keep in mind that TestStand is making a copy when you store a struct this way so changes to the struct after this will not be reflected in the copy.
    Hope this helps,

  • How to filter tasks on the Creation date using the IWorklist API in Java

    Hi all,
    I'm currently developing a java gui application to display usertasks set by the BPM.
    I use the WorkList API to communicate with the TaskActionActionHandler.
    I only want the tasks that has a creation that is after a specified date. Therefore I add a filter. The code for retrieving the usertasks now becomes:
    Map filterMap = new HashMap();
    SimpleDateFormat d = new SimpleDateFormat("dd-mm-yyyy");
    Date date = d.parse((String) dForm.get("filterdate"));
    Calendar cal = Calendar.getInstance();
    cal.setTime(date);
    filterMap.put(IWorklistService.FILTER_TYPE_CREATE_DATE_FROM_FILTER,
    cal);
    RemoteWorklistServiceClient client = new RemoteWorklistServiceClient();
    client.init();
    IWorklistContext ctx = client.authenticateUser(user, password);
    List tasks = client.getWorklistTasks(ctx, filterMap,
    IWorklistService.SORT_FIELD_TASK_TITLE,
    IWorklistService.SORT_ORDER_ASCENDING);
    You can see from the above code-fragment that I specify a FILTER_TYPE_CREATE_DATE_FROM_FILTER filter that is given a Calendar object. This is not working properly. Also a Date value gives a runtime error.
    The error I get is :
    ORABPEL-10150 Worklist Service Task List Error. An error occured in the Worklist Service while retrieving the task list for user jcooper. Check the task filter criterion and the error stack and fix the cause of the error. Contact oracle support if error is not fixable. at com.evermind.server.rmi.RMIConnection.EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER(RMIConnection.java:1602) at com.evermind.server.rmi.RMIConnection.invokeMethod(RMIConnection.java:1553) at
    Can anyone tell me what kind of dateformat I have to specify for the filter option FILTER_TYPE_CREATE_DATE_FROM_FILTER?
    Thanks in advance!
