Issue with Task Control Call back and Event Choice in WLI BPM 8.1

Hi,
I am using a Task Control Factory to create Task Control Instances in a loop
and then
create tasks and assign them to a predefined group. I have an event choice
for two events
waiting for the onTaskCompleted and onTaskAborted event call backs.
I have two such operations (of task creation) in the same loop. For
simplicity I have used two separate task factory controls for each of the
tasks (because I even had worse problems using a single control factory for
both tasks in the same loop).
When I instantiate the process, through work list I am able to claim, start
and complete the first task. When I try the same procedure (claim, start and
complete) on the second task, the the event choice for the corresponding
task receives 2 event call backs. First it receives the onTaskCompleted as
expected, but then it also received another call back of the same type which
displays the error on the server log as:
<Sep 24, 2003 9:43:56 AM EDT> <Warning> <WLW> <000000> <on process
completion, 1 undelivered messages to

Does anybody know why two events are fired for the same work list action?
Thanks in advance.

  • Having an issue with Parental Controls...

    Hi, I'm having an issue with Parentel Controls.
    I run several student labs set with parental controls on the systems for a higher education facility. We don't have restricted access to web content (our students need to look up a lot of things, even some that would be considered racey, it's an arts school) and when I set it to "Allow Unrestricted Access" to web content, about a week or so later I'll start getting reports that content is being blocked. I go to check, and sure enough the controls are set to "restrict access to content".
    I've had two interations of this issue thus far and it's a pane to go through each system (there are a lot of systems) and manually reconfigure them back to default.
    Any tips?

    My son could not interact with sites (log in, post) but he could access them (when parental controls were turned on). I had to go under "preferences" on Firefox (under his name) First go to the drop down the menu from the word "Firefox" then "Preferences" "Privacy" (at the top) then "Exceptions" on the right..... and add each address of the sites and pages I wanted to allow. That worked like a charm!! Maybe pull up the itunes STORE address, copy and paste it in "always allow" (you can choose "block" also.....) This is in Firefox PREFERENCES, not just the parental control section.....
    Let us know if that helped! Apple was NO help. (I am an Apple fan, but I am not paying 49.99 to get a question answered by someone who didn't sound like he knew anything, anyway...) I think when you pay for a computer you deserve to have ALL the features work... Is that too much to ask?

  • OSX 10.9.1 Compatibility issue with Sharp Aquos PN-L702B and PN-L802B

    I have Mac Mini's connected to the Sharp Aquos PN-L702B and PN-L802B touch screens and after updating to 10.9.1 am experiencing what appears to be a compatibility issue with the Sharp TPM driver and the OSX 10.9.1.  
    Everything works perfectly previously on 10.8.4 and 10.8.5.  I did not test on 10.9.0 as I went straight to 10.9.1.  Anyone else having this problem?  Any thoughts on resolution?

    OK so perserverance seems to have helped here - i used the cmd R function on start up to get to the page where i can re install OS X Lion - Safari now working.
    However i have Office 2011 for MAC and now Excel wont start so i will post on another thread for help with this
    Hope this helps if anyone has a similar issue

  • Issue with Acrobat 10.1.2 and Windows 7 64-bit Preview Handler

    Hi. I work in an enterprise environment that is currently migrating to  64-bit Windows 7. The only version of Acrobat we have approved for Windows 7 is 10.1.2. We're seeing an issue with this version that causes the preview handler to not work. The preview panel in Explorer is just white and will eventually give the error "Preview handler surrogate host has stopped working."  I've tried to fix listed on http://www.pretentiousname.com/adobe_pdf_x64_fix/index.html but that registry key is already correct. Our current work around for these users to just install Reader X1 and make it the default PDF handler, but I would like to find a better solution. Is there a known issue with Acrobat 10.1.2 and 64-bit operating systems? Or is there a way to change just the default preview handler?

    Most of the info on the web page you link to is 2-4 years old. I doubt it applies. Your workaround is actually the best solution: It's always preferred to use the latest PDF viewer. Reader and Acrobat can exist on the same machine.
    Also, why 10.1.2? There have been 6 releases since then with documented security enhancements (meaning there are also published vulnerabilities which are patched), bug fixesm, and feature enhancments.
    I'll ping some folks about the error you are getting. . .

  • Problem with the browse sequence back and browse sequence next widget placed in the screen layout

    Hi,
    Some basics: We are using Robohelp 10 to  generate multiscreen  html5 output. We used the pharmaceutical  screen layout downloaded from:  http://helpx.adobe.com/robohelp/robohelp-screen-profiles-layouts.html but modified it to match our GUI.
    We are having a problem with the browse sequence back and browse sequence next buttons placed in the screen layout from the widgets tool bar. We are in no way experts at this part of Robohelp...and the css portion of all this is a bit of mystery but we have managed to get mostly what we need. Now we just need these buttons to work. In the past we used Airhelp and things worked great. Can anyone help us understand why the sequence buttons are not showing up in the output even though it does in the topic preview?
    Also
    This shows up in the  layout.css file:
    a.wBSBackButton {
                    margin: 0 8pt 0 0;
                    padding: 0;
                    background-color: transparent;
    img.wBSBackButton {
                    border: none;
    a.wBSNextButton {
                    margin: 0 8pt 0 0;
                    padding: 0;
                    background-color: transparent;
    img.wBSNextButton {
                    border: none;
    Also btw, I forgot to mention that we are linking our FrameMaker files.
    Appreciate the help.
    Thanks!

    Are there ANY compatibility issues with Itunes 12.0.1 and Mavericks?  Don't want to download Yosemite.  Not hearing good things about it.  I'm on Mavericks 10.9.5.

    one obstacle, quickly removed. thank you.
    nomenclature aside for a moment, 10.6.8 is correct but maybe more is necessary about the MacBook Pro: it is 'old': Identifier: 1.2, Intel Core Duo, 2.16 GHz, 1 Processor, L2 2 MB, RAM 2 GB.
    i hope that is enough to get an answer to this: is it unadvisable to update its OS; in other words, if i update to 10.9, will the machine be able to handle it, 'speedwise'?

    How to integrate Oracle Right Now with our application Calling Button and Chat Button. Application is on WebCenter  Sites

    Thanks handar. As per your instructions I have tried OAM authorization policy and its working fine. But we also wants to check the same with OES also. Currently I have configure weblogic SM and created domain. In same domain I have deployed my application also. I have created application, resources and authorization policy to authorize /myfolder/index.jsp if user has some specific role. Now if I try to access my web application using http://host:8001/CONTEXT/myfolder/index.jsp, it doesn't check if user is authorized or not. I guess my application is not related to the resource I have created. Please help me with this. Also, let me know if we can retirive logged in user from session and use for authorization.

  • Issue with Visibility Settings for Backgrounds and Layers

    I am using Acrobat Pro XI 11.0.10 (Windows) and having an issue with visibility settings for layers and backgrounds. I am attempting to get backgrounds to appear while viewing in Adobe Reader and Acrobat Pro but not be printed and so far have had no success.
    When using a background the Appearance Options dialogue has "Show when printing" unchecked, but "Show when displaying on screen" is checked. This results in the background not showing on the screen, and the background will only appear once the box for "Show when printing" is checked. It looks like the option for printing is dictating whether or not the background is able to appear.
    Using layers has not worked either. The background layer is set to "Never Prints", but will still show up when printed.
    I was wondering if anyone else has run into this and has a solution, or has any recommendations.
    Thanks in advance.

    Hi setrev2012,
    How are you adding the backgroud?
    The only way I can think to accomplish this is via a watermark.
    The basics...
    Open PDF in Acrobat. Choose Pages > Watermark > Add Watermark.
    Select a jpg or PDF of your background and adjust scaling options as desired.
    Then click the Appearance Options.. and uncheck the Show When Printing option.
    In this image the PDF is a blank page with the word "Test" on it. The watermark is the stamp and impression (a stock photo jpg).
    If you want a solid color background, just create a flat image of the background color for use as the watermark.
    If you have already followed the steps and still facing the issue then please share the file with me at [email protected] so that i can have a look.

    Rave

  • Human task flow call back events with external web service

    Hi All,
    I have a requirement to call webservice inside human task flow. I have three participant in my human task flow. Let suppose A, B and C. When A approves then task will be assigned to B and when B approves it will go for C.
    My requirement is that, when A approves , then i need to call one external webservice to update database. For this i have enabled call back events from human task flow.
    In this way i got while loop inside my BPEL. In onTaskAssigned operation i am now trying to call external web service. My requriment is to call external service and get data from service. After getting response from the webservice, i want to assign it to next participant.
    But in this case, when user B approves, it goes to onTaskAssigned block and i am able to make external web service also but mean time, it has been assigned to User C which i do not want.
    I want Human task flow to wait for the web service response then only assign it to next participant.
    Please help.
    Regards,
    Sunil

    Hi Sunil
    Have you tried using WebServices Adapter. The usecase seems pretty straight forward. You have a WebService that has some code and some Operations to update some Database. First thing, I hope you have methods/Operations defined with request and response xsd for each operation.
    Now you define the main master payload, that should have all elements specific to your process and also few elements to store the output coming from each operation. Because response of each operation may need to go to other Task and get saved in the Payload also.
    You have like 3 Tasks. To complicate, I will assume that each Task can either Approve or Reject. And last 2 Tasks gets data from payload, previous task and also output from the WebService Operation (method).
    Task A -> Xor Gateway (Approve/Reject) -> If Approve -> Call WebServices Adapter -> Task B -> Xor Gateway(...) -> ......
    At each intersection, you can map the attributes for incoming and outgoing. Based on WebServices output also, you can have Another XOR Gateway and decide to send to Task B or do something else. So combinations of outputs of each service (task or webservice adapter) and XOR gateways, you can have a decent control on the overall flow.
    Note: I am hoping the webservices is Synchronous where you get the response immediately.
    Let me know if I am missing something.
    Thanks
