Task Controls in Worklist

Hi all,
I have used the Worklist component in my jspx page, and am able to view the task (created through my Human Task in BPEL) in the page. Now, i want some control buttons in my jspx page where in i can either accept or reject the task.
How can i achieve this?
By default, I get a link "Details" under my task which links to the BPM Worklist (integration/worklistapp) page. I dont want something like this.

guys....some help pls.

Worklist - Task Control Factory Event Handler Issue

I am developing a worklist application, which requires to create Task (Approval Process) for each user in a group.I have created a Task Control Factory in a "For Each" loop which creates multiple Tasks and i can see them through the default "worklist GUI" provided also "complete" the tasks. The Issue is the "onTaskCompleted" event does not get captured. It just gets lost.
FYI, I have followed the BEA guidelines (http://e-docs.bea.com/wli/docs81/worklist/advanced.html#1076366)for creating Task Control Factories.
Any kind of help will be really appreciated

I am only guessing here, but since your process is creating multiple tasks, the completion of any single task can't be captured by your process. Once you start creating multiple tasks your ability to monitor a single task probably gets lost.
One possibility to fix this is for your process to have a parallel branch: one branch will call a sub process for each task that you need completed and one branch will receive the call backs from the sub process. In this way you will be able to have multiple tasks created simultaneously while still capturing the individual onTaskCompleted events.
Hope this helps.

Customization of Human tasks the BPM Worklist App with ADF App

Hi All,
We are building a custom ADF application which aims to combine several business process human tasks to a unified interface.
And how to integrate the Human Task Flow BPM Worklist to my ADF App.
Otherthan that
To the BPM Worklist App we want to do customizations also like
1.Want to customize to apply our own custom skins to customize banner logo, title to the BPM Human Task Flow App.......
2.And based on the logged in user/role we wanted to restrict the features of the Work List App.
Say for Example should not provide the Facility to Add New Page if the logged in user is not an Admin, like wise no provision to add or modify or delete the Worklist Views like that...
How to get control the App based on User/Role
Any help or pointers would be appreciated!
I have ADF Experience from projects Using JDeveloper 11.1.1.5.
But, for me this is the first BPM case.
Renuka

Hi Renuka,
There are basically two ways to create an ADF UI for a BPM Task:
1. Generate it from the task
2. Create a ADF Taskflow based on Human Workflow Task
Since I tell this by heart, I might be slightly wrong in the terms.
You probably want to try the second option. It is accessible from the "New Gallery". You'll have to provide the Human Task from the BPM project, but then you can build up the ADF Taskflow by your self, based on the customizations of the rest of your application.
Should not be rocket science for someone with ADF11g experience. Since it is not my dayly job, I need to figure it out every time again ;). But I did it in the past and it wasn't so hard.

Cannot open GP process task in universal worklist.

Hi all,
    I cannot open GP process task in universal worklist.It says:"Could not retrieve process instance: contact your system administrator".But i can open the task in Runtime task.
i configure the universal worklist by following this link:
http://help.sap.com/saphelp_nw04s/helpdata/en/43/ef06a7860c7061e10000000a1553f6/frameset.htm
I also create a simple GuidedProceduresConnector and doesn't change the xml file,but it doesn't work,either.
our portal is SP11.
Can anyone help me?
Thank you~!
Best regards
delma

Hello Delma,
Check out SAP note 1104652.    It discusses some changes for the uwl configuration file.   I just did this on a local installation of CE and used the following XML for my GP actions. I just uploaded a paper on this - it should be on SDN within a couple of days and I can get you the link.
The trick is that the name of your GP alias in UWL administration must be included in the XML. The note explains this and there is an example to download. Also, in my example the iView for the portal content to start the GP had to be changed - but that could be due to my local installation.
Check out this note and this XML and let me know if it helps.
Best regards
Ginger

Adding custom properties to a human task of a worklist

How can I add custom properties to a human task of a worklist. I don't know if it is possible. I tried to read the oracle BPEL Process Manager Workflow Services API Reference, but this is unreadable :-). Classes, Methods and Parameters are not commented...
Moreover where can I find a GOOD description of the Workflow Services API explaining the usage of the classes, methods and their associated parameters ?
Regards. Yvan

I means I would like to add some parameters to the task without having to load the payload. I would like for example to use these parameters to do query on worklist. Or may be there is also a mean to do search query on worklist using some values that are into the payload of the tasks. May be you can help me :-)
Regarding the documentation of the worklist API, it is for me very difficult to understant the role of the method as for example SystemMessageAttributesType.setTextAttribute1() or SystemMessageAttributesType.setNumberAttribute1() and so on, if there is no javadoc available and it is the same thing for all methods of the API :-).
Definitivly I would like to understand the Task entities and all available properties and action I can apply to it to know excatly what I can do with it. Where can I find this information ?

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

One task control multiple DAQ modules

Is it possible to have one task control 2 or 3 DAQ modules? I do not seem to have luck in doing so.
Also, for a digital output NI device that sources voltage, if I hook up 10v to it and the module has 10 channels, how on earth are the 10 channels each able to source 10V, when I only supply one 10v power supply.
Does it just send extremely small amounts of current per channel versus sending a decent amount of current per channel if I just had one output on?

Hey all,
This is a crosspost, I posted somewhere else after posting this post, just because I did not know whether I posted in the right place, here is the link to the other in case anyone else comes across this problem: http://forums.ni.com/t5/Multifunction-DAQ/one-task-control-multiple-DAQ-modules/td-p/3170766 Sorry about that.
Anyways, I have
NI 9401,
NI 9403,
NI 9474,
NI 9375,
I am using a
NI cDAQ-9184 chassis
I believe these are all compactDAQ.
I would like to combine the 9401 and 9403 into 1 task, and the 9474 and 9375 into 1 task.
Also, I am having issues with one of the modules, the 9375. When I wire False data to the Write DAQ on LabVIEW it seems that the 9375 is still sourcing some voltage. I cannot remember the difference in voltage of then I wire true data versus false, But I believe they were somewhat close. Has anyone came across a problem like such?

More flexible task control

Currently we have wery limpted task control options: to see executed task percentage and to stop it.
What about some kind of priority management and ability to pause or even schedule some tasks instead of stopping them?
The main reason for my suggestion is this: often I started, say, exporting a lots of tiffs, but suddenly I need full proccessing power for some particular task. I wish to pause LR, not to stop completely and then try to remember where I was.
The second reason: some exporting tasks are actually not so urgent and better to give them low priority. Lightroom is not a speed daemon, unfortunately.

+1 vote.
At a minimum:
- Having long running tasks execute at low priority.
- Pause/Continue.
I dont know how hard the first item would be given Lightroom's design, but the second one cant be that hard...
PS - I used to start Lightroom itself at low priority so I could play HD video (without stuttering) while exporting, but since I upgraded my motherboard this is no longer a problem. Anyway, a work-around is to change priority of Lightroom itself... One of my biggest reasons for pause/continue is to process a new batch of photos without having to restart an export...

How to modify a part of task parameters via worklist (not all paramenters)?

I am making a demo of showing the functions of human workflow / worklist using Oracle SOA Suite. The following process is not a real project. But I have some questions about how to modify parameters in worklist and jdeveloper. Please help me.
I create a BPEL with human workflow. It has 2 human tasks.
The first human task is a single approver type and the parameters contents can be modified via worklist. The user is oc4jadmin.
If oc4jadmin rejects it, the process will go to the second human task.
The second human task is a sequential lists of approvers type and the parameters contents can be modified via worklist. 3 users (the order is : jcooper -> jlondon-> tolstoy) can access it. The process is able to abrupt completion if anyone rejects it.
After the process is invoked in BPEL control,
1, oc4jadmin login worklist and modified the data, than reject it.
2, jcooper can login worklist and changed the data, save it, and approve.
3, jlondon login, view data, change data, and save it. However, if jlondon modified the
My questions are as follow:
1, If oc4jadmin rejects the task in worklist, how can I set the parameter cannot be modified and saved.
2, schema:
<schema attributeFormDefault="unqualified"
     elementFormDefault="qualified"
     targetNamespace="http://xmlns.oracle.com/BPEL_single_sequential"
     xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:vv="http://xmlns.oracle.com/BPEL_single_sequential">
     <element name="BPEL_single_sequentialProcessRequest">
          <complexType>
               <sequence>
                    <element name="input" type="vv:complexType1" maxOccurs="unbounded"/>
               </sequence>
          </complexType>
     </element>
     <element name="BPEL_single_sequentialProcessResponse">
          <complexType>
               <sequence>
                    <element name="result" type="string"/>
               </sequence>
          </complexType>
     </element>
<complexType name="complexType1">
<sequence>
<element name="pid" type="string"/>
<element name="ptitle" type="string" maxOccurs="unbounded"/>
</sequence>
</complexType>
</schema>
In the worklist, the user can add another pid and leave the ptitle empty. In the schema, the ptitle (minOccurs=1) should appear at least once. How can I set that, if the user add another pid and must add at least one ptitle before saving it?
3, One element likes gender=male/female. In the worklist form, the default graphic component is an input field. How can I set the component to a dropdown list and it highlight value.
4, The default form is jsp file and it is beautiful. Could I make a jspx page and replace the jsp page? How to replace the jsp to jspx?
5, If I use sequencial approver type for the human task, how can I set various page layout? For example, user 1 can view and modified all parameters. User 2 can view some part of the parameters and changes it. User 3 can view all paramters but can just modified some of them?
Thanks a lot!

Hi,
all what you asked about can be done through java script.

BPEL control and Worklist Application cannot run after adding new realm

I using command line to add new realm, roles, and users in JAZN.
Then, I change the default system-jazn-data.xml (BPEL---should be BPEL or BPM, cannot remember, HW) to the new one.
Then, stop and restart soa suite.
In the applicaiton server control, I cannot find the BPEL and HW. I cannot start the Worklist Application, and bpel Control. It shows cannot find page.
In jDeveloper, when I create a human task, it shows BPMIdentityServer error and the realm is emply.
How to return to the default realm? Should I reinstall again?
Thank you.

Hi Pucha,
In the file system-jazn-data.xml, I can find the new realm added by me.
I reset the new realm to orabpel / hw_services / ruleauthor / ccore/ .......
Then, I restart the server, create new AS and IS connection.
However, I still cannot find the new realm name in the dropdown list of Human task in Jdeveloper.
How to find the new realm in Jdeveloper? Did I miss something?
I also create a new instance, new realm, new roles, new users, new AS connection, and IS connection. But I still cannot find the new realm in the dropdown list in the human task of Jdeveloper.
Thanks.

How to approve the request only for one time for human task in BPM Worklist

Hi All,
I'm having a requirement where i have made the hierarchy in the .task file where in created two users for which i need an approval in a hierarchical manner. But when i'm approving the request from worklist app for one user and the request is going sucessfully to the second user and if i approve it over there it once again coming to first user where i have approve it once again to get the request processed. how to get request processed only for one time when it is approved. Do we need to customize anything
If you did it can anybody can share thoughts on this please. Your help is highly appreciated.
I am not able to see the rejected request at all. where to see the rejected request.
Regards,
CH

Hi,
Following are the some important points you should understand about ESS Leave Request Workflow
1. The Visualization ( how should it appear in UWL and what should happen when you click on a particular workitem) is defined in SWFVISU. Check for TS12300097. Generally, it invokes com.sap.xss.hr.lea.appl/LeaveRequestApprover Java WebDynpro application. Just check whether you are able to get the correct Leave Processing application called when you execute your workitem from UWL?
2. In general it should have option to process the leave request either approve/reject. When the leave request gets approved/rejected the status of the Leave Request document gets changed ( in workflow it is &REQ.STATUS&
3. There is a need to schedule a background job for program RPTARQPOST which will pick up all the documents in APPROVED status and creates an absence record for the same.
4. Apart from schedule job as mentioned above, you also have to schedule a background job for program RPTARQEMAIL, which is basically used to send e-mails for all the documents which are yet to be approved to correct manager.
as you say , you can not see Approve/Reject options from UWL, it looks to me that correct javawebdynpro application is not being called for this task. Just check this !!
Good Luck !!

Task details in Worklist did not work

I have created a simple BPEL process which use human task flow for approval purposes. The input for the process is initiated from a DBAdapter(poll). For any changes or new row in the database, it will create a new instance.The problem is the task details for the worklist did not show the data retrieve from the DBAdapter. It only shows the table header. There are no error during the deployment and that made me wonder on how to display the details.Any help would highly be appreciated.

the way to display the details is by creating a a new xml schema. Then assign the values from the DBAdapter to the new schema.By doing this, my task details actually displaying the details that I required
