Human task expression builder (10.1.3.1 GA)

When I open up the Expression builder while inside the humanTask builder/editer/whatchamacallit I cannot see any BPEL variables. The Title displayed in the Expression builder is schema (vs the BPEL variables I see elsewhere). This gives me access to Task variables which isn't what I want. I want access to BPEL variables to use my dynamic expressions.
In addition to the above the expression builder is essentially broken within the humanTask. <Control><space> doesn't work properly.
This has behaved the same in both the developer preview and GA versions. Tell me that this some stupid configuration parameter that I've got fouled up. I can't deal with it as I'm currently experiencing.

The Expression editor inside of the Human Task editor does not show the BPEL variables as the XPath expressions are not evaluated from the context of a BPEL instance, but are executed in the context of the Human Task instance. This is not a bug.
In order to refer to BPEL variables, one can use input parameters (as noted by John above). You can also map the output parameters from the task to BPEL variables - once the Human Task activity completes.
Please refer to section 15.6.5.2.1 of Oracle® BPEL Process Manager Developer's Guide for details.

Human Task – Using expressions in task parameters

Hi All,
In my BPEL process I have a Human Task with about 15 task parameters. I'm trying to define BPEL variables to each and every parameter. I am able to select a type 'variable' variable (ie. /ns18:OutputParameters/ns18:street_name) from tree view and save.
However, whenever I click on the little flash-light icon and create a type 'expression' using the XPath expression builder I'm having problems saving the change.
In details this is what happens,
0.) Double click on Human Task
1.) Click on flash-light icon in front of a parameter.
2.) Select Type expression variable.
3.) Click XPath expression builder.
4.) Select conversion function 'string()' and double click to add.
5.) Double click on the required BPEL variable to add.
6.) Something similar to the following expression is created,
string(bpws:getVariableData('InvokeGetAllABCInformation_FetchABCInformationService_OutputVariable','OutputParameters','/ns18:OutputParameters/ns18:ACC_ID'))
7.) Click OK twice and then Apply/OK to go back to BPEL diagram view.
8.) Now at this point the BPEL is not saved and the tab-title is italic to show it’s unsaved.
9.) Save the BPEL to disk.
10.) Double click on the Human Task to show parameters and variables defined.
11.) The previously defined expression type variable is still there.
12.) However now if I click either 'Apply' of 'OK' buttons without making any changes the BPEL diagram tab-title becomes italic and when the BPEL is saved to the disk, it forgets about all the expression type variables that was previously defined. Also note that cancelling wouldn't change anything.
This is a serious issue as I can't change any setting to a Human Task parameter list, as every time I make a change, I loose all the expression type variable declarations.
Could this be a bug in JDeveloper?
My JDeveloper Studio Edition Version is: 10.1.3.3.0.4157
Any help on this would be greatly appreciated.
Thanks.
Shaminda.

ok, looks like no one knows what's going on,
Here's the workaround that I came up with, If anyone is interested.
Create a custom XSD (schema) with required variables in it (to be used by expression types vars), and use a copy operation before the human task and create the expression types in there. Then use the schema to map the values to the human task.

Can I build an user Interface using a proccess with Human Task?

Hi,
I'm building an application, web application, with a several screens. The application just will be used for entering some data and depending on the data entered, some bpel process will be launched.
I'm thinking about implementing a MVC using a BPEL Process with Human Task. I mean: I'll make everything with bpel process (*including the application*). I would make a bpel process with some human task. This process would be like a Spring Webflow file or similar. Each screen wouldl be a human task but with synchronus nature. Will it be possible? Will it be so complicated? Is it usual?
Other way would be making a web application to enter data and then launch a proccess that will record the information in the database. That would be the normal way.
Thank you so much.

Hello,
There's a more powerfull solution you may use.
You can create a View. Some Views can be updatable (it means that it's possible to update
the Table from the View) and, you can add constraints (Primay Key) on a View.
For instance:
CREATE OR REPLACE VIEW {color:red}User2.view_name{color}
({color:red}col1{color}, {color:red}col2{color}
UNIQUE RELY DISABLE NOVALIDATE,
CONSTRAINT {color:red}pk_view{color}
PRIMARY KEY {color:red}col1{color}) RELY DISABLE NOVALIDATE
) AS
SELECT {color:red}col1{color},{color:red}col2{color} FROM {color:red}User1.Table1{color};This example is from the link bellow:
[http://www.psoug.org/reference/views.html]
Hope it can help.
Best regards,

Dynamic participant block in Human task flow

Hi All,
I am working on human task flow and got stopped on below use case.
I have two participant block let say A and B. I want to assign participant A depends on flat inside task flow parameter. If Flag is Yes, then it should assign to A and on approval of A it should complete the task flow. But if Flag is NO, then it should first assign to B, on approval from B, it should again assign to A and after that it should complete the task flow.
I tried to use dynamic role assignment but there i am not able to define above use case. Dynamic rule is saying you can assign A or B depends on some rule(task flow parameter) but my requirement is little different.
If Flag is Yes,
- assign to A -> on approval -> complete the task flow.
If Flag is No
- Assign to B -> on approval from B -> assign to A -> on approval from A -> complete the task flow.
I want to build this logic inside single human task flow.
Please help.

Hi Zaloa,
Can you pls try this.This should work.
1. Go to Edit Task Definition page and add a Parameter of type string(default).
2. Now come to the human task dialog( the one you get on double clicking the human task activity) and add a value to the parametr you just added(string)using the search light .This value should be the variable containing the value of the asssigne which you want to add dynamically.
3.Now again go to the Edit Task Definition page and select the Assignment policy and select the expression path builder.
4. You should be able to see the parameter you just added under task:payload. select this . now your assigne is dynamically added.
Pls let me know if you need further details. Hope this helps.
Thnks

Create entity and human task

Hello,
I have a really simple process which includes a create entity activity. It works perfectly fine as data is inserted into the table and i can see everything is completed in the flow trace. Now, when i insert a human task after the create entity activity, things start going wrong. While i don't see any errors in the flow trace and all tasks are completed as planned, the BPEL component's state is showing as running and at the end of the flow i got the message "The transaction was rolled back. The work performed for bpel instance "123456" was rolled back to the previous dehydration point, but the audit trail has been saved...." It seems like it's waiting for something from the human task (even though it was completed successfully). As long as I leave this running, the process would try everyday from 12:00 AM to 4:00 AM every five minutes. That's another issue that i can't figure out. Can someone shed some light on this? Thank you.

Hi,
its best to post this question to the SOA forum. The answer on this forum would be to use a page template, a parametrized bounded task flow and then add the bounded task flow to each page that has the template. However, the task flow in the HT case is generated, which means that you re-build it all the time (meaning you don't work with the same task flow but multiple). If you know how to just use the HT API to access the information to display, you could write a generic bounded task flow for this. Check on the SOA forum if they can come up with a template approach for your use case.

Human tasks, complex types and variable assignment.

Hi folks,
I encountered a problem while working with 10.1.3.1 which I haven't managed to solve yet and would be grateful for assistance. I have defined a complex data type (just a sequence of strings) and want to fill that data type by going through a flow of screens, e.g. through several human tasks. I have defined that type as a variable to the BPEL process and have managed to assign simple expressions to the variable and pass that into a Human Task. In the task I see now a simple input form for all attributes of the type.
Now the problem. After I fill out the form and complete the human task, I have
The global variable:
<outputVariable>
     <part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="payload">
          <MyProcessResponse xmlns="http://xmlns.oracle.com/VacationRequest">
               <vorname/>
               <nachname/>
               <strasse/>
               <nummer/>
               <postleitzahl/>
               <stadt/>
               <maximaleDauer/>
               <minimaleDauer/>
          </MyProcessResponse>
     </part>
</outputVariable>
and the return value from the human task:
<task>
     <title>CaptureData</title>-
          <payload>
               <MyProcessResponse>
                    <vorname>David</vorname>
                    <nachname>Beckham</nachname>
                    <strasse>HighStreet</strasse>
                    <nummer/>

               </MyProcessResponse>
          </payload>
</task>
Now the only thing I would like to do is to replace the original values in the variable with the new values that have been returned from the task, this should be performed in an extra assign step. Sounds simple. JDeveloper wouldn't even let me klick through the return value from the HumanTask, so it seems as if I have to do things manually.
These are my tries:

--> Task does't return (!!!). In the BPEL Worklist, the task is completed, however in the BPEL console it still apears as "waiting to return from Human task".
Does anyone have a hint on how to copy the values so that I get exactly the structure that I printed at the very top?
Thanks for help. Rock On !

Hello everyone,
It seems that we are talking about different things, I am afraid. Let me describe the scenario once again:
- I want to have a BPEL process with more than one role involved
- This process should be used to gather some complex data.
- All data gathering should be done through HumanTasks.
So I defined an xsd complex type, that contains a sequence of fields. This complex type should be part of the process payload.
Now before HumanTask 1 is called, I copy the contents of this variable into the input for tasks1. This works fine and I see the appropriate values, when opening the Human Task in the BPEL worklist application.
Now after HumanTask1 is completed, the values I entered inside that tasks are returned as a variable from the HumanTask. My problem is, that I cannot copy the contents of the task back into the main process. With simpleTypes this is relatively ok, since Jdev supports the assembling of the copy operation, however for complex tasks it fails.
A typical scenario for this would be where e.g. a customer fills a shipping address and afterwards a store staff fills product details in the same order. In Java this could be solved via "pass by reference". Who can provide an example?

BPEL Test waits forever to receive callback from human task service

Hi,
I've created a test (CreditCardInvalidTest.xml) to test a bpel process (testbpel.bpel) which contains a call to a human task service. The problem is when the test executes it waits forever to receive the response message from the human task service but clearly i've emulated it! Would appreciate help.
I've attached both files and highlighted the relevant sections. Thanks.

RaviKiran,
I agree that the explanation oracle provided in the attach link, is a bit confusing. The main goal there is to describe the behavior of processes, when there is a need to combine, or split the transactions within those processes (or in some cases the processes themselves).
The thing is - The default transaction for a synchronous process is requiresNew. That was until version 11.1.1.6. On this last version, you are asking to enter a Transaction parameter when creating a new synchronous bpel process. The default value being prompt is required and that's what causing the problem – You automatically accept the default.
The assumption is, that developing bpel processes, should come with understanding of all those behaviors.
The problem for my understanding is that some of those behaviors were not so cleared until now.

Human Task form data needs to be refreshed in case of abrupt shutdown.

Hi Everyone,
I've got an interesting challenge in my BPM process and was hoping for some guidance.
I'm using the 11g SOA suite. A BPM process within my application is designed such
1. A start node passes a String to a service task
2.The service task makes a call to a webservice operation and passes a payload to a human task
3. The human task has an ADF form built on it and a user can add data to this form in addition to the payload it recd in step 2. When the human task is updated, we have partial submits that invoke webservices to update this data in the database.
Now here's the challenge : If the form is abruptly closed, how do I refresh the data in my form so that it contains the changes made by the user. Do BPM processes auntomatically buffer such data? Or is there way in which I can loop back to the previous step of calling the webservice? All that my form has now is the payload from step 2, I'm resisiting writing a webservice call to refresh data in my form as I can't define what would trigger this webservice call.
Also, another thought I had was that this is a BPM process made of synchronous calls throughout. How can I rectify this so that data is always up to date in the form? Adapters come to mind, but not too sure how. Any guidance is much appreciated.
Many thanks,
Preethi.

Hi,
First thoughts:
I know you say that the data is not in a database, but I think that's the best place for a list like you're describing. Is there a reason why you don't want it in a database?
If it can't be in a database, you could put it in a file and read the file to build your list. That should be pretty easy to do. For changes to the list you maintain the file instead of the hardcoding in the application.

In human task, dynamically assign group doesn't work

Oracle SOA 11.1.1.4
My bpel process invokes a human task.
On the human task Assignment tab, I assigned 3 users (by name), 1 group (by expression).
The group is configured in LDAP
When I tested the bpel process, I entered the group and other data required.
From the worklist app, I see the task listed. It is assigned to the 3 users, but not the dynamically passed-in group.
From the Audit trail, I saw all data I entered (include the group). Everything seems correct, but I still can’t make the dynamically-pass-group work.
If I assign the group by name in human task, it works fine.
The problem is: dynamically assign group doesn't work.
Please kindly advice.

Yes, it is possible assign a group as participant of some human task, passing the group name as parameter.
I have tested just now.
It works pretty well in SOA 11.1.1.4 (BPEL or BPM).
Make sure add a data parameter in your human task definition and pass a valid group name to it.
At the Assignment tab, in the participants' list, add a group, data type by expression, and set the value to the right xpath expression to the corresponding parameter.
For example: /task:task/task:payload/task:group
If it is not working look the SOA log files, probably you'll find some information about the error there. Maybe there is some problem with your jazn.com configuration.
You can also test if there is something wrong related to the group name, trying to transfer some task to the same group by the worklist.

Problem in setting dynamic expiration duration from Human Task

Hi,
I have a BPEL process, in which the Human task expiration has to be set dynamically..
In the , I have set the expiration duration with this :-
<copy>
<from expression="xp20:format-dateTime(xp20:current-dateTime(),'PT1M')"/>
<to variable="initiateTaskInput" part="payload"
query="/taskservice:initiateTask/task:task/task:systemAttributes/task:expirationDuration"/>
</copy>
Do not get confused with 'PT1M' .. I want the duration to be 1 minute... Had I used 'PT1M' as a String and assign to the expirationDuration var, it would have caused an error... It needs to be fromatted as a Date..That's y i took this approach ... I am sure this is working fine as I have checked the payload of the task..
It has a proper duration..
<initiateTaskInput><part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="payload"><initiateTask xmlns="http://xmlns.oracle.com/bpel/workflow/taskService">
<task xmlns="http://xmlns.oracle.com/bpel/workflow/task">
<systemAttributes>
<expirationDuration>PT1M</expirationDuration>
Now in the Human task definition(.task file), I have set the expiration duration with "By Expression" option in this way..
<globalConfiguration>
<owner>oc4jadmin</owner>
<expirationDuration duration="/task:task/task:systemAttributes/task:expirationDuration"
type="XPATH"/>
</globalConfiguration>
The problem is the task(at runtime) cannot evaluate the expirationDuration from the XPATH..
I checked with the WF_TASK table in the orabpel schema ...
When I use a static duration EXPIRATIONDURATION cloumn gets assigned properly (ie PT1M).. But when i take the XPATH approach, it translates to PT0S.
Can someone look into this please ?
Struggling with this for quite sometime...
saptarishi

If the Human Task shows status complete, then it's possible that there was an error in the output data association in the process. In EM do you see a fault on the output for the Human Task activity, or if PS4FP the process will go to suspended state if the data association fails.

Warning after creating Human Task Flow in ADF project

I'm using JDev 11g and have created my SOA Composite containing a Human Task. After I generated the Task flow based on Human Task in my non-soa application, I get the following warnings which are preventing my application from building and deploying to the admin server. I have followed the instructions in the Developer's Guide for Implementing an ADF Task Flow for a Human Task.
Warning: <Feb 22, 2010 9:47:59 AM PST> <Error> <J2EE> <BEA-160187> <weblogic.appc failed to compile your application. Recompile with the -verbose option for more details. Please see the error message(s) below.>

Did I miss a step somewhere, I've double checked the class libraries, but am not sure what I should be looking for, I added the recommended libraries to the class path per the Developer's Guide.

Missing Outcomes for Human Task in Auto-Generated ADF Project

Hi
I am using SOA Suite 11g (11.1.1.5) and have created a Human Task in my composite application and then auto-generated the appropriate task form using the wizard which has been successful and created the ADF project.
My task has 3 outcomes the responses of which are then mapped out in the BPEL process.
When the human task is raised it puts a notification in the BPM worklist as expected however the 'Actions' list on the notification is blank? I was expecting there to be 3 values in the Actions list one for each of my outcomes.
I have tried re-building the ADF project from scratch from the task flow but still no joy.
I have not changed the ADF project over its default.
My next step is to look into the binding on the Actions picklist but I thought this was standard functionality and that the wizard handled this at the point of form generation.
Any assistance greatly appreciated.

Hi
User error.
I had sent the task to a group rather than a user. Before the task outcomes will display in the ADF page a user must first claim the notification using the 'Claim' button. On re-selecting the notification the task outcomes display as buttons.

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.
Regards,
Martien
