HI , I am new to jbpm, some one plz help me for the bwlow error .

java.lang.NullPointerException

)

Please help me .. thanks in advance..

[swiderski.maciej]

most likely there is a gateway but there is no condition set on its outgoing sequence flows and thus NPE. Anyway I'd recommend to upgrade to latest version of jbpm 6

[swathi123]

Thanks  a lot maciej!!!    Its working!!

As I have mentiond condition for one sequeceflow, i forgot to mention it for another sequenceflow.

But i have one doubt.. if i mention one condition for one sequenceflow, by default another sequenceflow should be true or false based on first condition rite.?

Please correct me if i am wrong.

[swiderski.maciej]

not really, gateways can have as many outgoing sequence flows as you like so you must specify condition on each of them.

Thanks Maciej !!

I am using JBPM 5.4. Trying to understand how use userTask Entity. Could you plz explain about UserTask entity. I want to verify the Username and pwd credentials using UserTask.

1) I am not abel to understand the I/O Parameters section

2) What is the difference between Localvariable list under "EditUserTask" and Properties(DataItems-> Local variable list for process)

I m getting the errror : Please find the attached file

Thanks in Advance!!

Hi Swathi,

It seems like you have two bpmn elements having same id in xml file. To resolve the issue you need to select the check box and click ok. It will generate an unique id for the duplicate element.

jbpm 'Human Task' will be triggered by an actor / group associated with that Human Task node. If you assign an actor to the Human Task then the task will be automatically claimed to that user. User have to start the task & complete with the Map of output variable's key value pair. If you assign a human task to a group, then all the potential users within that group can see that human task. If one of them claim that task, then he will be able to start & complete the task.

Input variables of a Human task are generally populated from Process variables at the time when you start the task, the practical usecase of that is, to fill your UI form field values as pre-populated.

Output variables of a Human Task needs to be supplied as a result map when you are completing the Task and they will be copied to process variables to reuse those values in other Human Tasks.

Hope that will help you.

Regards,

Thanks Soumya!!

I have checked that particular checkbox and tried. but still I can see some errors in XML file like "Data input is missing/Incomplete data type"

I am trying to run the application in console(Using testcase).

As I am very new to this could you please suggest me some Usertask example sites which will help me to understand it in a better way.

[soumya.plavaga]

Hi Swathi,

Can you please attach your bpmn file? I can see and advise then. You can get the sample bpmn files for Human Tasks in jbpm site itself.

Hi Swathi,

There was few issues in your bpmn file. I have fixed them and attaching you the latest one. Please once go through it. Just diff with your version and understand the change I have done.

Note:

- For Data types do not use Drools data types instead use java data types in your process. Example, For String data type do not use 'StringDataType' instead use 'java.lang.String'.

- A script task can not have a multiple incoming / outgoing connection.

Regards,

./sb
