    Jboss AS 7 & JBPM 5.2 --> JBPM Console Error when viewing task forms

    krish t Newbie

      Hi,

       

      I am facing problems when testing evaluation module bundled in jbpm-5.2.0.Final-installer-full.

       

      I am using designer-2.0-jboss7.war available at

       

      http://sourceforge.net/projects/jbpm/files/designer/designer-2.0/

       

      Could someone help me?? Thanks

       

      steps:

      1. Login to Jbpm-console as krisv.

      2. Start the process

      3. Go to Personal Tasks

      4. Select evaluation task.

      5. Click View.

       

       

       

      Now it shows a page with 500 error and below exception:

          Tihomir Surdilovic Master

          Sorry you have to be a little more specific, for instance:

          4. Select evaluation task --> Is this the Evaluation task that is read from the file system (https://github.com/droolsjbpm/jbpm/tree/master/jbpm-installer/sample/evaluation/src/main/resources) or is this a task that you created in Guvnor via Designer? If this is a custom process you created with Designer, have you generated the task forms via designer too?

          Not much we can do unless you show your bpmn2 and your generated task forms so we can try to reproduce.

            Hi,

             

            Thanks for the reply. I am using the sample evalution provided in the (https://github.com/droolsjbpm/jbpm/tree/master/jbpm-installer/sample/evaluation/src/main/resources) . I have attached task forms generated in guvnor and screenshots of execution in my local.

             

            Also,i checked the screencast for jbpm console again and see that varibale 'content' is missing in InstanceData section in my local. This is autogenerated one and I haven't done any changes in the bpmn file.

              Maciej Swiderski Master

              Seems like the issue is that content variable is not set. When you look at the exception:

              freemarker.core.InvalidReferenceException: Expression reason is undefined on line

              it refers to the reason expression that should be inside content variable and content should be set as variable when self evaluation user task is created (with onEntry-script). Could you take a look at server log if there are any exceptions when process enters self evaluation user task?

                Hi,

                 

                I tried to clean jboss(deleting repository,tmp) and restart the complete process. Now the sample evaluation process itself is not showing up any more in jbpm console. And following error is coming up in server logs whenever i click refresh in process view. I have to fix this now to proceed any further.

                • 5. Re: Jboss AS 7 & JBPM 5.2 --> JBPM Console Error when viewing task forms
                  Tihomir Surdilovic Master

                  The error most likely means that you did not build all packages in Guvnor before accessing the the process view in the console. Also you say you have generated the forms with the Designer, but the screen shots you attached are  from https://github.com/droolsjbpm/jbpm/tree/master/jbpm-gwt/jbpm-gwt-form/src/main/resources, so you must have uploaded them to Guvnor manually?

                  Would be nice if you could step-by-step describe your setup so someone can try to reproduce.

                    krish t Newbie

                    Hi,

                     

                    Forms are same as i am testing evaluation process given in installer. I have removed the earlier installation now and started a fresh setup. Here are the steps followed.

                     

                    1. Extract the full installer jbpm-5.2.0.Final-installer-full.

                    2. Run ant install.demo.noeclipse (I already have helios in my local)

                    3. Run ant start.h2

                    4. Start jboss standalone instance directly. I am not using ant start.jboss script to start jboss.

                    5. Run ant start.human.task

                    6. Deploy Evaluation.bpmn(provided under jbpm-installer\sample\evaluation\src\main\resources) to Guvnor repository.

                    7. open http://localhost:8080/drools-guvnor/. Check the availability of evaluation process.

                    8. Use the option in process editor to generate human task forms. It generates two forms(please check screenshot with assets).

                    Note: I get below error when click on the second view source link(highlighted in screenshot)

                    XML Parsing Error: no element found

                    Location: http://localhost:8080/drools-guvnor/rest/packages/defaultPackage/assets/Performance%20Evaluation-taskform/source

                    Line Number 1, Column 1:

                    9. Now build default package.

                    10. Login Jbpm console with krisv user id. Refresh process view. No process are shown here.

                    Please suggest if I am missing something here.

                      jaidev Newbie

                      I have a similar issue. I installed jbpm on a linux server with Jboss AS 7 and made ip changes in jbpm.console.properties. I can see the Process and start them but no tasks are being loaded. Please suggest if I have missed anything.

                       

                      Thanks.

                      • 8. Re: Jboss AS 7 & JBPM 5.2 --> JBPM Console Error when viewing task forms
                        Tihomir Surdilovic Master

                        This is/was a bug with Guvnor which is used in jBPM 5.2. Should be fixed once we pull the latest version in jBPM 5.3. Make sure you do not have spaces in the TaskName property value, so rename "Performance Evaluation" to "PerformanceEvaluation" in your process, regenerate forms, build your package and try again.

                        • 9. Re: Jboss AS 7 & JBPM 5.2 --> JBPM Console Error when viewing task forms
                          jaidev Newbie

                          Thanks Tihomir. I did the same as per your suggestion, but tasks are still not loading, here is the debug. When I log into the console I get "could not connect to task client" error message but processes load. I am not sure if I missed changing any properties file with the right ip address.
