Page definition is not found while running JSR286 portlet in WebCenter app

Question

Hi All,
I have ADF application which has 3 different task flows 1. my service 2. my car 3. my bike.
which I have placed into a single bounded task flow called repairTaskflow.
I have created a JSR286 portlet out of a repairTaskflow. I am trying to consume it in an Webcenter application. When I place the portlet on to the page in Web center application
and run the page. I see the following error in the console.
oracle.jbo.NoDefException: JBO-25002: Definition ***.xxxx.view.pageDefs.applications_task_flow_applications_task_flow_CreateEmptyApplicationPageDef of type Form Binding Definition is not found.

</portlet-app> In all the 3 task flow there is at least one method activity placed either as the default activity or part of activities.
In service page taskflow the default activity is a method activity. If I convert the service-task-flow alone as a portlet, it failed. showing the similar error : pagedef not found.
Then I created the portlet out of car task-flow whose default activity is a page. This time I can view the portlet, the car list page. Once I click create button on that page which again goes through a method activity, then it failed showing the error mentioned above
It seems where ever there are method activities on the taskflow, the portlet cannot find the pagedef and its throwing error . I have cross checked the deployed war file and all the pagedef's are bundled into it.
Any suggestions are much appreciated.
Thanks,
Morgan.

Answer 1

Hi All,
I solved this issue. The path of pagedef files was not recognized when I publish the taskflows as portlets. Though it runs when I place it as a region on jspx file.
The folder structure where I placed pagedefs earlier was some thing like this in ViewController -> Application Resources
com.mycomp.view.pagedefs
When I wanted to consume the portlet in the portal application, all the pagedefs under this path were not visible to the portlet.
Once I change the pagedef folder to the immediate folder after the Application Resources, it found all the pagedefs
Now my folder structure in ViewController -> Application Resources
view.pagedefs
Is this a bug? or Am I missing some thing.
Thanks,
Morgan.
