Issue
If you are trying to render a form in Workspace, you may encounter the following exception in the server log:
2007-08-28 16:39:16,604 INFO [com.adobe.livecycle.formdataintegration.server.FormData]
ALC-FDI-001-307: Processing importData operation on source document 182270.
2007-08-28 16:39:16,963 ERROR [com.adobe.livecycle.formdataintegration.client.ImportFormDataException]
ALC-FDI-001-305: Operation aborted: malformed PDF or data.
…
exception: flex.messaging.MessageException: ALC-WKS-005-028: A problem occurred in the Render Service.
Please review the render orchestration for this process.
This exception can occur especially when you have created a process, dragged an XDP form from the repository in Workbench to the variables view to create a variable. It will automatically create an xfaForm type variable, and use the Default Render service.
Reason
The Default Render service does not render XDP forms, only PDFs.
Solution
You must change the render properties manually for the xfaForm variable and choose another render service.
