When you export data with the exportData method of the FormDataIntegration Service, and then import the data using importData, the PDF file size increases dramatically. This problem does not occur if you use the import and export options in Acrobat, or use LiveCycle ES 8.2.1 SP3.
This is a bug in LiveCycle ES2 SP1. Update to LiveCycle ES2 SP2 or later. You can also contact Enterprise Support if you require a patch for LiveCycle ES2 SP1 22.214.171.124.
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.
The Default Render service does not render XDP forms, only PDFs.
You must change the render properties manually for the xfaForm variable and choose another render service.
