After you upgrade an LC7 installation to LC ES 8.2.1 SP1 and use the Process Upgrade Tool, you may receive the following error accessing a form:

An error occurred trying to create the form. ALC-WKS-007-040

The main cause for the exception is:

Root cause: com.adobe.idp.taskmanager.dsc.client.task.TaskNotFoundException: 
no task found for task ID=2850

This error can occur in 3 situations:

  1. The lc7form variables were not converted to xfaform variables after upgrading the process.
  2. The User component is the version compatible with LC7 and not compatible with LC ES.
  3. There is a problem with the taskid in the dB.


  1. Convert the lc7form variables to xfaform variables manually using the information in the Workbench Help:
  2. Get the updated User component, which is compatible with LC ES and deploy it under the LC7.x Components view. This component is usually deployed for you during the ES installation process. However, if the installation did not have access to your LC7 installation, then you can do it manually. You can find the updated LC7inES components under LIVECYCLE_HOME/configurationManager/upgrade.
  3. Ensure you are using the latest ServicePack for LiveCycle ES.  The latest service packs contain fixes for DB issues related to this error.
