While running Features Analysis, or Appeon Deployment, an error message box pops up and displays "Error loading command string".
Cause: This error typically occurs when the DataWindow syntax is not in the expected PowerBuilder 9 or later format.
-
The application has not been built or upgraded with PowerBuilder 9 or later.
-
When the application is upgraded with a higher PowerBuilder version, some "old" syntax may still be included. This is because PowerBuilder provides backwards compatibility, but Appeon may not support the "old" syntax.
Solution A: Follow the steps below to fix the problem.
Step 1: Verify that no unsupported identifiers are used in the application.
Step 2: Remove or modify the problematic object(s) that contains "old" syntax from the PowerBuilder application by following the instructions in How to locate problematic objects in an application.
Step 3: Terminate Appeon Developer. Terminate the EonADT62.exe process if they are still running in the Windows Task Manager.
Step 4: Run Feature Analysis/Appeon Deployment again.
Solution B: Try the following steps if the problem is not resolved using Solution A.
Step 1: Delete the application profile in Appeon Developer Configuration.
Step 2: Delete the entire application folder under the Appeon Developer installation directory: \Appeon\Developer2016\Project\ApplicationName (indicating the application profile name).
Step 3: Terminate the EonADT62.exe processes if they are still running in Windows Task Manager.
Step 4: Recreate the application profile in Appeon Developer Configuration.
Step 5: Perform the desired Appeon function (Feature Analysis/Appeon Deployment) on the application profile again.
Solution C: If the problem is not resolved with Solution B, try the following steps.
Step 1: Uninstall Appeon Developer from Windows Control Panel > Add/Remove programs, or run the Uninstall program.
Step 2: Delete the entire Appeon Developer folder where Appeon Developer is installed, for example, C:\Program Files\Appeon\Developer2016.
Step 3: Reinstall Appeon Developer and reconfigure Appeon Developer's settings in Appeon Developer Configuration, such as the application profiles, server profiles and deployment profiles.
Step 4: Set the transaction object mapping to the correct data sources for the application in AEM > Application > Transactions > Transaction Objects.
Step 5: Verify that Appeon Server (EAServer extended with Appeon Server components) is running and accepting connections.
Step 6: Perform the desired Appeon function (Feature Analysis/ Appeon Deployment) on the application profile again.
