CSPro Users Forum

Hi,
We have a CAPI application developed in CSPro 8.0 that is launched through a MENU program. The application was working perfectly in version 8.0. After upgrading to CSPro 8.1, we started experiencing issues. The problem occurs when a new case entry is made. Upon completion, the following errors appear:
1) "There was an error writing to the data source: The case could not be found."
2) There was an error saving the case.
3) An error message showing the data file/path.
4) "Fatal error in entry engine. Aborting the entry operation."

After these messages, the application closes automatically(on both Android and Windows).
We have verified the application paths, data source settings, and related configurations. Since the application worked correctly in CSPro 8.0 and the issue only started after upgrading to 8.1, we suspect there may be a version-specific issue or a change in behavior related to partial saves.

One additional observation is that, when i tried to do the entry with same id part again, the case save saved successfully without any error. Later i tired the new entry with new ID , same issue persist. Has anyone experienced a similar issue in CSPro 8.1 with case handling and partial save causing error?
Any guidance would be greatly appreciated. Thanks in Advance.
I am attaching screenshots of the error messages for reference.

Regards,
Vipul

Thanks Vipul. This happened with me. Every thing was working fine, as soon as I migrated to new version 8.1, this issue popped up

We're having the same problem, currently with version 8.1 updated in June 2026. When registering cases and attempting partial recording, an error message appears and the application closes, resulting in data loss.
Is there a fix for this problem?

We are experiencing exactly the same issue after upgrading to CSPro 8.1, on both Android and Windows.
The real problem:

When launching an entry application via PFF with a new case ID, in CSPro 8.0 the entry engine automatically created the case in the data file. In CSPro 8.1 this behavior changed — the engine searches for the case and if it does not exist throws a fatal error.
Error sequence:

"There was an error writing to the data source: The case could not be found."
"There was an error saving the case."
Error message showing the data file path
"Fatal error in entry engine. Aborting the entry operation."

Key observations:

Occurs on both Android and Windows
The exact same code worked perfectly in CSPro 8.0
Retrying with the same case ID sometimes succeeds
Not reproducible on demand — intermittent failure

Temporary workaround:

We pre-create the case from the menu application before launching the PFF. This stabilizes the flow but is not a real fix.
Question: Is this an intentional behavior change in 8.1 or a regression? Is there a PFF parameter or setting to restore the automatic case creation behavior as in 8.0?
Thank you.

@juan_barreto we are investigating this issue. Are you able to send us a test app to cspro@lists.census.gov ?

Thanks to Shafique, we were able to reproduce the issue. Will publish a fix ASAP. In the interim, if a new case has been partially saved once, exit the app and launch the app again to modify the partially saved case (as Juan said, make sure the case "exists") This is not the intended behavior. Sorry for the inconvenience.

A fix for this issue is available now in the latest app published on Google Play. The Desktop fix will be available later next week. Please let us know if this fix resolved your issues. Thanks.

Thanks a lot SAVY for your continous efforts to resolve this issue. I ran all my applications on my phone and no issue dectetced/faced. I confirm that this is working fine with me atleast. Thank you soooooo much.

We have sent you an email with a series of issues we detected related to file creation.
