Devart Forums

Hi UniDAC team,

On the 26th of december 2019 i've registered an blocking issue using the support form on your website, and recieved an email confirming that my request was recieved.

In my request i've send you a test project that explains and demonstrates the problem (see attached file):
The UniQuery object uses the wrong column-reference in the params when generating the "UPDATE" statement. This results in data-loss because the data in the main-object (FROM part of the query) gets overwritten by the data of one the joined tables.

On the 21th of Januari I still haven't heard from you, so i've send you an email (see mail thread), and got a disappointing response. As of today the still hasn't been any communication about this issue. I don't know:
- If it's being worked on.
- If it will be resolved.
- When the fix will be released.

As i've explained in my mail earlier, this issue is blocking and results in data-loss. Because I'm certain it doesn't only effect me I'm posting this on the forum to inform all UniDac users about this. Hoping you're going to fix this issue shortly.

Hi Maxim,

As of the 26th of December there has been no communication concerning the request we've send you.
Furthermore I have to say that I'm very disappointed in the way the request is handled:
1. The only response I've received from your end is that you're investigating the issue.
2. Lack of an interface for managing the request (unprofessional)
2.1 It’s not possible to monitor the status of the request.
2.2 It's not possible to add additional information.
2.3 Keeping a log/chat of communication for both parties.

Due to this described issue we're unable to release new versions of our software. We're also unable to implement a work-around, or quick-fix, solving the problem in our software because this has a huge impact in the architecture of our applications. So we're forced to wait for a solution in the UniDAC package.

Hope to hear from you soon.

PS: for more information about the issue or questions relating the request you can also contact me using the provided information below.

Hello,

We continue to investigate the issue, hopefully, we'll get the result soon. We'll update on the progress in the nearest future.

Best regards,
Maxim

We've reproduced the issue and fixed it. The fix will be included in the next build of our product. As a workaround, we can send you a night UniDAC build including the required changes. For this provide us with your license number and IDE version you are interested in For your convenience, please use the e-support form https://www.devart.com/company/contactform.html

Thanks for you're response.

I'm very disappointed in the way the request has been handled. It's very sad that I had to submit a form post to get some reaction about the status of this ticket. Furthermore I still don't have a clear answer on the question when the issue will be fixed. When is this build and release of UniDAC scheduled so i can integrate this in our release roadmap?

Hi Maxim,

Could you please answer my question?
When is the release, in which the bug is resolved, sheduled?

Greets,
Roy

We're planning to release a new build of UniDAC at the beginning of Match.

Hi Roylieben

just for your information. I have just downloaded and tested your example project.

On my site I cannot reproduce the issue you described.

I am using PostgreSQL 12.2 on Linux, Delphi 10.2.3 Tokyo and UniDac 8.0.1.

So it seems that the issue must have been introduced with UniDac 8.1.2.

Hi James,

Thanks for testing and providing me with the additional info that the problem is not present in version 8.0.1.
As of today Devart has release a new version of the UniDAC components (8.1.3). Let's hope the problem is fixed.

If not we can always fallback to version 8.0.1. Thnx!

Greets,
Roy

Please clarify whether that issue occurs in the latest version 8.1.3 of UniDAC.

Due to the outbreak of the corona virus we're unable to test and verify the bugfix on short term.
Therefore I want to suggest to close this ticket for now. When we run into the same issue again, or verify that the bug is nog fixed we will open this ticket again, or register a new one.

We will be waiting for news from you and we will support you if there are any issues concerning our product work

Hi Maxim,

We have tested extensively, and have not ran into this issue. So i think it's safe to say the problem has been solved.

Best regards,
Roy

We are glad to see the problem resolved. Please don't hesitate to contact us with questions concerning our product usage.
