New Unidac 4.1.4 has serious bugs in table commit

[pimentel_flores]

Hi Unidac Team,

I just downloaded and installed the new 4.1.4 version of the unidac
and now my project is showing this kind of errors

Access violation at address 0062BAAB in module 'Project.exe'. Read of address 00000016

and

AddRefStr failed
(D:\Projects\Delphi\Dac\Common\Source\MemData.pas, line 7952)

and also this piece of code is not working anymore, it throws erros and cannot save information to my tables

Code: Select all

 
               uniquery.ApplyUpdates;
               uniquery.CommitUpdates;
               uniquery.RefreshRecord;

im using delphi 2007, unidac 4.1.4 with connection to mysql 5.1

Hello,

We already fixed the problem with Access Violation on ApplyUpdates. Please describe the situation (the code) when the "AddRefStr failed" assertion failure occurs in more details. Also, please note that you don't need to call ApplyUpdates before CommitUpdates. If there are pending updates in a dataset, the CommitUpdates method calls ApplyUpdates.

Sorry for being late on replying,
I was assigned to other project but now will get back on this issue.

so far i think the issue is the refreshrecord call, i think this cannot be called after the commit.

will try removing this and will let you know

Code: Select all

               
uniquery.ApplyUpdates; 
uniquery.CommitUpdates; 
[b]uniquery.RefreshRecord;[/b]

I cannot reproduce the problem with the "AddRefStr failed" assertion failure in the way you pointed out above. Please try creating a small sample to demonstrate the problem and send it to andreyz*devart*com .
