These Lookup tables are opened in a thread:

Code: Select all

procedure TDataDM.LookupServersAddAllStr(DataSet: TDataSet);
begin
  ProcessHintMsg('Lookup Table ''Servers'' is active..');
  Assert(TCustomUniDataset(DataSet).LocalUpdate, 'With LocalUpdate active, Data Changes are cached locally in memory');
  DataSet.AppendRecord([AllStr, '%']);
  DecrementLookupsCountinAsyncMode();
end;

Reverted to '7.1.4 (29-Sep-2017)' and all is well..

We have already fixed the issue. This fix will be included in the next build of UniDAC.
We can send you a UniDAC night build including the fix. Please provide your license number and IDE version to viktorv*devart*com and we will send you a night build.

Thank you Viktor but I'm going to skip that.

Let me explain why you desperately need to change your patching.

When you send out a release we expect a certain amount of testing has gone into that, although judging from my reports since September that's questionable..
After I spend time updating and installing within a minute a bug appears and is reported. Then our only option is to take an overnight build, essentially untested code that may be in Beta state?

The right thing to do is to generate 7.2.6.1 from the original tested code, so that at the very least only bugs are fixed and no new features are added.

[ViktorV]

Thank you for the interest in our products.
UniDAC build with hot fix is planned for next week.

sigh...I have spent DAYS on this problem after the latest update. Should have looked here first, I guess. And I agree - "wait until next week" is not a good answer. All of my projects are now dead in the water. I cannot send anything to any of our customers until this (and the other problem) is fixed.

I have looked at rolling back, but I do not have a full backup of every version - and I also use IBDac and you have to have matching versions. It is not a simple thing to roll back as I then have to integrate with FastReports, etc.

What a mess....

The new UniDAC 7.2.7 with with hot fix for this issue is already available for download now.
