Trying to enter a TBufDataset.IndexName and it keeps disappearing.

[RedOctober]

I have nothing in the .IndexFieldName property, it's empty.  I have configured a index called cdsUsrIdxLoginID which has a Fields property of LoginID and is ixPrimary.  When I go to the TBufDataSet and try to set the IndexName property, the name I paste into the property disappears and the phrase   'DEFAULT_ORDER' appears instead.

I am sure the field name I used for the IndexDef is correct.  My MaxIndexes is 2 (the default)

What am I missing?  Thanks in advance for any help you can provide.

I have made a small sample project showing the problem.  Maybe I am missing something.

Hi RedOctober,

Clear  IndexDef, IndexFieldName, IndexName then:

Code: Pascal  [Select][+][-]

1. procedure TForm1.FormCreate(Sender: TObject);
2. begin
3.   BufDataset1.MaxIndexesCount := 2;
4.   BufDataset1.AddIndex('LoginIndex', 'LoginID', [ixPrimary, ixUnique]);
5.   BufDataset1.IndexFieldNames:='LoginID';
6.   BufDataset1.IndexName := 'LoginIndex';
7.   BufDataset1.CreateDataSet;
8. end;

PS: Test project attached.

Thank you GetMem.  After some experimentation, I was able to determine that I can set all the index related properties (including defs) at design time.  The only property that cannot be set (which is a bug in Laz 1.9 or Fbc 3.1.1) is the IndexName.

So, in my project code, I simply set the IndexName in code, BEFORE I do a .CreateDataset;

This was the most important clue you gave me, and it solved my problem.  Thank you.

Example:
.. set all other settings in the Lazarus IDE, then hardcode:

Code: Pascal  [Select][+][-]

1.   BufDataset1.IndexName := 'LoginIndex';
2.   BufDataset1.CreateDataSet;
3.
