Infragistics UltraCombo - Display Member not shown with guid as valuemember

[m6s]

If anyone has met the problem:

I have setup a ultracombo with values from sql 2000. Valuemember = guid from the table, and DisplayMember property is the Description from the table.
So it's like that :
DisplayMember = Table.Descripti on
ValueMember = Table.Guid

I have now the issue, that the ultracombo does not really show the values but show guid. And this does not happen always at all the combo boxes. But for some. The collation of the table is some SQL_LATIN1_850_ CI_AI, as all the tables. The guid, is...english... ok, the description is a nvarchar.

Has anyone met this problem ever?

I suppose you have verified that the descriptions for those values are actually not the same as the guids?
Is there anything special about the descriptions not being displayed?

No, nothing special. The only thing it is, is that they are greek.
But then again as values in combo box, exist there.

This happens at times to some of the guids also, in a bunch of..1000? guids in a grid.

98% is ok, 2%? has this erroneous behaviour...
