hello,
I am trying to reproduce the problem and I have reproduced it partially but not on the Unigui example projects. I will try to explain when the error message occurs.
i have a TFDQuery with a query with many field including 2 stringfield and 1 integerfield that i want display in grid.
1- i link the query (via datasource)to the grid and i add a column for one of both string field. test : ok, no error
2-i add a editor unimemo to this column. test : ok, no error
3-i add a second column for second string field with unimemo as editor. test : ok no error
4-i add a third column for the integer field. test KO , grow:true error
i try adding a unispinedit as editor for this third column without effect on the error
in my case this third column is not very important in my app, so i remove it. For me, the problem is no longer blocking but i think there is a bug somewhere in the unigui framework.
