Error filtering dataset

[d.bernaert]

Hi,

One of my customers sometimes receives an error message when filtering a dataset.

There is a shortcut on the screen to filter the dataset by a certain criteria and now and then he receives the following error message and everything hangs.

It seems to happen when DataSet returns a RecordCount = -1.

It should not happen normally. Workaround is to ignore this and return an empty grid.

Workaround:

        if rCount < 0 then
          raise Exception.Create('Dataset returned invalid "RecordCount": ' + IntToStr(rCount));

 

You can replace above line  with:

if rCount < 0 then rCount := 0;
