GDBG Sort Problem

[Christopher Dugdale]

Hi,

I''m using a GDBG and I have hooked into the SortHandler event.

In my custom handler I store the expanded state of each row and then I call sort on the datasource. After the sort, I restore the row expanded state.

However if I click in quick succession on the column header to sort, the following exception is produced.

Any ideas what is the cause and how this can be fixed?
