I have a tree grid that crashes each time A node is going to be displayed.
I see that in CExtTreeGridDataProvider::_Tree_MapRowToCache, this line:
CExtTreeGridCellNode * pNode = m_arrGridVis.GetAt( nRowNo );
returns NULL, even though the row line is valid. The entry is within the array, because the array size is bigger then the nRowNo, so, for some reason the array contains NULL entries - how can this be?
Please note that the same think does not happen in 2.82.
Please fix.
Thanks,
Ron.
