Hi again,

i've stepped through a not obfuscated build and I'm pretty sure the method where the null ref exception happens is "UpdateItemLanes" of MindFusion.Scheduling.WinForms.Cell. When I look at the code

Code (C++)
Select All
public virtual void UpdateItemLanes(DateTime? start, DateTime? end)
{
_firstVisibleDateTemp = GetFirstVisibleDate();
_lastVisibleDateTemp = GetLastVisibleDate();
foreach (ICell cell in Children)
cell.UpdateItemLanes(start, end);
}


I see that it is possible that a cell can be null. You wrote you have build in a null check. Was this the method you did or another?

Best regards
Achim

Hi,

We think we managed to locate the problem. This method is indeed related to it, though, according to our investigation, the exception happens in the child cell's UpdateItemLanes method. Check your personal messages for a link to a new version of the control, which contains the potential fix.

Thank you for your feedback regarding this issue.

Regards,
Meppy

Hi Meppy,

I just wanted to leave my feedback about the new version here. The bug seems to be fixed in the latest release, we had a whole week of testing at the customers site and no exception occurred Smiley

Best regards and thanks for your support
Achim
