Description Stephen Shaw 2014-09-24 20:57:54 UTC
The first time you enter the SortDescriptorsChanged override in the NSTableViewSource oldDescriptors isn't usable. I get this back:

> oldDescriptors
> oldDescriptors.Count()
Method `Count' not found in type `MonoMac.Foundation.NSSortDescriptor[]'.

After the first time through it seems to be fine, but I get ascending twice and then it alternates correctly:
Sort column ascending
Sort column ascending
Sort column descending
Sort column ascending
Sort column descending
Sort column ascending
Sort column descending
Sort column ascending
Sort column descending

This means that the icon in the table column header is off and out of sync as to whether its ascending or descending.

I have checked this issue but I am unable to reproduce this issue.

Could you please provide sample application or steps to reproduce this issue?  So that we can reproduce this issue at our end.

Since we haven't received a report case in two months and the bug report doesn't have enough information to reproduce I'm going to close this. Please attach an example and reopen if you run into this again.
