This must be an oversight on our part. Custom appointments seem not to be completely consistent with recurrence in the current version of Planner.

I extended the Item interface to provide better recurrence support for custom items. You can download the preliminary build from here: https://mindfusion.org/_temp/_trial_Planner.NET.zip.

You should add a new override in your derived class as follows:

protected override void CopyOccurrence(Item master)
{
  _contactRow = master.ContactRow;

  base.CopyOccurrence(master);
} 

Furthermore, you could add the following code in the setter of the ContactRow property.

if (Recurrence != null)
  Recurrence.MarkException(this, false); 

This is to ensure that an item will be marked as exception when its ContactRow has changed.

I believe this would help.

Ok - ive managed to suss out why i was getting the errors.

The manifest error was because of old entries in the license file licenses.licx - removed them and i was working again.

The properties missing from the item was because i was not checking the recurrence state and was trying to set it to e.item every time.  This is ok for normal items but for a recurrence i had to use the i.item.recurrence.master!

Its rather complicated how it all gangs together around recurrence and exceptions.  Im also storing the data in an SQL database so making sure i set everything ok is tricky.

Some better samples with recurrence would be nice rather than the ones to set multiple items in the tree.

Oh - also - the items in the zip attached create a bug in the control when if you click onto an appointment then click off it a white text box appears in the cell.  Didnt do this in the last version from what i remember.

I will be posting a complete example showing how to use recurring custom items without losing custom property values in the next few days. Check back soon and thanks for your patience.
