Hello,
On my winForms App I have a UltraComboEditor and a WinTree. According to ultracomboeditor value selected, the WinTree refresh it's values.
The problem begins when I scroll the ultracomboeditor values with my mouse quickly. It appears an error: "Object reference not set to an instance of an object". On my stacktrace it appears that the erros occurs on this method: at Infragistics.Win.UltraWinTree.UltraTreeNode.ResolveExpansionIndicatorAppearance(AppearanceData& appData, AppearancePropFlags& requestedProps, Boolean isMouseOver).
Can you help me out?
Thank you,
Maria
