WinTree: Object reference not set to an instance of an object
posted

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
