If I have TableNode with several rows, some of them spanned into singleline row and expanded, CurrentScrollRow is higher than 0. Then calling this causes exception:

node.Rows.Clear();
int row = node.AddRow();
node[0, row].ColumnSpan = 2;
node[0, row].Text = "something"; // here 

the Rows.Clear() call doesn't reset the CurrentScrollRow counter and then, when drawing into TableNode cell some internal checks for row and col count throws an exception, that row number must be non-negative and lower than total row count, but that's true.
My solution is set CurrentScrollRow to 0 before this code block.
Expected behavior: CurrentScrollRow should be set to 0 when Rows.Clear() is called.

Using node.RedimTable(0, 0); instead of node.Rows.Clear(); resulted in the same exception - CurrentScrollRow has the previous value and caused exception when painting. I guess the problem is not in setting node/row count, but in resetting it.
The question is, how to redraw TableNode, if underlying object has changed - Added/Removed items, etc.?
