I have a grouping grid which has a variable number of columns.
If, say, the first time the grid has 2 columns and the next time it has 3 columns, it still shows 2 columns. When I checked the columns in the header context menu, I could see the third column but as hidden.
When I cleared the cookies and tried again, I could see the third column.
I do not have any state maintenance code for this grouping grid. Why is it behaving like this? Has any one faced such a problem?
