Question

Hello,

I face a problem with SpreadsheetView. I need to update the rows of the spreadsheet, so as indicated in other post I change the Grid after calculating it. My table contains cells with checkboxes. The problem appear when I scroll horizontally after changing the Grid. A NullPointerException is raised :

#!java

I really need to do this. Is there a fix or do you plan to fix it ?
