Nicklas Karlsson commented on JBSEAM-3830:
------------------------------------------

Have a look here:

http://fisheye.jboss.com/changelog/Seam?cs=9753&csize=5

I opened up the WorkSheetItem to reveal the data and exit early from the adding of items if null

Yep, I recognize you name (you did work on headers/footers etc?). Thanks, it's easy to work on top of a good library! ;-)

> If the value of an e:cell is null , an exception is thrown due to a lack of null checks in JXLHelper.createCell(). It would be better if the cell value was empty in the case of nulls, just like JSF's and Facelets' <h:outputText value="#{aNull}"/> outputsan empty string when encountering nulls.
> Workaround described below, but it gets very tedious adding null checks for hundreds of cells across multiple worksheets.
