Subject eval.xml
Date Thu, 20 Oct 2005 19:55:07 GMT
Hi

I've followed the example given in
http://jakarta.apache.org/poi/hssf/eval.html to use
HSSFFormulaEvaluator.evaluate but a NullPointerException is thrown.
The same problem is described in
http://article.gmane.org/gmane.comp.jakarta.poi.devel/9767/.
Using the solution Amol gives in that message everything works fine.

Here is a diff to the docs to add the missing line:
