Hello.

I am using version 1.8.0 (from 19.sep.2002).
for some reason I can't use any higher versions, or even run your src code.
So I am hoping that you are familiar with this error, and be kind enough to 
help me.

I have a code that runs in a nested loop and creates cells in the current row.
cell = row.createCell((short)i);
after that i add data to the cell (string data that might contain numbers\date 
or even an empty value but the format is string).

In most of the time I get a ClassCastException for FormatRecord at 
Workbook.java line 560.
For the command row.createCell(). Each time in a different cell and for variant 
datas.
I couldn't find any consistency that indicates which cell will cause the error.
(Not a null String\Date\number\etc... On the cell before. Or any other thing I 
could think of)
(This happens usualy when i am building larger tables.) 

Thanks for your time,
Barak.
