When trying to read in our excel we got this warnings : [WARNING] Unknown Ptg 14 (20) at cell (2,85) When trying to figure out what was going wrong, we found in our excel file at that cell the following formula : =IF(CG3>=CF3,100%,0%) If we remove the % signs in the formula and run again, the warnings are gone. However the result is as expected, the value with % signs.
14 is, as you can probably guess, ptgPercent. Its currently not implemented. I'll get to it, but you should probably be OK with a workaround. The appearance of a '%' sign in the result cell would have nothing to do with the return value of the function, but would depend on the formatting of the cell.
My bad. I didn't see this bug when I created my own one later on. About to close this one as a duplicate: http://issues.apache.org/bugzilla/show_bug.cgi?id=39136
*** Bug 39136 has been marked as a duplicate of this bug. ***
Incidentally, the patch is available in bug 39136, I thought it would be messy to upload the same file twice.
40024 fixed.
