During evaluation of your GridWeb product (for .NET) we found another critical bug for us.
We need to load Excel file (exported form .NET GridWeb control) using Apache POI library (http://poi.apache.org/index.html)
In case of version 3.2 of POI, we get the following exception:
java.io.IOException: Cannot remove block[ -1 ]; out of range[ 0 - 10 ]
In case of version 3.7 of POI, we get the following warning:
Warning, header block comes after data blocks in POIFS block listing
Probably there is something wrong with excel file generated by your GridWeb control
Please look at line 195 in this file http://www.docjar.com/html/api/org/apache/poi/poifs/storage/BlockAllocationTableReader.java.html. In this situation excel file probably won’t be read to the end.
Unfortunately, we have to use POI in version 3.2 (another 3rd party application uses it), so we hope that you fix this bug.
It seems that version 126.96.36.1990 of GridWeb was the last good one. Problem described by me occurs from version 188.8.131.52
