Description Josh Micich 2008-08-27 20:04:53 UTC
Follow-on from bug 45698.
After fixing that bug, POI can read+write back the same sample file (attachment (id=22488)) without throwing an exception, but some data is lost.  The output file is less than 1.4Mb but probably should be more than 4Mb.  Excel opens the output file without reporting an error.  However, all but a few rows of content is lost from most sheets.  Sheets without merged cells seem unaffected.

The problem seems to stem from the presence of MERGEDCELLS records between the row/cell records.  The OOO documentation suggests that MERGEDCELLS should be written after the 'Sheet View Settings Block' which is well after the Row Blocks.  Excel(2007) seems to follow this standard.

This example file was probably created by some other application besides Excel.

Paul, do you know which application produced the file in question?
