Hi everyone!
I am copying cells (value and cellstyle) from one workbook to another,
using the code below.
Now i have two xlsx files, where src.xlsx is the source - where the values are copied from - and the
second one is dst.xlsx.
The dst.xlsx has conditional formatting, e.g. the cells of the first column are "green" if the value is "1" (numeric).
The problem is, the copied cells are not formatted automatically anymore.
That means, the copied cell in column one has the value "1" but is not green (at least not in excel, in libreoffice it is).
It's easy to fix it by hand: Simply select the cell, right click, select filling options and click on the already selected "automatic" or "none".
Afterwards, the cell is correctly displayed in green.
The reason for this behaviour seems to be the following:
POI creates a new FillStyle:
even if a cell is set to NONE by:
The correct (or at least "working") solution would be to set the cell to the predefined (fillId=0):
Excel seems to apply conditional formatting only to two sorts of cells:
1) Those who have the "default" fillstyle - that means fillId=0
2) Those, who have set the fillstyle to: patternType="solid">
Looks like a bug in POI, or at least in Excel... right?
Any suggestions for a workaround? What I need is a way to set the FillStyle (only) to the default one (fillId=0)
Greetings, Flo
