I have forced Cava to include SpredSheet::WriteExcel and I guess that will do it?

UPDATE: Some more details. What seems to be the problem is when I'm adding a chart in a separate worksheet. I have several other charts that I'm using in a worksheet also containing some other data and that works fine. The difference is that to add these charts the command embed_chart is used while to add the chart in the separate worksheet (which is not working) the command add_chart_ext is used.

To generate the bin-files used by these functions, the chartex function is being used and all seems to work well during that process.

I guess the thing that is the most puzzling is that it all works in an unpacked version but when packaged by Cava, everything works but the add_chart_ext command which produces an error.

Any ides around how to make this work are highly appreciated!
