Hello
I have a problem when i try to modify chart's data in a presentation.
I open the presentation, I modify some series values and then I save the presentation. Every time I save I get
'java.lang.NumberFormatException: For input string: "."'
but the presentation is saved anyway. But when I open the presentation, click on the chart and then on modify data i get this error: "The linked file isn't available. This error can occur if the linked file has been moved or hasn't been saved. Embedding the data instead of linking it can help avoid this error, but the data won't be updated automatically if it changes in the source file."
