I am using Aspose.Cells for Java. Our released product is using 220.127.116.11 and I just tried it with 18.104.22.168.
Our application, in a workbook, creates a data sheet and a separate chart sheet which references the data sheet.
The sheet name is derived by what the user defines for his report name, which can contain punctuation including commas (i.e. they used the comma for a Europian decimal seperator) An example is: "PTMS01 - 2,000mps (Single)"
To set the data range for a series in the chart I create a data range using the following code:
/* Build string of the data range */
dataString = new StringBuilder("'");
dataString.append(dataSheetName + "'!" + cellName + ":" + lastCellName);
Then to add the series I do the following:
int iSeriesIndex = nSeries.add(dataString.toString(), false);
This results in a nullpointer exception.
If the dataSheetName does not include a comma then this works. I have tried to include the name in single quote and double quotes but nothing seems to allow accepting the comma.
The attachment includes the stackTrace from the top down to the last instruction called in our app. The last instruction before the exception is the nSeries.add above.
