NullReferenceException opening OOXML file if shared strings XML part has non-default name. Aspose.Cells 8.4.1

Aspose.Cells Product Family
1

Scenario: Aspose.Cells 8.4.1. I try to open XLSM file (attached).


Issue: NullReferenceException is thrown.

During investigation I found out that bug connected with “\xl\sharedStrings.xml” XML part. In the attached file the name of this XML part is not default: “\xl\sharedStrings2.xml”.

I have not found any limitations on the name of XML part with shared strings in Open XML SDK. Moreover, Excel opens this kind of file without any problems.

Thanks,

Hi,


When will the fix be included into the official release?

My concern is whether 8.4.1.5 passed full regression testing. Or only new code changes (fixes, enhancements) were tested? Please tell me if I can include this new dll into my production version or better to wait until you make official release in a month?

Thanks,

Hi,


Thanks for sharing your concerns.

Well, we do perform regression and QA testing before publishing the fixes in the forums. But, we might not include all the test cases when performing tests with the hot fixes. And, yes, sure, you may use this fixed version for your production usage, the fix contains all the functionality and other enhancements full fledged. However, due to time and other certain restrictions, the fixes posted in the forums do not cover all the test cases as compared to the official releases of the product. By the way, our next official version is scheduled to be released in the next week of this month, the schedule may change depending upon certain feasibility factors though.

Thank you.
