Exception thrown: Cell shading sprm is too long

I am dynamically building a Word document using the DocumentBuilder based on content from our CMS. This tool has been running well for many months now, but today I’m getting the following exception when I go to save the document. Can you shed any light on what this error means so that I can analyze our content to find what’s different about this particular piece of content that would cause it to crash?

Exception:

Cell shading sprm is too long. For free technical support, please post this error and the file in the Aspose.Words Forums <https://forum.aspose.com/c/words/8>.

Can you please attach the template document and a code snippet so that we could reproduce the error.

No, I cannot. The content is extremely large and pulled from so many areas. I don’t have time to try to isolate which particular area is causing the save to not work. Can you describe some scenarios where this exception is generated? It might give me insight as to something in our content that could cause it, since that exception message doesn’t give me any clue as to what went wrong.

The explanation might be a bit technical.
Microsoft Word binary document format originated long time ago and has a lot of qirks. In this particular case all formatting attributes of cells in a row are written into a data structure that has limited length (220 bytes if I’m correct) and that’s limitation of the DOC format.
Your table probably has quite a lot of cells, so many that it does not fit into this length and we have a check in our code to detect this situation and report it.
In general, it is possible for us to provide a resolution for this case because of the extensions that were added to the DOC format in never Microsoft Word versions. We did not support this until today because it must take quite a lot of cells and a lot of formatting specified for them to trigger this condition and we considered such documents unlikely.

I have logged this problem to our defect base as issue #1260. We will try to fix it in one of our next releases.
Best regards,

Hi Team,

Is this issue fixed. I’ve hit the same issue using AsposeWordsForJava 13.5. I feel, it’s still the same with the latest version.

Thanks,
Kumar
