BuildReport throws NullPointerException with Option REMOVE_EMPTY_PARAGRAPHS using Java

Aspose.Words Product Family

Hi, i’m using Aspose Words JAVA since 10 year now.
I tried to migrate from version 20.8 to 21.3 and all the reports which were generated with linq report engine with previous version don’t work anymore with new one.

I tried to investigate and found that using option REMOVE_EMPTY_PARAGRAPHS in conjunction with “foreach” in the template on a property of the main object causes this runtime error:
Exception in thread “main” java.lang.NullPointerException
at com.aspose.words.zzYV9.zzX(Unknown Source)
at com.aspose.words.internal.zzA7.zzZ(Unknown Source)

If i don’t add the option REMOVE_EMPTY_PARAGRAPHS everything works ok.
Same problem happens with vesion 20.11 and higher too…

Please provide a correction as soon as possible !!
thanks

Thank u very much for the quick answer.

It’s not the first time that errors like this appear in new versions of the product.
Maybe you could improve the prepdoduction tests planned for the java versions.

Hi Tahir,

i cannot use this workaround.
If i understood well, you are going to solve this issue in a new versione, right ?

So i’ll wait the new version whith the correction.
Thanks
