LINQ Reporting engine throws java.lang.IllegalStateException

Aspose.Words Product Family

Hello,

When accessing fields of array items in a foreach I get an error when the array is empty, even when I put the whole foreach in a conditional checking whether the array is empty.

I’m using:

  • Aspose.Words for Java, v20.6
  • a Word template
  • the ReportingEngine
  • a JsonDataSource

In attachment the Word template and the Java sources of my test (including the JSON input): 220248 case data.zip (10.7 KB)

The error I’m getting is:
java.lang.IllegalStateException: An error has been encountered at the end of expression ‘i.text]>’. Can not get the value of member ‘text’ on type ‘class com.aspose.words.net.System.Data.DataRow’.

How can I solve this?

We suggest you please use ReportBuildOptions as shown below to avoid this exception. Hope this helps you.

final ReportingEngine engine = new ReportingEngine();
engine.setOptions(ReportBuildOptions.ALLOW_MISSING_MEMBERS);
