Thank you for the attached sample project and document. We found that there's an issue with the mail merge when using an SQL database as data source.

We fixed the exception handling in this case and the DOCX file now loads without crashing, but the mail merge still does not work. We will analyze the issue further and try to fix the mail merge in with SQL databases in DOCX documents for the future versions of Nevron Open Vision.

Hello,

Thank you for the detailed description of the issue you have experienced. Unfortunately, we couldn't reproduce it. Can you please send us or attach to a forum post the DOCX file you are getting the error with? Another option is to send us a sample project that demonstrates the issue. We will then be able to analyze and debug your code, find out what's wrong and fix it.

Thank you!
