Aspose Crash during Mail Merge

I have just built a little bit of test code to try and run a mail merge on an example document that has been provided to me by my customer and am getting an exception thrown in the Aspose library (“Object reference not set to an instance of an object”, stack trace below). When I ran this test before having a license it “worked” in that it didn’t throw any exception, but after adding these lines:





License l = new License();

l.SetLicense(“c:\Aspose.Words.lic”);





it now has a problem. I suspect why it worked without specifying the license before-hand was because it was only processing the first page and didn’t get as far as whatever the bug is that causes the problem.



The merge I’m attempting is fairly complex - the word document has quite a few rules and uses IF, SET, COMPARE etc. Just to be thorough I tested the license with a simple merge document I created in Word and it worked perfectly, so it must be that the Aspose library is crashing during the merge due to the complexity.



Can you please let me know if there is anything I can do to work around the problem below. I really like the look of your product and would be disappointed if it can’t handle the documents we need for this project.



Here is the Stack Trace:

The code I’m using is:





License l = new License();

l.SetLicense(“c:\Aspose.Words.lic”);



Document doc = new Document(“c:\Merge.docx”);



String[] names = null;

String[] vals = null;



using (Microsoft.VisualBasic.FileIO.TextFieldParser p = new Microsoft.VisualBasic.FileIO.TextFieldParser(“c:\Data.csv”))

{

p.TextFieldType = Microsoft.VisualBasic.FileIO.FieldType.Delimited;

p.SetDelimiters(",");

p.HasFieldsEnclosedInQuotes = true;



names = p.ReadFields();

vals = p.ReadFields();

}



doc.MailMerge.Execute(names, vals);



doc.Save(“c:\Result.pdf”);





The input Data.csv file contains 309 name/values for this particular file but for other documents could contain up to about 500.

Hi

Thanks for your request. Could you please attach your template and data source here for testing? We will check the issue and provide you more information.

Best regards,

Unfortunately I cannot as the resulting document and input data is confidential and I will not be able to get authorisation to distribute it. Is there any other way you can investigate this problem?

Hi

Thanks for your request. Actually we do not need your output document and real data. We need only your template and sample data that will allow us to reproduce the problem.

Best regards,

Hi, I have cut away at the document until I’ve got down to a few bits of text left that are causing the problem. It didn’t matter what I had for the csv data either, so I’ve included just a single field csv file here. What I need to understand is firstly if you are going to fix the problem, and if so how soon could that be done? I need to submit my proposal tomorrow and want to have some confidence that your product will actually work for the intended purposes. Please see attachment.

Hi

Thank you for additional information. I managed to reproduce the problem on my side. Your request has been linked to the appropriate issue. You will be notified as soon as it is resolved.

Unfortunately, currently I cannot provide a reliable estimate. The responsible developer will analyze the issue and then we will provide you more information.

Best regards,

The issues you have found earlier (filed as WORDSNET-5359) have been fixed in this .NET update and this Java update.
