InfoPath Dev

Hi Everyone,

This is my first post and I am new in infopath development. I don't like to ask a question immediately when I joint but I am really hopeless

Anyway, I have a problem about code in published form. Code below working properly on the designer at local machine;

test.SetValue("Test")

But, after published form when I try to run it "Object reference not set to an instance of an object" error has occured.

I read to many post and article but I couldn't find the reason of this error.

Thanks in advance.

I realized that, this problem occured on the filled forms, but new forms has no problem. I hope it's helped....

 Thanks.

I think I figurout what is going on...

I added some fields and try to update it with the code but old form's xml doesn't contain this fields, so when I try to setVaule infopath generate error.

 Now I have to find out how can I add these fields to old forms....

InfoPath has a built-in feature to upgrade previous versions of forms and add missing fields when the form is opened (on the Versioning tab of Form Options).  Have you tried that?

Hi Jimmy,

 Thanks for reply, and yes I solve my problem with the Versioning tab of Form Option.

 Thanks again.
