Error retrieving field value from bean

[gbaldeck]

 Hi, I have a report that is getting an error when run. It is saying that in one of my datasources there is a field that it can't get. However I've looked in all my jrxml files and this field doesn't exist anywhere. Also, the datasources I'm using dont have this property defined anywhere either. It is non-existant in all my java files and jrxml files but I'm still getting the error. What could be causing this?

 

Here's the stack trace:

 I fixed it. It was a problem with one of my datasources. I was passing null as the datasource when the list was empty when I should have just been passing an empty list.
