Description Dusty Little

Build Identifier: 20110916-0149

I'm receiving the "is not a function, it is object" when creating a Joined Data Set with a Scripted Data Source. I know the scripted data source works because the data is fetched in the "preview results" step correctly. The error occurs when I choose OK to save the Data Set. The error and issue seems identical to the one described in this post: http://www.eclipse.org/forums/index.php/t/201442/ ,however the solution that worked there is not working here. I have added my jar to the scriptlib and WEB-INF/lib folders of the report.viewer plugin. I have added my jar to the classpath of both java and report builder as an external jar using the full path. I've event tried adding the jar to the jvm classpath.

Reproducible: Always

Steps to Reproduce:
1. Create a scripted data source
2. Use it in a Joined Data Set

I can't reproduce this issue with latest birt.
If you can still reproduce it,could you provide more detail information about
how to reproduce it or a sample report I can test with.

json.jar

Jar file containing the json dependencies the scripted datasources. The source is probably al little dated and could be updated from the git repository, but the all test cases indicate that the code works for this data set.

I've attached an example report that demonstrates the error along with the json.jar dependency and screenshots that show the behaviour I am experiencing.
