Hi,

Today I installed Talend BD Studio 8 at my laptop and imported the project I currently created in Talend 7.3.1 Studio.

IN standard folder, ther is no error to open and run the job but when I copied same job into Big Data Batch folder and opened the job, I got the error like below

"java.lang.NullPointerException error"

--- From errror log

Problems occurred when invoking code from plug-in: "org.eclipse.jface".

Move the same job from standard job node to Big Data Batch node? there are different job type, for example, some components do not exist in Big data batch job. Why you do it? Maybe I misunderstand it?

I want to move/convert the existing standard job to big data batch job so that and run the job. My question is why I can't open the job once I moved the job from standard to big data batch folder?
