Any idea?

Are you using an Enterprise Edition version of Talend? It looks like this is to do with the JobScript tab (bottom left corner of the workspace). This is a script representation of the job. You can actually use it to make quick and easy copies of jobs and use it to make changes (but only if you know what you are doing). I am guessing that this could be an as yet undiscovered bug as it appears to suggest that this script is null. 
I'd try and Talend restart and then raise this with Talend if it continues.

I am using the Data Integration version
Talend Open Studio
Version: 6.0.0.20150702_1326

This looks like a potential bug with Talend V6. I intend to download v6 DI tonight. I will see if I get the same issue

Hi dihonore,
Would you mind giving some additional details like: java version, OS, 64-bit/32-bit.
Was your Job working fine in a previous version of TOS? If so, how did you import it? What were you trying to do ?
Cheers
Elisa

Hi dihonore,
Did you point it to the JDK folder instead of JRE folder under Talend Window -> Preferences - > Java -> Installed JREs ->?
Please take a look at KB article about:TalendHelpCenter:Requiring a JDK installation to build jobs starting from version 6.0

Best regards
Sabrina

I tried the 2 paths : "C:\Program Files\Java\jdk1.8.0_51" and "C:\Program Files\Java\jre1.8.0_51".

Same problem : impossible to build a standalone job !

java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)

Interesting. I cannot build a standalone job either with V6. I don't get that error message, but nothing is produced. I am using the 1.7 JDK at the moment and not the 1.8 version.

[Anonymous]

@foquintess: could you try to set it "C:\Program Files\Java\jdk1.8.0_51 \jre"
@rhall: can you add \jre at the end of the java path.
It seems that we could reproduce this pb and solved it with that workaround, but I want to make sure this is the same issue.
Cheers
