Error when open a file

[Anonymous]

I have an error when I open my job: 

An error has occurred. See error log for more details.
java.lang.NullPointerException

Somebody knows how to resolve it?

Thanks!

Hello,

Is there any more error message in log? Are you using talend open studio? On which build version you got this issue?

More information will be helpful for us to address your issue.
