[Anonymous]

Hi, when i run my project, i receive this exception:
Execution failed : Failed to generate code.

can anyone help me? that's mean?
I think that the bug is on tMap_5, because it appear when i create it and i link it with others components.

Hello
Which version of TOS do you use?
We can't see what's wrong only from the message, Can you export your job and send it to me via email?

have you tried good ol 'alt-shift-f3' This should restart the generation engine. this has worked for me with previous versions of talend.

alt-shift-f3 does nothing

Finally my job is working!
I've just deleted a tUnite component, re-created and it works.
Thanks!

SOLUTION
When the exception is not any component, create a new workspace and import your jobs to it. Simply so.
