We no longer provide this functionality as it is now considered bad practice. Jobs should be built to not fail or to fail gracefully if they do fail.

This is a VERY DANGEROUS FUNCTIONALITY and I hope Talend will get rid of it because it also clutters the job code.

The problem is, jumping just to a specific sub job does not take into account there are some expected processing before and all the potentially created variables in the globalMap or context are not filled and empty.

It also makes job testing much much more complex.

Conclusion: FORGET this feature as soon as possible!

The better way is to use more jobs with less functionality and put them into a job chain.

You can also get values from an embed job by the tRunJob output flow (filled inside the embed job with tBufferOutput).
