Job conductor fails when trying to generate a Job, with the following error in the Client Log:
Error: 'Generate' can't be done: In the execution task "XXX", the context "Default" does not exist for the specified job or is not set, check it!
Stop your TAC.
Empty the folders TalendInstall\tac\apache-tomcat\temp and TalendInstall\tac\apache-tomcat\work.
This actually forces an new check out of the whole project in the TAC. This is a time consuming task.
It looks like the TAC has a problem with huge projects. One solution is to reduce the projects size by splitting the project.
I had a project with about 70 jobs - no problem at all and a project with 800 jobs - always a problem. We have split to project into 3 different projects and now the TAC works more reliable (more - not 100%!) but the situation is much better than before.
