tprejob and joblets

Anonymous — Sat, 16 Nov 2024 13:22:45 GMT

Hi,
I have two questions regarding the use of tprejob and joblets. I can't seem to find any relevant documentation for either of them.
1. If a job has a prejob and includes a joblet that has a prejob, how is the prejob execution order defined? For example job A has a prejob that requires context parameters loaded via jobLet B's prejob. How can I ensure that job A's prejob fires *after* joblet B's prejob?
2. I can't create a "component OK" trigger from a tprejob to a joblet, even if the joblet has a "trigger input" defined. Can somebody please explain to me why?
thanks.
TIS 3.2.2 Build id: r33000-20091120-1230
addendum:
I've found a solution to point 2 - the joblet needs to be set as "startable" (Joblet tab->extra->startable). I'd missed this in the docs and found a reference to it at issue 11446

Using a tRunJob to call jobA. for example,
father job:
jobletB

oncomponentok

tRunJob_1(call JobA)
