We have 2 plugins on a job.
Description setter and Text finder.

For successful builds we have another description then failures (see attachment).
We have a text-finder config which marks the build as failed, in that case the failures description should be set.
But we see that even if there is a failure because of the text finder, the description-setter still reports the successful description.

Console output of the job:
....
Description set: Latest build: 28
Checking console output
/home/hudson/.hudson/jobs/install-crd21/builds/2010-08-12_02-01-32/log:
ERROR: SOAP fault during load. Check log for more details.
Finished: FAILURE

So text finder is executed before description setter
