----------------------------------------
Thanks Daniel,
Indeed this fixes a NPE which is throwed else.
Now I wanted to see if there are no regressions. And I used
https://localhost:8443/workeffort/control/ChildWorkEfforts?workEffortId=9002&workEffortId={9002%2C+9002}&trail=9002|9003|9005
Unfortunately this fails when you click on the root node. It's *not related to
this patch* since it can be reproduced at
https://demo-trunk.ofbiz.apache.org/workeffort/control/ChildWorkEfforts?workEffortId=9002&workEffortId={9002%2C+{9002%2C+9002}}&trail=
My time is over this morning, I will get to it later when I will get a chance.
Of course no needs to say that any help is appreciated.
