Description ehucka 2007-07-12 07:19:18 UTC 
Each watch has null value in automated tests running with latest build (hudson 1641).
Comment 1 ehucka 2007-07-12 07:38:08 UTC 
It is manualy reproducible. It throws an NPE too:

java.lang.NullPointerException

It seems the NPE is thrown and watch with null in Type column is created only when an Object type watch is created
during debugging. The watch is browsable. After restart of debugging it is repaired.

Comment 4 Martin Entlicher 2007-07-12 08:35:47 UTC 
Reproduced. This seems to be a random issue...
Comment 5 Martin Entlicher 2007-07-12 08:46:50 UTC 
There was still one place where forgot to retrieve the evaluated watch, after the fix of issue #109275.

It's fixed now:
