[IDV #LOC-679604]: Moving the subset area in a data source fails - sometimes

> Hi Yuan.
> Your bundle works for me.
> I added more displays, moved the subset region several times, and changed the 
> subset times. It worked almost perfectly.
> 
> Somehow, a couple of the displays got offset by 1 time level in all this

It sounds like a bug.

I have spent some effects researching your bundle, but not sure why the data 
change listener get lost after loading the bundle. If you can manage to 
reproduce this error, document the detail information and this may help me to 
find out the bug.
