Hi Jon,

Nifty code snippet!  However, it doesn't seem that the check works for most 
data types.  While attempting to load GOES Imagery or model data multiple times 
does not result in the data source appearing multiple times, most others that I 
tried (e.g. level 2 and 3 NEXRAD, METAR point obs) do appear multiple times in 
the list of data sources.  Taking a look at the data source properties reveals 
that they are in fact pointing to the same source for each instance.

You can find the zidv bundle on our department's RAMADDA server ... it is made 
with IDV 5.0 nightly build, however the problem occurs in 4.1 too.

Thanks,

Kevin

Indeed! It's so easy that the IDV already has code written that attempts to do 
exactly that:

http://git.io/3uwF9Q

Okay, okay...apologies for the snark. I was able to verify the duplicate 
checker works by attempting to create two identical data sources via the "Sat & 
Radar>Images" chooser. Without knowing the specifics of your situation, here's 
what immediately comes to mind:

* Are you certain that the data sources are identical? An easy way to check 
would be to right click on the data sources in question and view their 
"Details" tabs--identical data sources should have identical details.

* Could there be any issues with bundles?

If you can replicate the problem please consider saving a bundle...or just use 
both "xidv" and "zidv" bundles to be safe.

Good luck!

Jon
