[las_users] las V7beta with V6UI

[bcheng@xxxxxxxxxxxx]

Hello all. We just upgraded to LAS V7beta with the V6 UI installed and  
Ferret 6.1 (V7 UI seems to be full of problems). While checking to  
make sure all the capabilities work, we found a problem with the  
difference plot for the compare two dataset option.
This was traced to the ferret jnl file (in  
tomcat/webapps/las/WEB-INF/classes/resources/ferret/temp) having the  
wrong data_0_url argument ,
i.e. , it was setting data_0_url = $data_0_dataset_url, when it's supposed
to read the value inside the jnl file indicated by $data_0_dataset_url  
(the actual location of the data).

Is there a fix for this ?

Thanks for any tips...
