WebApp change filtering var & Station from AND --> OR (needed for Grouping issue #77)
We further discussed internally with and we recommend to change the way variable and stations are filtered.
- We think the "OR" logic is more suitable for our needs.
- Moreover is required since we want to group the variables. We might consider to downloaded and extra file a sort of *.log file simply with the list of the stations and respective variable downloaded. Users can easily see if something is missing...or we could even write it this *.log file which variable on which stations are not available.
- We might consider adding a pop-up info when the user attempts to download a particular selection, something like "please be aware that some of the variables downloaded are not available for all the stations, please read the log file for more details".
In this way we help the users, we can group the variables and we avoid confusion. @alessandro.zandonai please check if I missed something.
