Ouch. Thanks for the report. I am sure the Freemed team would like to know 

Digging a bit deeper it seems one of the milestones for the current prerelease 
has been to seperate user interface and backend. That said they are waiting 
for the UI team to complete the work so I guess the vaccination stuff is there 
in the backend.


The webinterface they had was close to unusable for todays standards. They 
redid it by using GWT (google web toolkit) but since GWT is JAVA based they 
must have used a translating layer like JSON-RPC (I can be wrong)

Any way you put it modern browsers only understand Javascript. So while GWT is 
JAVA based it compiles JAVA code into Javascript.

They currently use php on their backend I believe so they need the bridge from 
php to javascript via GWT ( I can be wrong). I read in their roadmap that they 
plan on replacing the php stuff (I guess) by a Java backend.

When they do this they can use GWT natively I guess.

For now freemed public demo seems to be a bit on the slow side (lacks 
snappiness) but that is mostl likely due to devel code, preview status and 
maybe server location. GNUmed's public database is often much slower for 
people. I looked like some of their widgets could use some sort of caching.
Anyway I hope they succeed in what they are doing. 

There are various other effort like pyjamas which tries to compile python into 
javascript. In the end there is a huge variety of toolkits and frameworks

There seems to be no straighforward way to have a python application use GWT 
or extJS or any Javascript toolkits.

Feel free to correct me as the above statements are made knowing little and 
reading a lot lately about web developement.

I guess the biggest problem with webinterfaces it that developers often mimic 
desktop applications. However on the desktop there is no back button. User 
like me put a lot of effort into breakin any webapp by creative use of the 
back button.
