Don't confuse the general scripting done by the HTMlActionRender and the 
specific feature of Back button disabling.  It is the latter, which is 
optional, that can be used to do remote scripting to allow for disabling 
the back button.  This is also why I asked you to see if the BConfig 
application worked for you, since it does not use back button disabling, 
but does use BAction generated javascript events.  So, does it work for 
you?  If not, that points to a more serious lack of javascript capability 
on the part of Konquerer.

So, I'm not exactly sure how difficult it would be to implement the JSRS 
select demo in Barracuda.  I'd have to take a closer look at how that demo 
is set up to tell you for sure.  Additionally, Barracuda uses a modified 
jsrsClient.js file called ClientServerHTTPLib.js.  You can find it in the 
org.enhydra.barracuda.core.scripts package.  If you have a nice diff tool, 
just do a comparison of the original file and the modified one.  There is 
much in common, but some real differences.  You'll have to tell me if it 
works out.

Note that there is also an BAction#addScriptFunction(String) method where 
you can add your own javascript validation script to be run before anything 
gets sent to the server.  Here is where you can circumvent Barracuda's 
standard event scripting functionality.  You can do whatever you want and 
then return false to keep Barracuda from performing a post.  I posted a 
description of this here..

It would actually be a good exercise to try to implement the JSRS select 
demo in Barracuda.  Maybe we can have it as one of the examples?
