Passing values from JavaScript to Java

[Rob Bugh <ro...@accuwater.com>]

Pardon me if this has been answered already. I'm not a JavaScript expert 
and am struggling to understand how to call a JavaScript from within a 
component, have it compute a value, and return the value back to the 
component. For example, I would like to call a JavaScript and have it 
return a the navigator.userAgent string.

I've look at the examples in the Tapestry In Action book and at the 
contrib Palette component (which executes a JavaScript and retrieves a 
value) and I see how the <set> and <let> statements are creating new 
symbols in the input Map, but I don't see how to add or modify and entry 
in the Map from within the JavaScript.

Can this be done?

Thanks,
Rob
