Apologies for not replying earlier. I missed your initial message.
There was a change in JHS event handler behavior some time ago and I think
that is what is causing your current problems.
Previously events without a handler just took the default action. This was
problematic for a number of reasons. The change was that an event without a
handler gives the alert message you report.
The fix for your problem is to define javascript handlers for those events.
For example,
function ev_radioa_click()
{
// call avascript code as required
// call j code handler with jdoajax(...) as required
return true; // event has been handled
}
I think our app should behave properly if you add appropriate handlers. As
you point out, you do not want to mess with jevedo,
