Event handler selection[VoiceXml2.0]- Clarification needed

Hi,

I want to know whether the following explanation and the original post are
as per the behavior specified in the VoiceXML 2.0 Specification.

 

I think that irrespective of the fact that the current input item is filled
or not, the nomatch handler specified inside the input item must be
selected.

 

As specified in the VoiceXml 2.0 specification..section 5.2

5.2 Event Handling

 

"An element inherits the catch elements ("as if by copy") from each of its
ancestor elements, as needed."

 

Also as specified in the Appendix C FIA of the specification..

" If an event is thrown during the execution of a <filled>,
             event handler selection starts in the scope of the <filled>,
         which could be an input item or the form itself. "

 

Comments awaited.

 

Regards,

Harbhanu

A <field>-level nomatch kicks in if the input to the
field did not match the field's grammar. In your case,
the grammar *did* infact match. 

With your current approach, a <form>-level (or higher)
nomatch handler would get invoked. But, if you want
the field to be revisited, you will need to clear its
guard variable.


Hope this helps.
