Bruno Dumon commented on COCOON-1777:
-------------------------------------

Hi,

Thanks for your patch.

If I understand it correctly, the following will cause auto-submit to be enabled if there are value change listeners:

      <script type="text/javascript"><xsl:value-of select="$browser-variable"/> = forms_createOptionTransfer('<xsl:value-of select="@id"/>', <xsl:value-of select="@listening = 'true'"/>);</script>

which makes it impossible to disable value change listeners, so a better test would be:

      <script type="text/javascript"><xsl:value-of select="$browser-variable"/> = forms_createOptionTransfer('<xsl:value-of select="@id"/>', <xsl:value-of select="@listening = 'true'  and not(fi:styling/@submit-on-change = 'false')"/>);</script>

Correct?

> Element fd:on-value-changed seems to not work with fd:multivaluefield. I have tried it using Cocoon samples, more specifically I changed fd:multivaluefield[@id='drinks'] to:
>     <fd:multivaluefield id="drinks">
>       <fd:label>Indicate which 2 of the following drinks you'd like to receive:</fd:label>
>       <fd:datatype base="string"/>
>       <fd:validation>
>         <fd:value-count exact="2"/>
>       </fd:validation>
>       <fd:selection-list>
>         <fd:item value="Maes"/>
>         <fd:item value="Jupiler"/>
>         <fd:item value="Leffe"/>
>         <fd:item value="Hoegaarden"/>
>         <fd:item value="Coca Cola"/>
>       </fd:selection-list>
>       <fd:on-value-changed>
>         <javascript>
>           java.lang.System.err.println("Drinks value changed: " + event.newValue);                        
>         </javascript>
>       </fd:on-value-changed>
>     </fd:multivaluefield> 
> So I just added fd:on-value-changed but nothing happend when I was trying to change values of this field. I have no problem with normal field widgets, events work perfectly. I am also sure that it's not client/styling issue because I found that in form instance xml normal field widget have @listening attribute but multivalue field have not.
> I don not know how to debug Cocoon so I am not able to continue investigation.
