> The multi value field with fi:styling list-type="double-listbox" relies on forms_onsubmitHandlers to select all items in the right selection list before submitting. In an ajax form, it seems like forms_onsubmit is not installed on the form, so handlers are not called; in forms-field-styling.xsl this is clearly stated :
>       <xsl:choose>
>         <xsl:when test="@ajax = 'true'">
>           <xsl:attribute name="dojoType">CFormsForm</xsl:attribute>
>           <xsl:if test="@ajax = 'true'">
>             <script type="text/javascript">cocoon.forms.ajax = true;</script>
>           </xsl:if>
>         </xsl:when>
>         <xsl:otherwise>
>           <xsl:attribute name="onsubmit">forms_onsubmit(); <xsl:value-of select="@onsubmit"/></xsl:attribute>
>         </xsl:otherwise>
>       </xsl:choose>
> I don't think installing forms_onsubmit() also on ajax forma is a wise solution, but maybe we should call it from inside the ajax code, or at least check and execute onsubmit_handlers. If not, also the free-form multivalue field editor will not work correctly.
> What's the best way to fix this issue?
