> template/simple/doubleselect.ftl contains the following snippet to preselect the subselection:
>         for (i = 0; i < ${parameters.id}Group[x].length; i++) {
>             ${parameters.id}Temp.options[i] = new Option(${parameters.id}Group[x][i].text, ${parameters.id}Group[x][i].value);
>             <#if parameters.doubleNameValue?exists>
>             	if (${parameters.id}Temp.options[i].value == '${parameters.doubleNameValue}') {
>             		${parameters.id}Temp.options[i].selected = true;
>             		selected = true;
>             	}
>             </#if>
>         }
> In the case of a multiple subselect the doubleNameValue is a collection of ids. In this case the single ...Temp.options[i].value is compared to a collection object which fails for all items.
> I´d suggest a patch like:
>         for (i = 0; i < ${parameters.id}Group[x].length; i++) {
>             ${parameters.id}Temp.options[i] = new Option(${parameters.id}Group[x][i].text, ${parameters.id}Group[x][i].value);
>             <#if parameters.doubleNameValue?exists>
>                    <#if parameters.doubleMultiple?exists>
>                          for (j = 0; j < ${parameters.doubleNameValue}.length; j++) {
>                              if (${parameters.id}Temp.options[i].value == ${parameters.doubleNameValue}[j]) {
>                                ${parameters.id}Temp.options[i].selected = true;
> 	     selected = true;
> 	   }
> 	}
>                       <#else>
> 	 if (${parameters.id}Temp.options[i].value == '${parameters.doubleNameValue}') {
> 	   ${parameters.id}Temp.options[i].selected = true;
> 	   selected = true;
> 	 }
>                       </#if>
>                  </#if>
>             }
