Freemarker Template Issue For Select Tag When Multiple is True
Please see: https://issues.apache.org/jira/browse/WW-4153 which I'm working
on.
I thought about modifying template/simple/select.ftl to:
<#assign i = 1 >
<#if parameters.multiple?default(false)>
<#if (parameters.id?? && parameters.name??)>
<input type="hidden" id="__multiselect_${parameters.id?html}"
name="__multiselect_${parameters.name?html}" value=""<#rt/>
</#if>
<#if (parameters.id?? && !parameters.name??)>
<input type="hidden" id="__multiselect_${parameters.id?html}"
name="__multiselect_${parameters.id?html}" value=""<#rt/>
</#if>
<#if ( !parameters.id?? && parameters.name??)>
<input type="hidden" id="__multiselect_${parameters.id?html}"
name="__multiselect_${parameters.id?html}" value=""<#rt/>
</#if>
<#if ( !parameters.id?? && !parameters.name??)>
<input type="hidden" id="__multiselect_${i}" name="__multiselect_${i}"
value=""<#rt/>
<#assign i = i + 1>
</#if>
<#if parameters.disabled?default(false)>
disabled="disabled"<#rt/>
</#if>
/>
</#if>
But I think my solution will not work if the user has 2 or more select
inputs with multiple="true" and no name and no id attribute specified. I
think both would get a name value of __multiselect_1
Any suggestions would be appreciated for how to create a unique id and name
value for the hidden input type when the user uses a select input type with
multiple="true" and no name and no id attribute is specified.

Maybe do it simple - if there is neither "id" nor "name" just use
default("") as it doesn't make sense to generate hidden fields for
tags that wont be send back to server. Or even add global <#if> to
remove the whole section.
