Subject [jira] [Updated] (FREEMARKER-70) Loop Variables Not Resolving when used as marco arguments
Date Fri, 11 Aug 2017 14:39:00 GMT

     [ https://issues.apache.org/jira/browse/FREEMARKER-70?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Bill Parkinson updated FREEMARKER-70:
-------------------------------------
    Description: 
When invoking a macro inside of a #list  the loop variable is not in scope to be used resolving
the argument values to the macro call.

Example
{{

<#macro button caption>
content irrelevant.
</#macro>


<#list ["a","b","c"]>
<#items as loopvar>
${loopvar?counter} -- works
${loopvar?index} -- works
<p class="${loopvar?index}"> -- works
<@button caption="${loopvar?index}" /> -- FAILS
</#items>
</#list>

}}

The @button macro call fails with the message:
The left hand operand of ?index must be a loop variable, but there's no loop variable in scope
with this name: loopvar

Shouldn't loopvar be in scope for evaluating those macro argument values?
