macro errors

Hi,
I am getting various macro errors:

<#macro sentiment scmr model><#if scmr??>
  <#assign senti = "${scmr.results[model]}">
    <#if senti??>
      <td>${senti} ---- ${senti.sentimentType}</td>
      <td>${senti.score?html}</td>
    <#else><td align="center" colspan="2">none</td>
    </#if>
</#if></#macro>

first error:

POSITIVE(1.0/1) ---- Expected hash. senti evaluated instead to freemarker.template.SimpleScalar 

this is coming from "${senti} ---- ${senti.sentimentType}"
apparently, "senti" is the string representation of the object,
not the object itself.
how do I fix that?

second error:

Error executing macro: sentiment required parameter: scmr is not specified.

this is coming from this invocation:

 <@sentiment model=model scmr=result.title/>

here `result' is non-null, but result.title is null.
I do check for that in the macro, but, apparently, it has to be done
outside.  Why?

Thanks!
