How can I loop through json in the gsp each tag?

Question

I have the following code:

<g:each var="question" in="${confHolder.config.faq}">
  <h1>${question.question}</h1>
  <h1>${question.answer}</h1>
</g:each>

In my conf file I have the following json:

faq = [{"question":"What is this", "answer":"This thing"}, {"question":"What is this", "answer":"This thing"}];

I know that I'm reading in the file correctly because I can do:

<script type="text/javascript">
  var faq = ${confHolder.config.faq} 
  for(var ii=0; ii<faq.length; ii++)
    alert(faq[0].question);
</script>

And it will alert out my question.

How can I loop through my json in the each tag and print out the questions and answers in the <h1></h1> tag?

You need to parse the json into a list of maps:

This should work for grails 1.3.7

<g:each var="question" in="${grails.converters.JSON.parse( confHolder.config.faq )}">
