Problems parsing json

[ajmillar]

Dear all, I have created a webscript that passes back json, example as follows...

{
    "sitetree" : {
        "node" : {
            "name" : "test.html",
            "nodeRef" : "workspace://SpacesStore/a86f1bad-08cc-426c-a5ea-79d3f2e4ed8e",
            "description" : "Test file",
            "icon" : "/images/filetypes/html.gif" 
        } ,
        "node" : {
            "name" : "website1",
            "nodeRef" : "workspace://SpacesStore/f0e810d1-a405-4e14-a654-d116c25d581e",
            "description" : "",
            "icon" : "/images/icons/space-icon-default-16.gif" ,
            "node" : {
                "name" : "website1.html",
                "nodeRef" : "workspace://SpacesStore/410d7d3b-109f-4dac-9164-df50891f3e9d",
                "description" : "",
                "icon" : "/images/filetypes/html.gif" 
            } 
        } 
    } 
}

I call that from within my springsurf file using the following...

// get a connector to the Alfresco repository endpoint
var connector = remote.connect("alfresco"); 
var result = connector.call("/alfrescocms/getsitetree");
model.sitetree = eval( '(' + result + ')' );

And then try to parse it as follows...

<#macro parseChild objectModel>
	<#list objectModel.node as child>
		<li><img src="${child.node.icon}"><a href="${child.node.nodeRef}">${child.node.name}</a></li>
	</#list>
</#macro>
<h3><a href="#">Site Tree</a></h3>
<div>
	<ul>
		<@parseChild sitetree.sitetree />
	</ul>
</div>

But I keep getting the error

freemarker.template.TemplateException - Expected collection or sequence. objectModel.node evaluated instead to freemarker.template.SimpleHash on line 3, column 16 in webscripts/getsitetree/getsitetree.get.html.ftl.

Can anyone offer any insight into what I'm doing wrong. The JSON that is passed back seems to validate without any problem. Perhaps I'm misunderstanding what is possible with Freemarker?

It should be

<#list objectModel as child>

to list the nodes, as objectModel here is the list with many children.

Have a nice day,
Tanausú.

I am having a similar trouble as the OP. Many thanks for the tip Tanausú. I would give it a try
