Question: Is there an issue working with node objects in FTL? I am using Alfresco Community 2.1.

My scenario is as follows:

Step 1:
In the JS file of the Web Script I do a lucene search to return a list of nodes.
var nodes = search.luceneSearch(searchstring);

Step 2:
I set a property in model called docnodes with the nodes
model.docnodes = nodes;

Step 3:
In the ftl file i try and access the docnodes object and it throws an error (see below for error details)

<html>
${docnodes.length}
</html>

I know that nodes is not null. I even set the number of nodes directly
model.no_nodes = nodes.length;
and was able to retrieve in the ftl file. in the JS file I am able to loop through the node using a 'for each' and see the node name, id etc etc. so I know that I have valid nodes.

Any help appreciated,

Thanks

Freemarker syntax is different to that of Javascript. Please see the Freemarker documentation for details.

In your case, using

${docnodes?size}‍

should achieve the desired result.

Thanks,
