Jelly Evaluate Tag for Array of Objects

[markkeats]

I have the following code:

<g:evaluate>
   var someData = [
   {"PropA":"Value1", "PropB":"Value2"},
   {"PropA":"Value3", "PropB":"Value4"}
   ];
</g:evaluate>
<j:forEach items="${someData}" var="jvar_data">
   ${jvar_data.PropA} ${jvar_data.PropB}
</j:forEach>

The evaluate actually builds the data from other sources, but the result is the same - an array of objects that I wish to display in the page.

Unfortunately the UI Page renders nothing, and if I look in the logs I see the following:

WARNING *** WARNING *** ScopedRhinoObjectWrapper: not a wrappable type: org.mozilla.javascript.NativeObject

Any ideas what's going wrong here?

Hi Mark,

This is JSON notation.

Try using this below code:

<g:evaluate>

  var someData = [  

  {"PropA":"Value1", "PropB":"Value2"},  

  {"PropA":"Value3", "PropB":"Value4"}  

  ];  

</g:evaluate>  

<j:forEach items="${someData}">  

  ${someData[0].PropA} ${someData[0].PropB}

</j:forEach>

Thanks and let me know if any concerns.

Hit Like/Helpful, feedback is appreciated.

Please try this - have tested in my local and its working (add <br/> for clarity of output)

<?xml version="1.0" encoding="utf-8" ?>

<j:jelly trim="false" xmlns:j="jelly:core" xmlns:g="glide" xmlns:j2="null" xmlns:g2="null">

<g:evaluate var="jvar_json" jelly="true" object="true">

  var someData = [  

  {"PropA":"Value1", "PropB":"Value2"},  

  {"PropA":"Value3", "PropB":"Value4"}  

  ];  

  someData;

</g:evaluate>  

<j:forEach items="${jvar_json}" var="jvar_data">  

      <g:evaluate var="jvar_propA" jelly="true" expression="var propA = jelly.jvar_data.PropA; propA;"/>

      <g:evaluate var="jvar_propB" jelly="true" expression="var propB = jelly.jvar_data.PropB; propB;"/>

      ${jvar_propA} ${jvar_propB}  

  <br/>

</j:forEach>

</j:jelly>

Hopefully it helps

Thanks. That's fixed it. It's the nested evaluate tags that seem to be needed within the forEach tag.

Hi there,

I've tried Srikanth Gunuru's solution and it works fine in a Global application. However when I tried it in a scoped application, it's returning null. Has anyone tried it in a scoped application?

Thanks
