Get props in List of List of Object based on Specific Index in Sightly

[Bahar]

Hello All,

I have a list which I call rows here, then inside that I have another list which is list itself, but I want to get specific index of that list based on outer list index.(rowsList.index), after that I will get the objects inside inner list to show props.

But it is not going inside   <sly data-sly-list.singleList="${logic.listOLists[rowsList.index]}">

I have these two list in my service:

public ArrayList<ArrayList<List<MyObject>>> listOfLists = new ArrayList<ArrayList<List<MyObject>>>();
public ArrayList<List<MyObject>> singleList = new ArrayList<List<MyObject>>();

each item of singleList is like this:

public List<MyObject> myObject = new ArrayList<>();

How should I get inside that listOfLists based on index of outter list?

What is exactly method I need to make sure it will get name/label/required from myobject?

I know that service is adding correctly to the "listOfLists" and "singleList".

Here is part of my sightly.

<div data-sly-use.logic="xx.xx.model.searchRows">

<table>

     <sly data-sly-list.rows="${logic.selectedRows}">

          <tr>

               <td>

                    <input type="text" id="name" name="name" value=${rows.name}>

               </td>

               <td>

                     <sly data-sly-list.singleList="${logic.listOfLists[rowsList.index]}">

                            <sly data-sly-list.innerList="${singleList.listChildren}">

                                 <h2>${innerList.name} - ${innerList.label} - ${innerList.href}</h2>

                           </sly>

                    </sly>

             </td>

         </tr>

   </sly>

</table>

</div>

Thanks for your time.

In sightly I have created another template and pass parameter to the next template.

Still no luck to get list of list based on index which is passing correctly!

<sly data-sly-test.listOfLists="${logic.listOfLists}">
  <div data-sly-use.infoTemplate="info.html">
  <sly data-sly-call="${infoTemplate.renderInfo @
                      logic=logic, i=rowsList.index, listOfLists=listOfLists}" />
  </div>
</sly>

==========================

<template data-sly-template.renderInfo="${ @ logic, i, listOfLists}">
  <sly data-sly-test="${listOfLists.size > 0 && i < listOfLists.size}"> ====> It is passing this line
  <sly data-sly-test.singleList="${listOfLists[i]}"> ======> This one doesn't pass!!
  .........
  </sly>
</template>

Any Idea why listOfLists[i] is not returning singleList?!

Are you basing this on a SLING MODEL -where you know your collections are properly set?

[Bahar]

Yes, I know the property has been set correctly. In service I have while loop with these:

singleList.add(this.Info1);
singleList.add(this.Info2);
singleList.add(this.Info3);
singleList.add(this.Info4);
listOfLists.add(singleList);

And they have set values which I can see in the logs/debugger & size of each list are same as my db correctly.

My only problem is why I can't get listofLists[i] here!

I have done some changes in my model and add id manually, and I guess I am close to get my result. At least I could get the list based on index. thank you.
