Passing Javascript array to Java Use API

[B_Stockwell]

Following up on this discussion: http://help-forums.adobe.com/content/adobeforums/en/experience-manager-forum/adobe-experience-manage...

Now that I have an array of different parameters, I'd like to pass them to a Java file where im implementing the Use-API. I've dont some digging and have found that when I try to pass the object returned by my JS file, that is read as a io.sightly.js.rhino.HybridObject.

I can find no documentation for this type aside from SVN commits (which actually refer to org.apache.sling.scripting.sightly.js.rhino) to the sling project over the last 6 months or so, nor can I figure out how to include this in my Maven configuration.

Is there a way to implement something like this now, or do i need to wait for HybridObject to be accepted in the sling project?

Are you able to share a basic code sample what you are trying to do?

Perhaps I can help you.

Sure

...(edited from my original post to be slightly more clear)

Sightly HTML

<div data-sly-use.newsList="newsList.js">         ${newsList.test}         <div data-sly-use.test="${'com.uc.news.UseTest' @ params = newsList}">             test output: ${test.p}         </div> </div>

newsList.js:

"use strict"; use( function () { var params = {}; params.limit = 0; params.page = 0; params.term = ""; params.articles = ""; params.articlesExclude = ""; params.alsoQuery = "false"; params.author = ""; params.authorsExclude = ""; params.contacts = ""; params.dateRange = "unlimited"; params.startDate = "0"; params.endDate = "TODAY"; params.hasVideo = false; params.tags = []; params.anyall = "any";         params.test = "success"; return params; });

UseTest.java

package com.uc.news; import com.adobe.cq.sightly.WCMUse; public class UseTest extends WCMUse { String p = ""; @Override public void activate() throws Exception { String p = (String) get("params", String.class); //Throws Error: } }

HTML ouput:

<div> success <div> test output: </div> </div>

I got this working with the following code..., have a look if this is also ok for you:

JAVA: import io.sightly.java.api.Record; import com.adobe.cq.sightly.WCMUse; public class UseTest extends WCMUse { public Record params=null; public String p; @Override public void activate() throws Exception { params = get("params", Record.class); p = (String) params.get("dateRange"); } }

Sightly:

<div data-sly-use.newsList="newsList.js">
${newsList.dateRange}
        <div data-sly-use.articles="${'yourpackage.UseTest' @ params=newsList}">
            ${articles.p}
        </div>
</div>

Thanks! That works.
