topic Issue with returned JSON object in Alfresco Archive https://connect.hyland.com/t5/alfresco-archive/issue-with-returned-json-object/m-p/247128#M200258 <HTML><HEAD></HEAD><BODY><SPAN>I am trying to write a dashlet to display blog posts with a particular tag. I originally used just a repo-tier webscript to search for and display them (modified from the blog category search example) and a web-view dashlet to show them on dashboards, however this seemed inelegant and sometimes displayed http basic auth requests when it shoudn't have.</SPAN><BR /><SPAN>Obviously the first hurdle I came to was the search API not being root scoped for share dashlets. I realized I couldn't do the whole job with a single webscript, that I would need one on the repo-tier and another to handle the dashlet.</SPAN><BR /><BR /><SPAN>I modified my original web-script to return JSON instead, and it now returns valid (at least according to jsonlint) json. Here's what it returns if I hit the webscript URL -</SPAN><BR /><BR /><PRE class="language-none line-numbers"><CODE>{<BR />&nbsp;&nbsp;&nbsp; "nodes" : {"0":"workspace://SpacesStore/dc9d18c0-9c69-4256-8203-f246a760b6e9","1":"workspace://SpacesStore/d2afcbad-de5a-4eec-b421-b7b223b3fc5a"}<BR />}<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN></CODE></PRE><BR /><SPAN>I followed quite a few tutorials to get to this stage, mostly from Jeff Potts. I especially found the most recent document one helpful, however it was for a single result, I think my issues arise from trying to return an object. Originally I was getting an issue from my dashlet when it got to the obj = eval('(' + json + ')'); step, it gave me an error that I was missing a ']', even though I never even opened any square braces. Other posts on stackoverflow led me to this being an issue with trying to eval() an object, so I tried to access the object as json.data, json.nodes and just plain json instead as well - all show as undefined and give an error on the next step when I attempt to .length the variable.</SPAN><BR /><BR /><SPAN>Here's the section of my dashlet's javascript to deal with the result - </SPAN><BR /><BR /><PRE class="language-none line-numbers"><CODE>&nbsp;&nbsp;&nbsp; var json = remote.call("/someCo/blog/public?maxPosts=" + maxPosts);<BR />&nbsp;&nbsp;&nbsp; if (json.status == 200)<BR />&nbsp;&nbsp;&nbsp; {<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //obj = eval('(' + json + ')'); - issue with missing ']'<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;obj = json.nodes;<BR />&nbsp;&nbsp;&nbsp; }<BR />&nbsp;&nbsp;&nbsp;logger.warn(obj);<BR />&nbsp;&nbsp;&nbsp;nodes=obj;<BR />&nbsp;&nbsp;&nbsp;logger.warn("Obj received of length " + nodes.length);<BR />&nbsp;&nbsp;&nbsp;var results = [], result;<BR />&nbsp;&nbsp; // Turn nodes into result objects<BR />&nbsp;&nbsp; for (var i = 0, j = nodes.length; i &lt; j; i++)<BR />&nbsp;&nbsp; {<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Create core object<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; node = getNodeFromString(nodes[i]);<BR />&nbsp;&nbsp;&nbsp;&nbsp; // Cut the site name out of displaypath<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; blogSite = node.displayPath.slice(20,node.displayPath.lastIndexOf("/"));<BR />&nbsp;&nbsp;&nbsp;&nbsp; // Get the Person node for the blog creator<BR />&nbsp;&nbsp;&nbsp;&nbsp; blogUser = people.getPerson(node.properties["cm:creator"]);<BR />&nbsp;&nbsp;&nbsp;&nbsp; blogContent = node.content.slice(0,350) + "…";<BR />&nbsp;&nbsp;&nbsp;&nbsp; result =<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; {<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;blogContent: blogContent,<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; name: node.name,<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; title: node.properties["cm:title"],<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; createdByUser: blogUser.properties["cm:firstName"] + " " + blogUser.properties["cm:lastName"],<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;createdByUserName: node.properties["cm:creator"],<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;blogSite: blogSite,<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;dateCreated: node.properties["cm:published"]<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; };<BR />&nbsp;&nbsp;&nbsp;if (result.blogContent &amp;&amp; result.name &amp;&amp; result.title &amp;&amp; result.createdByUser &amp;&amp; result.createdByUserName &amp;&amp; result.blogSite &amp;&amp; result.dateCreated)<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if (node.qnamePath.indexOf("cm:post") != -1 )<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;results.push(result);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;else<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;logger.warn("Public Blog Post Dashlet - An item, nodeRef:" + node.nodeRef + ", has been assigned the public tag but is not a blog post (lacks cm:post in qnamePath).
