    <p>I am trying to stringify a typical Java object using the <a href="http://www.json.org/javadoc/org/json/JSONObject.html#toString%28%29" rel="nofollow">toString()</a> method from org.json. However, Collections or Array type members in my beans are stringified in the form of byte arrays. I have set out a sample code to illustrate the problem.</p> <p>Here is what I do expect:</p> <pre><code>{ "nonWorkingDays":[ "Saturday", "Sunday" ], "workingDays":[ "Monday", "Tuesday", "Wednesday", "Thursday", "Friday" ], "days":[ 1, 2, 3, 4, 5, 6, 7 ] } </code></pre> <p>And here is what I am getting instead:</p> <pre><code>{ "nonWorkingDays": [ { "bytes": [ {}, {}, ... ], "empty": false }, { "bytes": [ {}, {}, ... ], "empty": false } ], "workingDays": [ { "bytes": [ {}, {}, ... ], "empty": false }, { "bytes": [ {}, {}, ... ], "empty": false }, ... ], "days": [ {}, {}, ... ] } </code></pre> <p>Finally, here is my code:</p> <pre><code>/* Week.java */ import java.util.ArrayList; import java.util.Arrays; import java.util.List; public class Week { private List&lt;String&gt; workingDays = new ArrayList&lt;String&gt;(); private String[] nonWorkingDays; int days[]; public Week() { String[] workingDaysArray = new String[] { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday" }; workingDays.addAll(Arrays.asList(workingDaysArray)); nonWorkingDays = new String[] { "Saturday", "Sunday" }; days = new int[] { 1, 2, 3, 4, 5, 6, 7 }; } public List&lt;String&gt; getWorkingDays() { return workingDays; } public String[] getNonWorkingDays() { return nonWorkingDays; } public int[] getDays() { return days; } @Override public String toString() { return "Week [workingDays=" + workingDays + ", nonWorkingDays=" + Arrays.toString(nonWorkingDays) + ", days=" + Arrays.toString(days) + "]"; } } /* WeekTest.java */ import org.json.JSONException; import org.json.JSONObject; public class WeekTest { public static void main(String[] args) throws JSONException { Week myWeek = new Week(); JSONObject myWeekJSON = new JSONObject(myWeek); String myWeekJSONString = myWeekJSON.toString(2); System.out.println(myWeekJSONString); // Formatted JSON string System.out.println(myWeek); // Output from Week's toString() } } </code></pre> <p>Btw, the Week's toString() method output's the following:</p> <pre><code>Week [workingDays=[Monday, Tuesday, Wednesday, Thursday, Friday], nonWorkingDays=[Saturday, Sunday], days=[1, 2, 3, 4, 5, 6, 7]] </code></pre> <p>Edit:</p> <p>The problem seems to be with <a href="http://mvnrepository.com/artifact/org.json/json/20090211" rel="nofollow">this maven artifact</a>. After updating to the source from <a href="https://github.com/douglascrockford/JSON-java" rel="nofollow">this github repo</a> I got everything fixed. Please see comment below.</p>

    1. COTested your code, worked for me - I have the correct display. Maybe there is a bug in your `org.json` library ?

    2. COThanks Chafouin. Your guess is correct. I have been using [this maven artifact](http://mvnrepository.com/artifact/org.json/json/20090211) which is the latest on maven repository as of yet. But that release is probably outdated. After using the source from [this github repo](https://github.com/douglascrockford/JSON-java) my program started to work as expected. I found the link to this repo from json.org website. However, no maven artifact seems to be available for this latest source code.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
