    <p>You are not accounting for null geo types which will cause an exception on the original code. Use <code>peek()</code> to check for null. I've modified the code to handle this and it prints both objects.</p> <pre><code>class MyReader { public void readBegin(JsonReader reader) { try { reader.beginObject(); while (reader.hasNext()) { String name = reader.nextName(); if (name.equals("results")) { reader.beginArray(); while (reader.hasNext()) { read(reader); } reader.endArray(); } else { reader.skipValue(); } } reader.endObject(); } catch (Exception e) { e.printStackTrace(); } } public void read(JsonReader reader) throws Exception { String from_user = null, from_user_id_str = null, from_user_name = null, text = null; URL profile_image_url = null; reader.beginObject(); while (reader.hasNext()) { String name = reader.nextName(); if (name.equals("from_user")) { from_user = reader.nextString(); System.out.println(from_user); } else if (name.equals("from_user_id_str")) { from_user_id_str = reader.nextString(); } else if (name.equals("from_user_name")) { from_user_name = reader.nextString(); } else if (name.equals("geo")) { if (reader.hasNext()) { JsonToken peek = reader.peek(); if (peek == JsonToken.NULL) { reader.skipValue(); } else { reader.beginObject(); while (reader.hasNext()) { // String s = reader.nextName(); if (name.equals("coordinates")) { reader.beginArray(); double latitude = 0; double longitude = 0; while (reader.hasNext()) { latitude = reader.nextDouble(); longitude = reader.nextDouble(); } reader.endArray(); } else { reader.skipValue(); } } reader.endObject(); } } } else if (name.equals("profile_image_url")) { profile_image_url = new URL(reader.nextString()); } else if (name.equals("text")) { text = reader.nextString(); } else { reader.skipValue(); } } reader.endObject(); } </code></pre>

    1. COthx mate, so the problem is caused by the "null" object that I didn't handle?

    2. COYep. You can handle that with `reader.peek();`

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
