    <p>In my app, I have Photos that have associated comments. When I retrieve the target list of photos I save the high / low keys of the Photos to contain the list of comments I query for. </p> <p>The problem I am having is that the Query will not return the comments for the last photo. </p> <p>It's almost as if the GREATER_THAN_OR_EQUAL is operating as GREATER_THAN. </p> <p>I can get the query to work by deconstructing the high key and adding 1 to its id.</p> <p>Is this a bug or am I expecting the wrong thing ?</p> <p>SDK Release 1.6.1 SDK Timestamp: Mon Dec 12 14:53:13 PST 2011 API versions: [1.0]</p> <p>Here is my code, below that is the work around code.</p> <pre><code>Query q = new Query (EntityNames.EventPhotoComment.name()); q.addFilter( Entity.KEY_RESERVED_PROPERTY, Query.FilterOperator.LESS_THAN_OR_EQUAL, highPhotoKey); q.addFilter( Entity.KEY_RESERVED_PROPERTY, Query.FilterOperator.GREATER_THAN_OR_EQUAL, lowPhotoKey); q.addSort(Entity.KEY_RESERVED_PROPERTY, Query.SortDirection.ASCENDING); PreparedQuery pq = ds.prepare(q); Iterator&lt;Entity&gt; dbDataIterator = pq.asIterator(); </code></pre> <p>Work around code.</p> <pre><code> long id = highPhotoKey.getId(); Key parent = highPhotoKey.getParent(); highPhotoKey = KeyFactory.createKey(parent,EntityNames.EventPhoto.name(), id+1); </code></pre>

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.
