    <p>I'm using a CellTable to display entities' information stored in the Datastore. Data type of the parameters are String and int. </p> <p>I decided to use SelectionCell to show the value of every parameter. This works perfectly when it comes to String data type, but it fails with int data type. </p> <p>For instance, I have a parameter called:</p> <pre><code>String name; </code></pre> <p>Possible values for this parameter are: "Name1", "Name2" or "Name3". I have these values in the SelectionCell, so if an entity has a parameter name = "Name2", SelectionCell displays "Name2"</p> <pre><code>List&lt;String&gt; names= new ArrayList&lt;String&gt;(); names.add("Name1"); names.add("Name2"); names.add("Name3"); SelectionCell nameCell = new SelectionCell(names); Column&lt;Entity, String&gt; nameColumn = new Column&lt;Entity, String&gt;(nameCell){ @Override public String getValue(Entity object){ return object.getName(); } }; cellTable.addColumn(nameColumn, "Name"); </code></pre> <p>Now, I have a parameter called:</p> <pre><code>int age; </code></pre> <p>Possible values for this parameter are: 18, 19, 20,... ,65. I have these values in the SelectionCell, but if an entity has a parameter age = 25, SelectionCell doesn't display that value, it displays 18.</p> <pre><code>List&lt;String&gt; ages= new ArrayList&lt;String&gt;(); for(int i = 18; i &lt;= 65; i++){ ages.add("" + i); } SelectionCell ageCell = new SelectionCell(ages); Column&lt;Entity, String&gt; ageColumn = new Column&lt;Entity, String&gt;(ageCell){ @Override public String getValue(Entity object){ return "" + object.getAge(); } }; cellTable.addColumn(ageColumn, "Age"); </code></pre> <p>How can I solve that?</p> <p>Cheers.</p>

    1. COHave you tried converting the int to a string before rendering it? Select boxes prefer to have string values.

    2. COYes, I'm converting to String since SelectionCell only accepts List<String> values. I added the 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.
