    copied!<p>I want to add sorting for column in celltable with help of ListHandler. But it doesn't sort. I don't understand why it doesn't work. My code is based on GWT tutorial. Please suggest me something.</p> <p>Contract.java</p> <pre><code>public class Contract implements Serializable { private int contId; private String contOrgName; //getters and setters... } </code></pre> <p>Main.java</p> <pre><code>TextColumn&lt;Contract&gt; orgNameColumn = new TextColumn&lt;Contract&gt;() { @Override public String getValue(Contract contract) { return contract.getcontOrgName(); }}; orgNameColumn.setSortable(true); CellTable&lt;Contract&gt; tableContract = new CellTable&lt;Contract&gt;(); tableContract.addColumn(orgNameColumn, "OrgName"); ListDataProvider&lt;Contract&gt; contractDataProvider = new ListDataProvider&lt;Contract&gt;(); contractDataProvider.addDataDisplay(tableContract); GetContractsServiceAsync getContractsService = GWT.create(GetContractsService.class); getContractsService.getContracts(new AsyncCallback&lt;List&lt;Contract&gt;&gt;() { public void onFailure(Throwable caught) { // Show the RPC error message to the user } public void onSuccess(List&lt;Contract&gt; result) { contractDataProvider.getList().clear(); contractDataProvider.getList().addAll(result); ListHandler&lt;Contract&gt; columnSortHandler = new ListHandler&lt;Contract&gt;(result); columnSortHandler.setComparator(orgNameColumn, new Comparator&lt;Contract&gt;() { public int compare(Contract o1, Contract o2) { if (o1 == o2) { return 0; } if (o1 != null) { return (o2 != null) ? o1.getcontOrgName().compareTo(o2.getcontOrgName()) : 1; } return -1; } }); tableContract.addColumnSortHandler(columnSortHandler); table.getColumnSortList().push(orgNameColumn); } }); </code></pre>

An individual column

Larger individual text columns get their own page to allow for proper reading.
