    <p>I would like to implement something similar to the Cell Validation showcase example, which can be found here </p> <p><a href="http://gwt.googleusercontent.com/samples/Showcase/Showcase.html#!CwCellValidation" rel="nofollow">http://gwt.googleusercontent.com/samples/Showcase/Showcase.html#!CwCellValidation</a></p> <p>After looking through the code and trying to implement it, there seems to be a class/variable deffinition missing for template. which shows up in the code in 2 places</p> <pre><code>public ValidatableInputCell(String errorMessage) { super("change"); if (template == null) { template = GWT.create(Template.class); } this.errorMessage = SimpleHtmlSanitizer.sanitizeHtml(errorMessage); } SafeStyles safeColor = SafeStylesUtils.fromTrustedString("color: " + color + ";"); sb.append(template.input(pendingValue != null ? pendingValue : value, safeColor)); if (invalid) { sb.appendHtmlConstant(" &lt;span style='color:red;'&gt;"); sb.append(errorMessage); sb.appendHtmlConstant("&lt;/span&gt;"); } </code></pre> <p>After searching the web i found a few examples of what the template variable definition should be and came up with</p> <pre><code>interface Template extends SafeHtmlTemplates { @Template("&lt;input type=\"text\" value=\"{0}\" tabindex=\"-1\" size=\"{1}\"&gt;&lt;/input&gt;") SafeHtml input(String value, SafeHtml safeStyles); } private Template template; </code></pre> <p>with the above code added in there are no compiler warning howver when the code is executed i get this error</p> <blockquote> <p>SafeStyles used in a non-CSS attribute context. Did you mean to use java.lang.String or SafeHtml instead?</p> </blockquote> <p>Any ideas of how to fix this problem?</p>

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.

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