    <p>I have form with dateTimeField, and ListView. ListView looks like that:</p> <pre><code>final ListView&lt;String&gt; countryView = new ListView&lt;String&gt;("country", model.&lt;List&lt;String&gt;&gt;bind("country")) { @Override protected void populateItem(final ListItem&lt;String&gt; item) { final String country = item.getModelObject(); item.add(new ValidationDisplayableLabel("country", country, new String[] { modelPath })); item.add(new AjaxLink("deleteLink") { @Override public void onClick(AjaxRequestTarget target) { model.getObject().getCountry().remove(country); if (issPeriod) { addButton.setVisible(true); countryTextField.setVisible(true); findButton.setVisible(true); } if (target != null) target.addComponent(rowPanel); } }); } }; countryTextField = new ValidationDisplayableTextField("countryCodeInput", model.bind("oneCountry"), "job.country.value"); **countryView.setReuseItems(true);** rowPanel.add(countryView); rowPanel.add(countryTextField); addButton.setOutputMarkupPlaceholderTag(true); rowPanel.add(addButton); </code></pre> <p>And the addButton looks like that:</p> <pre><code>AjaxSubmitLink addButton = new AjaxSubmitLink(LinkNames.addCountry.toString()) { @Override public void onSubmit(AjaxRequestTarget target, Form form) { if (model.getObject().getOneCountry() != null) addCountry(); if (target != null) target.addComponent(rowPanel); target.addComponent(form.getPage().get("feedbackPanel")); } @Override protected void onError(AjaxRequestTarget target, Form&lt;?&gt; form) { onSubmit(target, form); } }; </code></pre> <p>The thing is, that when I fail my dateTimeField (e.g. set hours to 100), enter country code in countryTextField, and press on addButton, it displays validation message in feedback panel, that hour range is incorrect, but don't add the country. This is because my model isn't updated. Maybe there is a way to update it manually? So validation message will be displayed, but the country listView still could be updated? </p> <p>Submit of the whole form is on other button, so logically it is normal to add a country even if there is a validation error in dateTimeField. </p> <p>Thanks!</p> <p>P.S. i've read a lot of posts about similar problem, but most of them were solved with .setReuseItems(true), but it doesn't work in my case. </p> <p>P.P.S Apache wicket 1.4.17</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.
