Hi Alexander,
If I understand you correctly, I have a solution that could work.
When viewed as an item (by iteself), the URL is just a plain string that
can be edited.
When viewed in a collection, the URLs are rendered as links (but for some
reason my Firefox does not actually respond when I click on the URL, but
all the mark-up seems OK).
See bottom for the Factory, which must be added to
META-INF/services/org.apache.isis.viewer.wicket.ui.ComponentFactory
e.g. mine is:
isis.example.UrlPanelFactory
Hi Martin,
With the following Java:
/**
* Panel for rendering strings as links.
*/
public class UrlPanel extends ScalarPanelTextFieldParseableAbstract {
private static final long serialVersionUID = 1L;
private static final String ID_LINK = "externalSite";
public UrlPanel(final String id, final ScalarModel scalarModel) {
super(id, ID_SCALAR_VALUE, scalarModel);
}
@Override
protected IModel<String> getScalarPanelType() {
return Model.of("stringPanel");
}
@Override
protected Component addComponentForCompact() {
System.out.println("addComponentForCompact()");
Fragment compactFragment = getCompactFragment(CompactType.SPAN);
final String objectAsString = getModel().getObjectAsString();
final ExternalLink link = new ExternalLink(ID_LINK,
objectAsString, objectAsString);
compactFragment.add(link);
scalarTypeContainer.addOrReplace(compactFragment);
return link;
}
}
I found that I had to overload most of the ScalarPanelAbstract.html and
the ScalarPanelTextFieldAbstract.html to create:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";
xmlns:wicket="http://wicket.apache.org";
xml:lang="en"
lang="en">
<body>
<wicket:panel>
<div class="scalarNameAndValueComponentType"
wicket:id="scalarTypeContainer">
<div class="form-group" wicket:id="scalarIfRegular">
<label wicket:id="scalarName" class="scalarName
control-label">[Label text]</label>
<span class="scalarValueWrapper">
<div class="scalarPlaceholder">
<span class="scalarValueInput">
<span class="editing">
<wicket:child/>
<wicket:container wicket:id="scalarValueContainer"/>
<a wicket:id="editProperty" href="#"
class="edit fa fa-pencil-square-o"/>
</span>
</span>
<span wicket:id="associatedActionLinksRight"
class="associatedActionLinksRight">[drop
down]</span>
</div>
<span wicket:id="feedback" class="help-block"></span>
<span wicket:id="associatedActionLinksBelow"></span>
</span>
<div class="clearfix"/>
</div>
<wicket:container wicket:id="scalarIfCompact">
</wicket:container>
</div>
<wicket:fragment wicket:id="text">
<input type="text" name="scalarValue" class="form-control
input-sm scalarValue" wicket:id="scalarValue" />
</wicket:fragment>
<wicket:fragment wicket:id="compactAsSpan">
<a wicket:id="externalSite"></a>
</wicket:fragment>
</wicket:panel>
</body>
</html>
Finally, the factory. This is a horrible hack.
Basically, I check for any string property that starts with "url".
Ideally this should be an annotation or something, but I could not figure
out how to pick up annotations from the property in the "aapliesTo" method
of the factory:
public class UrlPanelFactory extends ComponentFactoryScalarAbstract {
private static final long serialVersionUID = 1L;
public UrlPanelFactory() {
super(String.class);
}
@Override
public ApplicationAdvice appliesTo(IModel<?> model) {
if (!(model instanceof ScalarModel)) {
return ApplicationAdvice.DOES_NOT_APPLY;
}
ScalarModel scalarModel = (ScalarModel) model;
PropertyMemento memento = scalarModel.getPropertyMemento();
if (memento != null){
String identifier = memento.getIdentifier();
final ApplicationAdvice appliesIf =
appliesIf(identifier.startsWith("url"));
return appliesIf;
}
return ApplicationAdvice.DOES_NOT_APPLY;
}
@Override
public Component createComponent(final String id, final ScalarModel
scalarModel) {
return new UrlPanel(id, scalarModel);
}
protected SpecificationLoader getSpecificationLoader() {
return IsisContext.getSessionFactory().getSpecificationLoader();
}
}
