Re: java.util.Properties as Form Model
This indeed solves the trick. I'm not sure this is a bug, since the
propertyresolver is a general system and Hashtable is just an exception to
normal javabean rules.

java.util.Properties as Form Model
Hey,
I'm trying to create a form with a CompoundPropertyModel to fill a
java.util.Properties object dynamically.
Form form = new Form<>("form", new
CompoundPropertyModel<>(properties));
form.add(new TextField("host"));
form.add(new TextField("port"));
This works correct when I start from an empty java.util.Properties object.
If I have an existing java.util.Properties object (with filled data)
and I remove the value in the html page, I want the key-value pair to be
deleted from the Properties object.
With my current implementation I get a stacktrace (because it tries to
write a null value in the java.util.Properties object)
java.lang.NullPointerException
at java.util.Hashtable.put(Hashtable.java:432)
at
org.apache.wicket.core.util.lang.PropertyResolver$MapGetSet.setValue(PropertyResolver.java:803)
at
org.apache.wicket.core.util.lang.PropertyResolver$ObjectAndGetSetter.setValue(PropertyResolver.java:644)
at
org.apache.wicket.core.util.lang.PropertyResolver.setValue(PropertyResolver.java:144)
Has anybody have an idea how best to create this behaviour?
Thanks in advance for your help!

dynamic form (with list + add/remove)
Hey, I was looking for a good example for creating a dynamic form with a list and add/remove functionality. I looked at the ListView, but this article from Martijn's blog tells to use a RepeatingView http://wicketinaction.com/2008/10/building-a-listeditor-form-component/ this article is from 2008. Is this still the prefered way to do this? Or are there other good examples?
Re: Unknown tag name with Wicket namespace: 'panel'
The html is right next to the javacode. I understand that Link does not
normally have a panel, but i want to have one.
This code is actually copied from wicket-bootstrap.
https://github.com/l0rdn1kk0n/wicket-bootstrap/blob/master/bootstrap-core/src/main/java/de/agilecoders/wicket/core/markup/html/bootstrap/button/BootstrapBookmarkablePageLink.java
And this works just fine on my pc :)

Unknown tag name with Wicket namespace: 'panel'
I get an exception and it's not very clear to me what I'm doing wrong.
This is the exception:
Last cause: Unknown tag name with Wicket namespace: 'panel'. Might be you
haven't installed the appropriate resolver? '' (line 3,
column 2)
I'm trying to override the markupSourcingStrategy because i want this class
to have it's own html file. Anybody an idea? I use wicket-core 6.7.0.
This is my java file:
public class ExtBookMarkablePageLink extends BookmarkablePageLink {
private final Component label;
public ExtBookMarkablePageLink(String id, Class
pageClass) {
this(id, pageClass, new PageParameters());
}
public ExtBookMarkablePageLink(String id, Class
pageClass, final PageParameters parameters) {
super(id, pageClass, parameters);
add(label = newLabel("label"));
}
protected Component newLabel(final String markupId) {
return new Label(markupId, new
Model("")).setRenderBodyOnly(true);
}
@Override
protected IMarkupSourcingStrategy newMarkupSourcingStrategy() {
return new PanelMarkupSourcingStrategy(true);
}
public ExtBookMarkablePageLink setLabel(IModel label) {
this.label.setDefaultModel(label);
return this;
}
}
and this my html file:
http://wicket.apache.org";>
Re: documentation
Projects like Springframework use docbook. It's really nice, You put all documentation in xml files which are in the scm and when you release it, you have documentation per release.
