How to modify attribute (eg. class) in component with setRenderBodyOnly(true) ?
Hi, Is it possible to modify tag attribute (eg. add a CSS class) of component which has set renderBodyOnly flag to true? When using component.add(new AttributeModifier(...)) it has no effect, because a tag in which this class attribute is appended is not rendered in HTML (because of setRenderBodyOnly(true)). Here is an example: LinkContainer is a component (extends Panel) which has setRenderBodyOnly(true). wicket:panel a wicket:id=linkwicket:container wicket:id=linkContent[link content]/wicket:container/a /wicket:panel Somewhere inside a page or panel: add(new LinkContainer(link, ...).add(new AttributeModifier(class, Model.of(my-link-style; But of course this class='my-link-style' will not be rendered anywhere. I want to add a class attribute to contained a tag but using a behavior which can be added to the whole LinkContainer. Is it any simple solution to achieve this? -- DS - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: How to modify attribute (eg. class) in component with setRenderBodyOnly(true) ?
Hi, So you want to not have a (because this is what .setRenderBodyOnly(true) does) and in the same time you want to set a class an that non-existing tag ?! The easiest way is to remove the call to .setRenderBodyOnly(true).

No. I want to have a. When you use this LinkContainer from my example in HTML like: div wicket:id=link /div It will be rendered as: a wicket:id=link.../a So any attributes modified using behavior will disappear. But if LinkContainer will not have setRenderBodyOnly(true), the the corresponding HTML will be: div wicket:id=link class='my-link-style' a wicket:id=link.../a /div -- DS On Wed, Feb 22, 2012 at 11:49 AM, Martin Grigorov mgrigo...@apache.org wrote: Hi, So you want to not have a (because this is what .setRenderBodyOnly(true) does) and in the same time you want to set a class an that non-existing tag ?!

No.
To add the AttributeModifier to the Link I have to write extra method
inside a LinkContainer which adds a behavior to enclosing component
(Link is created inside LinkContainer and because of ecapsulation it
should not be visible outside it). But the cleaner solution will be to
add a behavior to LinkContainer, but then it should be transparently

To which child exactly ? How to decide that for you ?
Then I can use AttributeModifier (or related behaviors) the same way
with component which has setRenderBodyOnly(true) or not. But now I
need to know a component implementation to decide if I can use such
modifiers with it or no.
Each behavior has a reference to the component it is bound to. So you
can assign your own Behavior to the parent class and then in
behavior's onComponentTag, renderHead(), ... you can do whatever you
need with the parent and all its children. It is a bit harder to get
the children ComponentTags but it is possible: new
MarkupStream(getMarkup()) and iterate over the elements in the
MarkupStream.
Thanks for your feedback and suggestions.
I have done a simple behavior to achieve what I want. Maybe this is
not very elegant solution but it should work. It writes out attributes
added as AttributeModifiers to a parent component to a child component
which has this behavior.
public class AttributeModifierPropagator extends AbstractBehavior {
private final MarkupContainer parent;
public AttributeModifierPropagator(MarkupContainer parent) {
super();
if (parent == null) {
throw new IllegalArgumentException(Argument [parent] cannot be null);
}
this.parent = parent;
}
@Override
public void onComponentTag(Component component, ComponentTag tag) {
for (IBehavior behavior : parent.getBehaviors()) {
if ((behavior instanceof AttributeModifier) || (behavior
instanceof SimpleAttributeModifier)) {
behavior.onComponentTag(component, tag);
}
}
}
}
And then inside a LinkContainer after creating nested Link link I can
add this behavior to it:
link.add(new AttributeModifierPropagator(this));
