is it possible to include script resources using the HeaderContributor above the WebPage component script references

2009-08-31 Thread Joe Hudson 
Hello, I would like for the script included using a HeaderContributor to be 
above script references within the WebPage component head node.  Is this 
possible.  The reason I would like to do this is because I would like to be 
able to reference code from the script file which is included using the 
HeaderContributor.  For example:

--- Application class ---
// inside init method
addComponentInstantiationListener(new IComponentInstantiationListener() 
{
public void onInstantiation(Component component) {
  if (component instanceof WebPage) {
component.add(new HeaderContributor(new 
IHeaderContributor() {
  public void renderHead(IHeaderResponse response) {
response.renderJavascriptReference(new 
JavascriptResourceReference(MyReferenceClass.class, scripts/example.js));
  }
}));
  }
}
});

// WebPage component template
head
  script type=text/javascript
...
// I can't reference anything from the scripts/example.js because 
the source reference appears below this in the rendered output
/script
/head

By the way, please tell me if this is bad code and there is a better way as I 
am very new to Wicket.  All code criticism is welcomed :)

Thanks.

Joe, an diferent option is create a custom WebPage with all needed resources
to serve as super class for all web pages class of your application.

Html for super class:
html 
head
wicket:link
  script type=text/javascript src=scripts/example.js/script
/wicket:link
/head
body
wicket:child /
/body
/html

and for subclasses

head
/head
body
wicket:extend
  !-- page code --
/wicket:extend
/body
/html
