I just solved a problem where I used a headercontributor (following Eelco's blog http://chillenious.wordpress.com/page/2/) using
add(HeaderContributor.forJavaScript (getClass(), "script.js"));
On some pages it turned out that this same resource was included twice with different URLs. What happened was that I used
new MyComponnt(parent, id) {
public void isRequired() {
return true;
}
};
Effectively creating a new component referring to the same resource.
The problem was solved by using MyComponent.class instead of getClass(0 in the component implementation. Shouldn't the javadocs say something about this that it is advised to use MyComponent.class instead of getClass() to avoid multiple inclusion of the same resource?
Cheers
Erik
