Ok, it's a little complicated to create the metadata
If I'm rigth, the process is - for example when click on an AjaxLink into the
page
1- Execute the method onClick of the AjaxLink
2- Send an event to all the components of the page (the page itself included,
on first place, but not other pages ?),
- The source of the event is the page itself
- The type of broadcast is BREADTH
- The payload is the AjaxRequestTarget (from the onclick method call)
/******** EXAMPLE OF DATA ************/
public class MyEventData {
static MetaDataKey<MyEventData> METAKEY_MYEVENTDATA = new
MetaDataKey<MyEventData>(){};
String s = "";
public MyEventData(){}
public MyEventData(String s) {
this.s = s;
}
public MetaDataKey<MyEventData> getWicketMetadataData(){
// A little complicated
MetaDataKey<MyEventData> key = new MetaDataKey<MyEventData>(){};
MetaDataEntry<MyEventData> metaDataEntry = new
MetaDataEntry<MyEventData>(key,this);
MetaDataEntry<MyEventData>[] arrayMetaDataEntry = new
MetaDataEntry[]{metaDataEntry};
key.set(arrayMetaDataEntry,this);
return key;
}
public void setIntoRequest(RequestCycle rc){
rc.setMetaData(getWicketMetadataData(),this);
}
public static MyEventData getFromRequest(RequestCycle rc){
return rc.getMetaData(METAKEY_MYEVENTDATA);
}
}

Maybe RequestCycle#setMetaData might be useful for that.
