are all of the right type.. Else you will get a class cast exception.
Reflection will not convert from one object to the other.
PropertyResolver is using the given converter for that.

fillParameters should have looked like this
private Object[] fillParameters() {
Object param[] = new Object[parameters.size()];
for (int i = 0; i < parameters.size(); i++) {
Object[] params = (Object[]) parameters.get(i);
Class clazz = (Class) params[0];
param[i] = ((IModel) params[1]).getObject(null);
}
return param;
}

Subject: [Wicket-user] wicket.util.lang.PropertyResolver / migth be a littleofftopic
Hi
I need to do something similar as the propertyresolver does. Therefore im writing to the wicket userlist.
I have a component that can update a list of other components by a ajax call. This component also fills out a palette(something similar to the extension.palette).
It gets the value by calling a method which were provided and the required parameters was also provided, it does this by using java.lang.reflect.Method.
In my effort on trying to make this a bit more generic component I was trying to have an arraylist which contained class's and IModels.
Setting up the method was fine and simple enough, currently im stuck when trying to build the list of parameters im wondering if I have to typecast the parameters at all or if reflection will handle that, because of what I did in the setupMethod method, I am betting the latter?
//sniplet
private void setupMethod(Object myProvider, String sMethod) {
Class partypes[] = new Class[parameters.size()];
for (int i = 0; i < parameters.size(); i++) {
Object[] params = (Object[]) parameters.get(i);
partypes[i] = (Class) params[0];
}
Method method;
try {
method = myProvider.getClass().getMethod(sMethod, partypes);
} catch (Exception e) {
…
}
this.dbprovidermethod = method;
}
private Object[] fillParameters()
{
Object param[] = new Object[parameters.size()];
for (int i = 0; i < parameters.size(); i++) {
Object[] params = (Object[]) parameters.get(i);
Class clazz=(Class) params[0];
param[i] = (clazz) params[1];
}
return param;
}
//sniplet
