Description

Suppose there is a component that uses a certain asset (for example DateField). I want to extend it.
For example:

package mypackage.testapp.components;
import org.apache.tapestry5.corelib.components.DateField;
public class MyDateField extends DateField {
}

If i change the asset and put it in a new classpath, then everything is fine.
But if i want to override only a class and use the already existing asset, then i get the error:

Unable to locate asset 'classpath:mypackage/testapp/components/datefield.gif' (the file does not exist).

It seems to me it would be nice if the classpath assets could be inheritable like templates.
