> Key: TAP5-1501
> URL: https://issues.apache.org/jira/browse/TAP5-1501
> Project: Tapestry 5
> Issue Type: Wish
> Components: tapestry-core
> Affects Versions: 5.2
> Reporter: Alex Lumpov
> Assignee: Howard M. Lewis Ship
> Fix For: 5.4

>
> 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).
> Hide uninteresting stack frames Stack trace
> Unable to locate asset 'classpath:mypackage/testapp/components/datefield.gif'

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