Problem #1 is gone.

But problem #2 is still there.


Tested with 1.2-20060216 from sourceforge and head of main trunk CVS.

1.2 HEAD. 1.2 just removes the markup from the cache without trying to
reload it. It is reloaded the next time the resource is requested.

I have set up my wicket application to reload constantly mytemplates:
public class MyWebApplication extends WebApplication {
    public MyWebApplication() {

getSettings().setResourcePollFrequency(Duration.ONE_SECOND);

        getPages().setHomePage(Index.class);
    }
    protected void init() {

getSettings().addResourceFolder("/java/myapp/templates");

    }
}

And this works excerpt for two problems:

1. (After more than one deployment using Tomcat Manager). Thelog of my

Apache Tomcat is filled with this every second:

2. If a make the following spelling mistake:

<html>
<body>
<div id="Header" wicket:id="header">
</div>
</body>
</html>

  ---->

<html>
<body>
<div id="Header" wicketxxxx:id="header">
</div>
</body>
</html>

It will fail with:

wicket.WicketRuntimeException: The component(s) below failed torender

...

However it will not reload if I correct it back again.Correction is

only

effective if I redeploy.

Any solutions?

I am using wicket 1.1.1 - should I try another version?
