Re: running example

[Alex Kravets]

thanks Geoff,
So the example was wrong then? And as I understand when I define a 
binding with name listener it will always be put into map by Tapestry?

and the java to:

  public void okListener(IrequestCycle cycle) {
cycle.activate("Result");
}
}
  

IActionListeners are create for you by Tapestry and hooked to the
methods with sigs as above. These synthetic listeners are stored in a
map called "listeners" hence the ognl expression
"listeners.okListener".

change:
<binding name="listener" expression="okListener"/>
to:
<binding name="listener" expression="listeners.okListener"/>

I am experimenting with currency converter from this tutorial:
http://www2.cpttm.org.mo/cyberlab/softdev/tapestry/ .
When I run application I get an exception:
org.apache.tapestry.BindingException

I have all the files as in tutorial, but have no idea what's going on.
Obviously it can't link Home.page with Home.java, but why?
