Broken response encoding of exception page

[Holger Stolzenberg <h....@ewerk.com>]

Hy there,


Yes I know I have posted about this problem earlier in this thread but our project will end soon and the problem still is present:

The problem is that the output encoding of the exception page rendered by the ExceptionPresenter is broken. Following situation (code below):

When an exception occurs in a listener method, we catch it and throw a PageRedirectException to the err page of our application. Everything is fine. But when the exception occurs in the getModel() method (e.g. when the page is initially called), the PageRedirectException thrown is wrapped into a BindingException. This exception goes further on and is handled by the tapestry exception presenter. 

I have taken the source of the tapestry exception presenter and implemented an custom class. Then I configured hivemind to use this custom exception presenter (via infrastructure overrides). The code og the custom exception presenter is 100% the same to that of Howard I only put some debug output to it before responseRenderer.renderResponse( cycle ) is called.
	
	ContentType type = errPage.getResponseContentType();
	
	System.out.println( "1> " + cycle.getEngine().getOutputEncoding() );
	System.out.println( "2> " + type.getParameter( CHARSET_PARAM_NAME ) );

	CONSOLE-OUTPUT:
		1> UTF-8
		2> null
		
The BindingException now handled by the custom ExceptionPresenter (or the tapestry ExceptionPresenter, which makes no difference) renders the ErrPage. Problem is that this this ErrPage is not rendered in UTF-8. It is rendered in ISO-8859-1, so all german special chars are broken, which means a really ugly picture on the browser, because we do not use @Shell component and output encoding 
	
	<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />

is hard coded in HTML Template.

Any ideas where to go????

-------------------------------------------------------------

(1) Page spec
<page>
	...
	
	<component type="PropertySelection">
		<binding name="model" value="getModel()" />
	</component>

	...
</page>

-------------------------------------------------------------

(2) In Java class

public void someListener()
{
	try
	{
		// do something
	}
	catch( Exception e )
	{
		ErrPage errPage = getErrPage();
		errPage.setErr( e );

		throw PageRedirectException( errPage );
	}
}

@InjectPage( "ErrPage" )
public abstract ErrPage getErrPage();

public IPropertySelectionModel getModel()
{
	try
	{
		// init and return model
	}
	catch ( Exception e )
	{
		ErrPage errPage = getErrPage();
		errPage.setErr( e );

		throw PageRedirectException( errPage );
	}
}
