Description

I get an exception in case of the following simple page:

package test;

import org.apache.tapestry.IComponent;

import org.apache.tapestry.annotations.InitialValue;

public abstract class Home extends BasePage

{

public static class A

{

public A(IComponent component)

{

}

}

@InitialValue("new test.Home$A(#root)")

public abstract A getA();

}

The stack trace:

2007.06.11. 7:59:09 org.apache.tapestry.services.impl.HiveMindExpressionCompiler compileExpression
