Description

The following page works as expected:

package test;

import org.apache.tapestry.annotations.Component;

import org.apache.tapestry.annotations.InitialValue;

import org.apache.tapestry.components.Insert;

import org.apache.tapestry.html.BasePage;

public abstract class Test extends BasePage

{

public static class IntWrapper

{

public IntWrapper(int value)

{ this.value = value; }

private final int value;

@Override

public String toString()

{ return Integer.toString(value); }

}

@InitialValue("2")

public abstract int getValue();

@Component(bindings = "value=new test.Test$IntWrapper(2)")

public abstract Insert getInsert();

}

After the following modification it fails:

@Component(bindings = "value=new test.Test$IntWrapper(value)")

The exception:
