RPC/Serialization problem with StockWatcher tutorial

2009-06-03 Thread james.o...@gmail.com 

I'm going through the StockWatcher tutorial and I get to the RPC part
(http://code.google.com/webtoolkit/tutorials/1.6/RPC.html).

At the first test point I get this error message as expected ...

 [ERROR] Type 'com.google.gwt.sample.stockwatcher.client.StockPrice'
was not serializable
 and has no concrete serializable subtypes

However, after putting in the code to fix it ... I still get the
same error.  What am I missing?

Here is my StockPrice class ...

package com.google.gwt.sample.stockwatcher.client;

import java.io.Serializable;

public class StockPrice implements Serializable {
private String symbol;
private double price;
private double change;

public StockPrice(String symbol, double price, double change) {
this.symbol = symbol;
this.price = price;
this.change = change;
}

public String getSymbol() { return this.symbol; }
public double getPrice() { return this.price; }
public double getChange() { return this.change; }

public double getChangePercent() {
return 100.0 * this.change / this.price;
}

public void setSymbol(String symbol) { this.symbol = symbol; }
public void setPrice(double price) { this.price = price; }
public void setChange(double change) { this.change = change; }
}

Your StockPrice doesn't have a no-arg constructor.

Thanks!  I guess I missed that line earlier in the tutorial.
