As a follow up, I've created a very simple ajax page, included below.
I want the clear button to display an alert, and if they hit cancel,
stop the request. This does not happen even with this trivial example.
The onClear will be called regardless of what button is clicked. This
fails under IE, FireFox and Safari.
// Test.java
package com.myasd.www.obit;
import org.apache.tapestry.IExternalPage;
import org.apache.tapestry.IRequestCycle;
import org.apache.tapestry.annotations.Persist;
import org.apache.tapestry.html.BasePage;
public abstract class Test extends BasePage implements IExternalPage {
@Persist("session")
public abstract String getTest();
public abstract void setTest(String in);
public void activateExternalPage(Object[] parameters, IRequestCycle
cycle) {
setTest("activateExternalPage");
}
public void onQuery() {
System.out.println("On Query!");
setTest("onQuery");
}
public void onClear() {
System.out.println("On Clear!");
setTest("onClear");
}
}
