I have my page in the package
xxx.pages
It does not matter if I put the abstract BasePage parent class to my page in
xxx.base or not. Tapestry complains about
BasePage: method <init>()V not found
If I add that constructor to my parent class the page works (almost)
as expected.
It gets even stranger since if I add the no-args constructor to the
abstract parent class but still invoke the parameterized constructor
in the parent class from the concrete page class it looks like it
doesn't set the property of the parent class.
So, is this expected behaviour?
Index.html (removed html header)
--------
<body>
<p>Superclass message set by constructor call from sub class:
${superclassConstructorMessage}</p>
<p>Superclass message set by setter in sub class: ${superclassSetterMessage}</p>
<p>Subclass message: ${subclassMessage}</p>
</body>
</html>
--------
Index.java
--------
package nu.zoom.web.reloaded.pages;
import nu.zoom.web.reloaded.base.BasePage;
public class Index extends BasePage {
private String subclassMessage;
public Index() {
super("Set from subclass by: super(\"Set from subclass by:
\");");
setSuperclassSetterMessage("Set in subclass by setter");
setSubclassMessage("Set by setter");
}
public String getSubclassMessage() {
return subclassMessage;
}
public void setSubclassMessage(String subclassMessage) {
this.subclassMessage = subclassMessage;
}
}
--------
BasePage.java
--------
package nu.zoom.web.reloaded.base;
public abstract class BasePage {
private String superclassConstructorMessage;
private String superclassSetterMessage;
public BasePage() {
super();
}
public BasePage(final String superclassConstructorMessage) {
super();
this.superclassConstructorMessage =
superclassConstructorMessage;
}
public String getSuperclassSetterMessage() {
return superclassSetterMessage;
}
public void setSuperclassSetterMessage(String superclassSetterMessage) {
this.superclassSetterMessage = superclassSetterMessage;
}
public String getSuperclassConstructorMessage() {
return superclassConstructorMessage;
}
}
