I think this may work (as a workaround at least): public class Start { private Integer _result; public Integer getResult() { return _result; }
public void setResult(Integer result) { _result = result; } Integer onPassivate() { return _result; } Object onActivate(Integer result) { _result = result; if(result != null) return null; // continue activating the page with context else return Start.class; // since the context is invalid, return the page without context. This may happen automatically if you just change the int to Integer and leave this method untouched, but I'm unsure. } } Peter Beshai On Thu, Apr 3, 2008 at 6:25 AM, dhning <[EMAIL PROTECTED]> wrote: > Hi, > > I get a intersting problem: > > Start.java: > public class Start > { > private int _result; > public int getResult() { > return this._result; > } > > public void setResult(int result) { > _result = result; > } > int onPassivate() { > return _result; > } > void onActivate(int result) { > _result = result; > } > } > > Start.tml > <html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd"> > <head> > <title>t5first Start Page</title> > </head> > <body> > <h1>t5first Start Page</h1> > > <a href="#" t:type="actionlink" t:id="view">View</a> > > </body> > </html> > > Steps: > When inputting url such as /t5start/start, no problem.
