Re: Help with onActivate Page
2. If No, help me with the following scenario in my project.
I need to show a page a page to the user, only when it has a context with
it! Else i need to redirect the user to another page. Though i link the
page, only with the t:context, i just need to confirm no one has ever
bookmarked the page, and is seeing it.
Instead of using 2 onActivate() methods, you may also make use of
EventContext. It's often less verbose and better to read:
--
Object onActivate(EventContext eventContext) {
switch (eventContext.getCount()) {
case 0:
return NoContextPage.class;
case 1:
this.myparameterstring = eventContext.get(String.class, 1);
break;
}
}

Help with onActivate Page
Hello, I have a small doubt. I need some clarification regarding the onActivate() of every Page class.. 1. Is it Overloadable? (I know, it has some internal type casting, still wanted to know?) 2. If No, help me with the following scenario in my project. I need to show a page a page to the user, only when it has a context with it! Else i need to redirect the user to another page. Though i link the page, only with the t:context, i just need to confirm no one has ever bookmarked the page, and is seeing it. - Ashwanth Kumar
Re: Help with onActivate Page
What do you mean with overloadable? something like... a) void onActivate() b) void onActivate(String param) you mean that? I think the easier way is to do only one method: onActivate(EventContext context), tapestry5 will hit it always.

Re: Help with onActivate Page
Hi, You can have multiple event handler for the same event: http://tapestry.apache.org/tapestry5/guide/event.html The one with the same no. of arguments as the no. of context parameters will get called, as well as the no-arg one. I figured that out with my own experiment. Hope that helps. Kenneth 2009/12/27 Ashwanth Kumar ashwanth.ku...@gmail.com: Hello, I have a small doubt.
