Message page

[Koen Segers <Ko...@scarlet.be>]

Hi,

Lots of pages contain simple messages as "Welcome X, " after successfull 
login. Therefore I believe it would be nice to have a page Message that has a 
Insert component one can set when a form is completed.
The question is how can I set the string of that component so that when 
redirecting to that page the correct string is showed?

This is what I have:
IPage page = cycle.getPage("Message");
Insert messagecomp = (Insert)page.getComponent("message");
messagecomp.setProperty("value", "Welcome, "+userName);
cycle.activate(page);

But the message component still stays empty.
What have I done wrong?

A couple of things I see right off. First is that your casting as IPage. 
Does IPage have a message component? It has a message property, but the 
IPage interface doesn't have a Message Component.

Second, if you want to get a use a page, cast to that page:
Message page = (Message)cycle.getPage("Message");

That way you can get completion and type checking in your IDE, as well as 
more compile-time checking.

Finally, what I would do is have a property on my base page for the message 
(be careful, getMessage() is built in to Tapestry's BasePage!). This 
property would take a string. Then if the string isn't null or empty, 
display your Message component when the page renders (this would go in your 
Border component).
