if you use directLink, you can pass parameters to listener method in
the page/component where the link is generated from.
in the listener method, you get a page instance of another page by
calling requestCycle.getPage(...).
you can then cast the IPage you have to the instance of the Page class
you know it is, and set some properties, for example the id you passed
to the listener.
I assume you use 4.0 : on the target page, implement the validate method
(pageValidate() ? - look at the docu for exact name), to check that the
needed property is set. if not, throw a PageRedirectException.
Hope that helps,
Cheers,

Hi,
Let me put down what I am trying to do so that the problem can be better understood.
I am trying to create a login screen which leads to a second page which lists out some values read from a ‘.properties’ file. Now I want that the read values should be displayed as a link which when clicked should be directed to a third page which again displays a list of items read from an ‘.xml’ file.
I want that when the link is clicked a unique id be passed on to the third page so that I can use it for certain operation in it.
The entire thing needs to be done in tapestry.
Things I have tried out.
I am done with the login screen. Its working fine.
I have also been able to create the links
I extended the AbstractComponent class to define the component used to display the links. The renderComponent(IMarkupWriter writer, IRequestCycle cycle) method was overridden to render the component.
Problems that I am facing is
Once I am clicking on the link and going to the third page am not able to display any of the user defined components.
But if I am trying to display the same component at a go (i.e.
without any kind of interaction with the UI) it’s working fine.
How to capture the data sent from the second page in the third page.
If needed the sample code written can be provided.
