If you want to do it non the less, have a look at PageSource.getPage() to get an idea what needs to be done. However, it would probably make more sense to try and fit your initilization and destruction into the lifecycle of the tapestry objects instead of working around (and against) the framework. If you could be more specific about your real problem, it might be possible to show you an alternative.

Re: tapestry 4.0.2: How do I get a new page object?
You can instantiate a page by hand, but this will undermine the caching strategy of tapestry. My guess is, that you are better off rethinking your method of resolution. would you happen to know how i could achieve that? my requirement might not necessarily undermine tapestry's caching strategy - because all i want is a *different* instance of the page - if the page pool has another instance i could very well use it. it's just that i want to avoid using the same page object. any pointers would be most appreciated, thanks! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: tapestry 4.0.2: How do I get a new page object?
we have certain actions we perform in the tapestry lifecycle methods that are application-specific this is done both when a new page is created and before an existing page is retired to the pool now the problem is that when the same page object is returned, our retirement/creation logic is affected hence we're looking for a way to create a new instance of the page even though the cycle might already have instantiated the page once before Thanks, karthik On 4/16/07, Christian Haselbach <[EMAIL PROTECTED]> wrote: Quoting Karthik N <[EMAIL PROTECTED]>: > I have a requirement however where I want newPage to be a different > instance than this In that case you should probably rethink the requirement.

You could turn off the cache, but this is most certainly not what you want.

tapestry 4.0.2: How do I get a new page object?
Hi, While I am in a page "Page1" listener method and when I execute the following code: newPage = currentPage.getRequestCycle().getPage("Page1" ); I find that newPage and this page are both the same object i.e. System.out.println( newPage == this ); evals to true I have a requirement however where I want newPage to be a different instance than this Any ideas how this can be achieved? I looked up the documentation for this and found IPage getPage(java.lang.String name) Returns the page with the given name. If the page has been previously loaded in the current request cycle, that page is returned. Otherwise, the engine's page loader is used to load the page.
