RE: urgent: access a spring bean from a service encoder?
The important thing to keep in mind is that the "object" parameter to the "encoder" element is a hivemind reference, which means it can be a reference to another hivemind service, or to a spring service. or You can configure those beans in the usual way.

Re: want external link to cause cycle.forgetPage() behaviour
https://issues.apache.org/jira/browse/TAPESTRY-1116 On 10/20/06, Sam Gendler <[EMAIL PROTECTED]> wrote: I've got a CSS menu bar on my pages. I want the links in the menu to use ExternalLink so that they are bookmarkable. I can't have the link submitting back to a listener method in my shell component, beacuse then the URL is always one page behind the page I am actually looking at, since the parameters in the URL will have the page name/component name of the PREVIOUS page. Many of the pages accessed via the menu have tables on them which are derived from contrib:table, meaning that the state of the table pages and sorted column are kept in the session. When accessing a page via the menu, I always want the page to be in its default state. I only want the table state to be retained when accessing the page via other links, never the menu. I can't easily just reset all the values in activateExternalPage because many of the persistent properties are actually part of components nested several levels deep within the page. Calling cycle.forgetPage() would ordinarily be enough to blow all the stored state about any component in the page out of the session (I assume that's what it does, anyway). So I tried adding a parameter to the service parameters that get passed to activateExternalPage(). If I get a reset param, then I call cycle.forgetPage(getPageName()); This mostly works - however, because activateExternalPage is called AFTER the page is attached, it has already been populated with values from the session, so after activateExternalPage runs, the page displays with its stored state. Then, if I hit reload, the page gets a new instance form the page cache, and this time the session has been cleared of all data BEFORE the page was attached, so now it displays in its default state. So then I tried calling cycle.forgetPage() and then created an ExternalCallback to the current page, this time without the reset parameter, since the page has already been reset. I then call performCallback on the callback, to try to get an instance of the page to run which is populated after the call to forgetPage(). In my logs, I can see activateExternalPage getting called twice, but the second one still has the saved state. The only way to get the reset to actually show up is to reload the page - basically, it appears to require a new request cycle in order to forget a page.

Re: RE: RE: Recovery of session during pageValidate
Thanks Jeff. Shawn, I assume your email response to me crossed paths
with Jeff's, but if not, I'd look pretty carefully at his solution.
It is a more heavyweight solution than I'm sure any of us want, but it
will definitely get the job done and doesn't look like it would be too
hard or time consuming to implement.
I'll probably do it myself when I get a chance. If you like, I'll
post my code here when I'm done, but I can't say when that will be.

Re: Recovery of session during pageValidate
It's nice to at least know you've had the same problem. Your code below
represents exactly what I'm after, but I so far haven't found any
practical way to make it work. I've tried things like creating my own
POST (using HttpClient) within the current request cycle, but dealing
with this "inner" response while servicing the original response is
pretty messy and generally involves a bad hack to the Tapestry request
cycle. Hopefully someone else already has a solution, but otherwise I
plan to come up with something more graceful than a "sorry, I'm too
stupid to service your request" page.
Thanks,
Shawn

want external link to cause cycle.forgetPage() behaviour
I've got a CSS menu bar on my pages. I want the links in the menu to use ExternalLink so that they are bookmarkable. I can't have the link submitting back to a listener method in my shell component, beacuse then the URL is always one page behind the page I am actually looking at, since the parameters in the URL will have the page name/component name of the PREVIOUS page. Many of the pages accessed via the menu have tables on them which are derived from contrib:table, meaning that the state of the table pages and sorted column are kept in the session. When accessing a page via the menu, I always want the page to be in its default state. I only want the table state to be retained when accessing the page via other links, never the menu. I can't easily just reset all the values in activateExternalPage because many of the persistent properties are actually part of components nested several levels deep within the page. Calling cycle.forgetPage() would ordinarily be enough to blow all the stored state about any component in the page out of the session (I assume that's what it does, anyway). So I tried adding a parameter to the service parameters that get passed to activateExternalPage(). If I get a reset param, then I call cycle.forgetPage(getPageName()); This mostly works - however, because activateExternalPage is called AFTER the page is attached, it has already been populated with values from the session, so after activateExternalPage runs, the page displays with its stored state. Then, if I hit reload, the page gets a new instance form the page cache, and this time the session has been cleared of all data BEFORE the page was attached, so now it displays in its default state. So then I tried calling cycle.forgetPage() and then created an ExternalCallback to the current page, this time without the reset parameter, since the page has already been reset. I then call performCallback on the callback, to try to get an instance of the page to run which is populated after the call to forgetPage(). In my logs, I can see activateExternalPage getting called twice, but the second one still has the saved state. The only way to get the reset to actually show up is to reload the page - basically, it appears to require a new request cycle in order to forget a page. Is there some other way around this? --sam - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Recovery of session during pageValidate
I'm hoping to find a better way to handle expired sessions without redirecting to a default page. I have many users which tend to let sessions time out over lunch or over night, but who expect to be able to resume working at any time without losing form data, etc. I have a typical "protected" base page which implements PageValidateListener. If no Visit object exists, my current implementation captures the full request URL and parameters (via getHttpServletRequest().getParameterNames()), stores them in the (newly created) Visit object, redirects to my authentication server (which redirects back upon successful authentication), and then services the original request by redirecting to the previously stored URL. The problem is that I often exceed the max GET request length, since I am having to encode form post data in the URL. Does anyone know of a way to capture post data during pageValidate so I can eventually (upon completion of validation and visit creation) serve the originally-requested page without losing form posts? Even though I can't in this case remain completely stateless, I would like to be able to gracefully recover the expired session state and continue without interruption (or loss of user form data). Everything is working fine now, except in the case where the URL request length exceeds the browser maximum. I would really like to be able to inject the previously stored request parameters into the Tapestry request cycle, and then continue with a normal cycle.activate(). I would greatly appreciate any help, since this problem is very common among a dozen or so applications I have running in this environment (Tapestry 4).

Re: How can I do custom Exception page in tapestry portlet?
I have a follow-on question. For most every thing I have found I don't need a .page or .jwc file at all. However, for some cases like this I do (the other is changing the default Home location). But the .page file is pretty empty. Is there away to avoid having to have this empty .page file? -Pat - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: How do I override the stale session and links pages
Nevermind, looks like Andreas and Thomas answered your question. Although I have to say that overriding the page names in your hivemodule file seems like a cleaner approach than "hiding" the default pages in your .application. My guess is that you were running into a page resolution issue in your first attempt and Tapestry couldn't find your custom pages (?). I'll find out for myself soon enough since I have to do the same thing in a week or two... -Ryan On Oct 19, 2006, at 9:08 AM, Mats Henricson wrote: Hi!

Re: How do I override the stale session and links pages
The default StaleLink page extends BasePage, so you shouldn't have to extend a special base class. However, the default StaleLink page class declares a "message" property (i.e. public abstract void setMessage(String message)), so your custom page probably needs the same thing. There doesn't appear to be a specific StaleSession page class in Tapestry, so I'm not sure why yours isn't working. If you can provide more details on the error you are seeing, maybe I can help. -Ryan On Oct 19, 2006, at 9:08 AM, Mats Henricson wrote: Hi!

IRoleServiceRemote iRoleServiceRemote = (IRoleServiceRemote)
initialContext.lookup("app/RoleService/remote");
return new RoleSelectionModel(iRoleServiceRemote.findAll());
}
public void addRolAction() throws Exception {
getUser().getRoles().add(new Role());
}
...
public void submitAction() throws Exception {
// after add one role the user property have 1 role
// but data are not initialized
for (Rol role : getUser().getRoles()) {
System.out.println("id: " + rol.getId());
System.out.println("name: " + rol.getName());
}

private List roles;
public RolSelectionModel(List roles) {
this.roles = roles;
