Re: [Wicket-user] VOTE on wicket:component
As a long-time Tapestry user (but very new Wicket user), I have a few thoughts about in-line component declaration. 1.) Even in a framework like Tapestry where the idiom is fully supported, it can lead to complex and difficult to maintain templates. In fact, it's generally discouraged in Tapestry for those reasons. 2.) Providing a fundamentally different, optional way to declare components in Wicket seems more like an unnecessary increase in ways to do it rather than a useful increase in flexibility. 3) The tooling support issue should not be underestimated. The author of the Spindle plugin for Tapestry eventually gave up on updating it for Tapestry 4 precisely because there were so many ways in which components could be defined (in the template, in the XML spec file or in Java via annotations). While experienced Tapestry users can get along just fine without that plugin, it was a big selling point for new users. In short, I think you should hold a hard line against increased functionality in templates and only make exceptions for the most compelling and common use cases (e.g. wicket:message). -Ryan On Feb 13, 2007, at 8:47 AM, Jonathan Locke wrote: Our Wiki describes the wicket:component tag as follows: wicket:component - Creates a Wicket component on the fly. Needs a class attribute. Though this has been in wicket for a long time, it is still kind of an unsupported feature, as most of the core developers believe that this may lead to misuse of the framework. Before heavily relying on this feature, you might want to contact the user list to discuss alternative strategies. It's unclear to me that anyone is using this. The utility is limited and unimportant. And for anyone creating tooling support for wicket, this will be a tripping point. I can't see any good reason to keep this feature as it is a way to instantiate a component in the markup and might server as the beginning of a bunch of requests to add component configuration or other code logic where we should only have nice clean markup.

Re: [Wicket-user] multiple rendering at same time
It sounds like Scott just wants to allow the user to cancel the

request happened in a LoadableDetachableModel rather than a page
constructor, would that allow a new page to be rendered while the old
one is still trying to load data?

No, that doesn't make a difference. Detachable models can be used to limit the amount of data that is cached as 'component state' between requests, and to ensure that new requests are done with fresh data. The rendering of pages stands apart from that. If you want to break up a request in multiple parts - which is what you want to do here, as you first want to show the page without the data, possibly with some kind of place holder for the data or e.g. a progress indicator - you can best use Ajax or, second best, use (i)frames and resources. If you use Ajax, it's best to do the processing in a separate thread and let Ajax do polling as that won't block the session. Which reminds me of something I wanted to investigate concerning stateless behaviors (for ajax). But I'll start another thread about that. Eelco - Take Surveys. Earn Cash.

Re: [Wicket-user] multiple rendering at same time
Ahh, I think we discussed this earlier. The best solution are to utilize a
worker thread (I think) and make the client reload until the thread are done..
I think it's essential for wicket in order to handle session state to use a
singleton pattern for request cycles.
EG if page A have long loading time page b,c,d will just have to wait. So if
you utilize a worker thread then you will be able to cancel the thread and go
to the other page if you want to.

Re: [Wicket-user] multiple rendering at same time
Thanks, that really clears it up. At first glance, synchronizing pages on the session seems a little overly restrictive (Scott's issue being a case in point), but of course *not* synchronizing on the session is an infamous source of frustrating bugs, even in frameworks with much simpler state handling than Wicket. Very cool, I would much rather have to intentionally enable multithreaded operations on a case-by-case basis than have to constantly worry about subtle multithreading issues. -Ryan On Feb 14, 2007, at 1:54 AM, Eelco Hillenius wrote: On 2/14/07, Ryan Holmes [EMAIL PROTECTED] wrote: It sounds like Scott just wants to allow the user to cancel the slow-loading page by navigating to another page.

[Wicket-user] second level cache - why not to use ehcache
I looked at pages second level cache implementation in 1.3 and wonder why not to use ehcache instead? It's much more intelligent, configurable and performant.

[Wicket-user] AjaxFallbackDefaultDataTable (2.0) - how to update table when item is added or deleted
Hello, I know that there must be an easy way to do this, but I have not been able to figured it out os far, and there are no examples that I could find. I would like to know how you can update the AjaxFallbackDefaultDataTable in 2.0, when the underlying data has changed, such as in a delete or add operation. So far I have tried updating the table through the standard target mechanism we use for other AJAX components in Wicket, however no joy so far. I have also tried calling the modelChanged() method on the table, still no effect. I could replace the whole table, but that seems a bit draconian, and would defeat the purpose of using AJAX in the first place. The only thing I have not tried is targeting each column of the table individually. Thanks in advance for all assistance.

Re: [Wicket-user] AjaxFallbackDefaultDataTable (2.0) - how to update table when item is added or deleted
you have to update the whole table. there is nothing draconian about it because any other row may or may not be there after the update - other users might be adding/removing things to the table as well. -igor On 2/14/07, De Soca [EMAIL PROTECTED] wrote: Hello, I know that there must be an easy way to do this, but I have not been able to figured it out os far, and there are no examples that I could find. I would like to know how you can update the AjaxFallbackDefaultDataTable in 2.0, when the underlying data has changed, such as in a delete or add operation. So far I have tried updating the table through the standard target mechanism we use for other AJAX components in Wicket, however no joy so far. I have also tried calling the modelChanged() method on the table, still no effect. I could replace the whole table, but that seems a bit draconian, and would defeat the purpose of using AJAX in the first place. The only thing I have not tried is targeting each column of the table individually. Thanks in advance for all assistance.

[Wicket-user] Form submitted normally and via AJAX? (Wicket 1.2.5)
Hi all, In my Databinder-using application I have the requirement to create/edit entities both within a standard request cycle, and via AJAX inside a Modal Window. In the interests of not duplicating code, I would like to drive both these processes from the same Form object, passing a boolean from the page to tell the Panel containing the Form whether it's submitting normally or via AJAX. I have run into the following problem: The AJAX submission is via an AjaxSubmitButton. This Component calls the Form's onSubmit/onError methods before calling its own methods. This means I cannot include any code specific to one method of submission in the Form's onSubmit/onError methods. Because of this, for a standard submission I use a Button with defaultFormProcessing set to false and an overridden onSubmit method. But the Button has no onError method, so I cannot provide any standard-submission-specific error-handling code if the same object is to handle an AJAX submission. Does anyone have any suggestions on how to get around this? At the moment I'm attempting to step around the issue by duplicating all submission-processing code the page via an anonymous subclass of the Panel/Form object, but I would appreciate a better solution if anyone knows of one!

The utility is limited and unimportant. And for anyone creating tooling support for wicket, this will be a tripping point.

[Wicket-user] custom serialization problem

Re: [Wicket-user] second level cache - why not to use ehcache
Its EXACTLY a cache What isn't a cache is ehcache At least not in my point of view A cache is something you cache something as good as you can but it can be gone at anytime. ehcache is not a cache. Its a in memory predefined size list. where some can drop of and others not thats not caching. Thats pooling And the current caching is because we don't version anything anymore in the undo buffer doesn't make much sense. Except if you really make new pages again for pretty much all the clicks/navigation that you do. Maybe we should cache the byte[] instead of the pages. What would cost more? Because now if you are on page X version 0 and you click and you go to Page X version 1 then go back.. Previously this was really still an in mem operation. Nowadays it is always a read from disk.. maybe we should change that and i am completely not suprised that ehcache was not performing better. How could it do that?? Where should the gain come from? The current impl really grows directly with the hardware you have. ehcache need to be tweaked exactly what your system can handle. What do you say then? 200 page? 2000 pages?

yes the error reporting must be done better. But your catch that it doesn't release the lock is a good one will check that out.

Re: [Wicket-user] second level cache - why not to use ehcache
But cache is for caching things that are expensive to get, but when they are evicted from cache, they can be restored. When you remove wicket page (or better said page version) for wicket 2nd level store, it can not be restored. As for performance, the gain could be in finer grained synchronization, as imho currently the synchronization is the bottleneck. -Matej Johan Compagner wrote: Its EXACTLY a cache What isn't a cache is ehcache At least not in my point of view A cache is something you cache something as good as you can but it can be gone at anytime. ehcache is not a cache.

Re: [Wicket-user] tons of size of failed exceptions
Well, I was using a release from the previous days and that is why it wasn't swallowing the Exception (I have since verified that I am using the latest SNAPSHOT from source, not wicketstuff repo). But I still experience HUGE delays when it goes wrong (I just can't see why now, which is actually worse than before because at least I could see why that app ground to a halt) I had one bog down for 59 seconds today. My average seems to be between 20-30 seconds. I guess maybe the question might be will http://issues.apache.org/jira/browse/WICKET-278 potentially solve the problem by eliminating the Exceptions or is their another issue that causes the slowdown and #278 is just one way to repeatedly cause the problem?

My real concern (besides all of the crap that is spewed into my log, obscuring the real exception) is the time it takes to do this: from the timestamps you can see that this takes roughly 21 seconds! I guess my argument would be that if I received the first exception then of course something is screwed up, so why bother continueing whatever processing that is going on that causes at wicket.util.lang.Objects.sizeof(Objects.java:1281) at wicket.Component.getSizeInBytes(Component.java:1107) at wicket.markup.html.debug.PageView$3.component(PageView.java:140) to be called. It looks like some attempt to serialize but, if I got the first exception, what cause would there be to serialize anything? Is this a work in progress type of thing or unexpected behavior? The NotSerializableExceptions gets swallowed silently in that function since yesterday (which is in line with how it was implemented for 2.0). Why it takes so long? I have no idea unless you are working with huge components. Even then 21 seconds sounds like something definitively being wrong. Eelco - Using Tomcat but need to do more?

Re: [Wicket-user] second level cache - why not to use ehcache
Everything can be restored.

Hibernate's Session is serializable but it depends on what's in it obviously. But why would you want to keep the session as a page var anyway? I think it's better to use e.g. that hibernate filter that sets in it the threadlocal for the request (and cleans it up afterwards) and access that threadlocal when you need it. Much cheaper.

Re: [Wicket-user] second level cache - why not to use ehcache
i wonder if it wouldn't pay to stop and refactor this a little. besides repackaging, it seems like there is really a sessionstore which stores sessions and a pagestore which stores pages for a given session (that independently synchronized sublist). i'm not sure that's the best thing, but i am sure that it would be worth stepping back and thinking about how to make the abstraction as minimal and obvious as possible here.

Re: [Wicket-user] second level cache - why not to use ehcache
no there is not a page store per session There is only one sessionstore and one pagestore per application. what should be refactored a bit is the actual saving Previously it was really a simple thing that serialized the page and saved to disk Now those 2 operations are really divided and a special thread is introduced So a bit nicer layout so that people can reuse almost everything except the actual saving to disk (or to db) johan On 2/14/07, Jonathan Locke [EMAIL PROTECTED] wrote: i wonder if it wouldn't pay to stop and refactor this a little. besides repackaging, it seems like there is really a sessionstore which stores sessions and a pagestore which stores pages for a given session (that independently synchronized sublist). i'm not sure that's the best thing, but i am sure that it would be worth stepping back and thinking about how to make the abstraction as minimal and obvious as possible here.

Re: [Wicket-user] second level cache - why not to use ehcache
right. i wasn't talking about instances. only interfaces and method calls. conceptually, if you have a session that is a store of pages (the page map). you can ask the session for an interface that gives you pages. how that's implemented is probably as you suggest. although decoupling these two things would give you the flexibility of easily changing the store's structure. if you have enough sessions, it may pay to have a separate folder for each one to store page files in, for example.
