Re: [Wicket-user] Use of Tree Component
I am using the Tree component. Very nice! Thanks. It's a hard one to get right, but I hope it suffices. Question: would it be possible for the devs to rename the css from something general, prone to name clashing (i.e. the current css), to something more specific and less prone to conflict, like treeComponentCss or whatever? Yeah. I could use a scheme like I do with the wizard component: class=wicketExtensionsWizardOuterTable. Would that work? Out of curiosity: I noticed that the Swing tree model is being used. Interesting approach. Is this used a lot in Wicket? Well, we're trying to stick with general datastructures, such as List for ListView etc. I thought the TreeModel of Swing is quite complete, and has the additional advantage that you can reuse the model in Swing apps - ok, not very likely anyone will actually do that. Implementing a custom treemodel would have been easier in some ways, but I like the fact that TreeModel and friends comes with nice functionality e.g. to insert and delete nodes etc. Please help: I have a very large tree to render, so I only want to hold in memory the parts of the tree that are expanded (limiting expansion at any given level to one branch only). I also want to make sure that all the non-expanded branches are purged from memory. I would say, do this in the same fashion as you would do with Swing. Like I said above, the tree works well with model updates, so you can let your model hold the part of the tree you actually need. Which is I think the current state + all possible direct childs. When such a child is expanded, you expand the tree model with the childs of the node you just expanded. Would that work? Johan and Jonathan are the people with extensive Swing experience here; maybe they've got some alternative ideas on this. As a side note. I'm still waiting for someone to step in and make this tree or a subclass a nice DHTML/ Ajax enabled tree. There have been several unfinished initiatives of making DHTML tree (and a couple of custom trees that I know of that are used in projects, but that haven't been made publicly available). We have different opions about where the direction the tree should be heading amongst developers, where I seem to stand alone in my argument that Swing's model is the way to go in favor of a simplified custom model. So, it's good to read for a change people like the fact that the tree uses the Swing model :) Eelco --- All the advantages of Linux Managed Hosting--Without the Cost and Risk!

[Wicket-user] need to clarify: detached entities as parameters
I know we've been over this before but I've got to dredge it up one more time, just to be absolutely sure I'm doing this the best possible way. Say I've got a master/detail setup between two pages. Since I'm using EJB3 which is essentially Hibernate, I need to decide whether or not to detach detail data if the master data is already detached. Page A: Pulls a list of Orders and wraps the collection in a LoadableDetachableModel. Each, when displayed in a ListView has a link that points to a detail page for that Order, passing the Order as a parameter for PageB to use like so: add(new Link(new PageB(order)); Page B: Populates a series of Labels w/ the Order entity that was passed into the constructor from Page A. Here's where someone had told me before that I also need to make sure this Order entity is also detached. I'm not entirely clear on why I would need to do that? The EJB/Hibernate session from Page A should have been closed by the time I reach Page B and the entity passed into the constructor should now be Transient, i.e. detached already. I'm able to confirm this fact because if I alter the entity param on Page B and then try to persist it, I get an exception. If I merge it instead, it merges into a new session and persists to the database. So, can I use the entity in Page B or must it also be detached and treated as a model throughout the page? I'd prefer not to wrap it in another model since it's much easier to just access the elements of the entity directly vs. working w/ a model.

Hi,Sorry it took some time to respond - I sat down and wrote a somewhat simpletest program that I can redistribute if required.ok here is my first pass. i cannot reproduce the problem, so i am kinda
flying blind here - all i know for sure is that it compilesit seems to me that as soon as you change the page the browser dumps the old_javascript_, in my case looks like it also dumps any running ajax requests. i
tried both ie and ffox.i added a self upating counter that keeps updating every 1 sec and a link togo to another page, havent been able to catch the right timing i guessI did some more testing also. As I mentioned in my first e-mail, our setup
is *similar* to self updating timer. The difference to timer is that we have anapplet receiving events from server. The applet then executes _javascript_function to fire ajax update when needed.It looks like that the threads in applet continue to run for some time even
after link is clicked (ie. applet is not stopped immediately)and seem to be able to run _javascript_ on page also.At least using an applet here is the easiest way to reproduce the situation.(And I understand that we are bending wicket a lot here :) - but compared
to what we had earlier wicket+ajax is very elegant and simple)anyways, i am attaching the patch, let me know if it works for you and wecan take it from hereThe patch mostly works; however, there seems to be a small window where
two threads (one from click and other one from ajax) can be executing atDefaultRequestTargetResolverStrategy which still results in page expired.My test application is available at:
http://download.syncrontech.com/public/wicket-ajax-race.zipHow to test:- load ExpireTestPage1- click on page 2 link- click on to page 1. Without your Igor's patch, you'll get page expired almost always
With Igor's patch, it requires some rather mad and rapid clicking of links to getthe requests generated so that error still occurs. But it is still there.Ari S.- Original Message -

We already decided to put my modified version to production and if there are no side effects from my change we can keep it for some time.
in trunk (2.0) this is already fixed in the default setting because we refactored the pagemap and have now a different default pagemap and httpsessionstore.
You mean that if I would use 2.0 from trunk the problem would go away ? If so, would it be possible to back-port the new pagemap to 1.2 branch ? Not as default, but something that I could turn on
from application settings ? Another point: when 1.2 is released, someone else might also hit this problem so it might be necessary to implement some kind
of fix anyway (at least for us, some pages were almost unusable because of this as other pages worked quite ok - it seems that YMMV). Ari S.
