That seems EXTREMELY unlikely. If this were the case, I would think a lot of apps would have fairly major and constant problems with open file limits.

Re: [Wicket-user] Post 1.2 roadmap
I tend to agree... could we perhaps have another thread for a formal vote? I've read through this thread and I just don't see that many people who both don't want 1.5 and do want the constructor change.Perhaps a survey like: 1. I need the constructor change NOW, but don't want 1.52. I don't care about the constructor change, do them whenever you want3. I don't want either one (just to catch the obstinate types:))I honestly think the do them separate types were mostly just wanting the 1.5 delayed a bit, and don't really care if there's a formal release with just the constructor change or not (but, of course, just IMO).Thanks,Jesshttp://www.jroller.com/page/jsight/ On 2/16/06, Justin Lee [EMAIL PROTECTED] wrote: -BEGIN PGP SIGNED MESSAGE-Hash: RIPEMD160The constructor change is going to be disruptive enough that maybeswitching both at once wouldn't be so bad.That'd mean only twobranches to maintain which would be a lot less work on you guys.That'd be my vote.It sucks for those who can't upgrade to 1.5 yet, but youhave to make sure you're not making too much work for yourself.And 3branches could get ugly fast.Eelco Hillenius wrote: Yeah, that would mean supporting 1.2 and 1.3 as branches. 2.0 would be HEAD.

Re: [Wicket-user] Post 1.2 roadmap
I'm completely in favor of jumping to Wicket 2.0 and implementing both
of these changes with it. Java 5 support would be a really big plus
(esp. with tools like Retrotranslator and Retroweaver) for me as well.
I'm sure that won't be perfect for some people, but I think it is
reasonable to cut over now and keep a 1.2 version as a maintenance
branch.

All,
We are of course very busy finalizing Wicket 1.2, and we /really/ hope
to get it done soon. This will benefit everyone. So I want to take a
look beyond 1.2 and try to get some opinions on our roadmap, and
adjust where appropiate.
There are two very big things ahead of us:
- constructor refactor
we have reached a limit to the support we want to provide
for Ajax and javascript. In order to provide the best support
we need to know the markup id before it is available. Many
have been bitten by trying to retrieve an attribute from a
component tag in the page constructor.
We want to remedie this by removing the add() method,
and replacing it with an extra parameter in the component
constructor, which sets the parent of the component.
public MyPage() {
WebMarkupContainer c = new WebMarkupContainer(foo);
c.add(new TextField(bar1));
c.add(new Label(bar2));
c.add(new Label(bar3));
add(c);
}
will become:
public MyPage() {
WebMarkupContainer c = new WebMarkupContainer(this, foo);
new TextField(c, bar1);
new Label(c, bar2);
new Label(c, bar3);
}
This opens up a lot of better markup parsing strategies for the
core. We know this is a major API break, but we feel it is necessary
to implement it in order to move Wicket forward.
- java 5 support
This is something a lot of people are waiting for. I understand that
many people want, Igor states /need/, Java 5 support in Wicket.
There is also a negative side to this. Some, or even many of you,
can't move to java 1.5 as a server platform. We don't know how
many users this affects. Please give a response when you can't
move to 1.5. As Wicket is a volunteer effort, we can only support
so many projects. Supporting both a 1.4 and 1.5 project will
drain our resources too far, and won't be possible. So we have to
make a choice.
The questions I'm seeking answers to are the following:
- should the post 1.2 version of Wicket involve both changes?
- should we make different releases for either change, and thus
postponing 1.5 to
Wicket 3?
- how many of you still require for current or future projects to run
on JDK 1.4?
- how many would object to having a retroweaver build of a JDK 5 Wicket,
which
enables you to run 1.5 code on a 1.4 JRE?
Thanks for your answers,
Martijn

Yes. Oberg can make all the changes to GPL that he wants for his own branch of future modifications.

I would advise all the team members to read and follow the recent (this week) discussion started on the ServerSide about this exact subject:http://www.theserverside.com/news/thread.tss?thread_id=36156 This thread is already massive and contains besides very interesting and valuable opinions also a lot of rubbish as usually. As I said, INAL, but the one thing that's very clear to me from that discussion is that choosing the appropriate license *and* complying to it is not to be taken lightly and can be tricky to say the least. Using LGPL licensed code especially is very dangerous in my book, because everyone seems to have a different interpretation of it. Maybe the LGPL is crystal clear in legal terms in the end, but as long as so many people disagree about what it really means, I don't trust it... Most notably in the discussion on the ServerSide is the unexpected trick Rickard Öberg is now playing on JBoss by declaring all his original work within the JBoss codebase (which is a massive amount) to be GPL from now on:http://www.theserverside.com/news/thread.tss?thread_id=36156#182919 Checkout section 3) of the LGPL for a clarification. This might end up as being nonsense and of no consequence, and maybe not. I really don't know but I love to find out how this will work out. Anyways, for Wicket, I didn't know yet it already depends (and contains) LGPL code. Turns out the DatePicker embeds and uses the calendar _javascript_ library from http://dynarch.com/mishoo/calendar.epl. First of all, as result of that, I think we need to distribute the LGPL license with the Wicket extension library as required by section 1) of the license. Not complying with that is a violation of the LGPL. Furthermore, (and this one is very important to me as Apache committer) this also means usage of the Wicket extensions is no longer possible for Apache projects as the ASF doesn't allow any LGPL binding. While this is a restriction only from the ASF itself and not purely based on the ASL 2.0 license of Wicket (it *is* allowed to bind to LGPL if you want),many companies won't allow using the Wicket extensions anymore because they don't trust LGPL either. I've worked myself on a commercial project which didn't allow any LGPL based or linked software because they didn't trust that license and couldn't be sure about the consequences. Reading the discussion on theServerSide again reinforced that I have to agree on that assessment. So, I think I need to make my position clear on this matter. Binding Wicket extensions to LGPL (as it already does) makes it useless to me and many others. And binding Wicket core to LGPL would make the whole framework useless to me and many others. I do think it is important to be very careful about all this. Some choices can end up to have irreversible consequences and in my view seriously endanger the acceptance of Wicket... Eelco Hillenius wrote: Yeah, I don't know. I allways hated the licencing stuff. Wish there were just two licences.

But if someone would be so kind to explain the details/ in-outs that would be nice. It would really suck if when you choose for Apache 2, you couldn't use LPGL at all, and if you choose LGPL, you couldn't use Apache 2 at all. I'm pretty sure I speak for 95% percent of the programmers if I say I'm really not that into the details; as a customer I want to know whether I can ship it with commercial projects, and - maybe - whether I can ajust the source and ship it.

So the concern now is performance? Is this really meaningful? If there is a substantial performance penalty for it, wouldn't that just mean that Wicket is already slow?

[Wicket-user] Rich Text Editing Controls...
Just curious, does anyone have any experiences with good, easily customizable Rich Text Editing controls that could be integrated into Wicket? I've been tossing the idea around of integrating one (haven't gotten into evaluations yet) for a project, and would like to hear any first hand experiences. Of course, if anything comes of it code will be contributed back to the Wicket (FOSS license) community. Thanks, Jess

Re: [Wicket-user] Using JDK 1.5
I haven't followed Websphere that closely either lately, but I do think they still do this. I'd be very surprised to see a JDK 1.5 Websphere before the runtime is available for 1.5. Having said that, I would not expect it to take anywhere near 5 years. :)On 8/1/05, Gili [EMAIL PROTECTED] wrote: huh?? Do you really think that ibm waits for there own jre (if they are building it) when they want to support J2EE 5 in websphere?? J2EE 5 will heavily build in jre 5 features and j2ee will be out early next year. So that will be the big push for all Application Server vendors to fully support the 1.5 vm. We just have to wait a bit more. johanActually, yes this is what I was implying. I haven't followed Webspherein a while, but last time I looked IBM absolutely *did* wait for their own JDK before supporting newer features. In fact, this is part of theirmarketing strategy as they would always bundle Websphere with their JREsin order to get more people to use it.Has this changed over the past few years?
