How is this method any different with our current Component.setParent(), called in Component.add() Then we still don't have the parent (==page) already available in the constructor.And what does that last part (flexibility lost) have to do with adding a parent in the constructor You just have to pass that thing through nothing more.johanOn 2/15/06, Gili [EMAIL PROTECTED] wrote:Instead of introducing extra arguments to the constructor, why not simply move all this logic into a new method?That is, introduce Component.bind(Component parent).

Re: [Wicket-user] Post 1.2 roadmap
You have a big problem when a class depends on the behavior of a sub-class during construction time. This is because sub-classes are initialized after the initialization of the base-class. When there is no dependency, there is no problem. So, although I recognize Gili's point in general, I think Johan is right here: just passing the thing can't be a serious problem. Erik.

Re: [Wicket-user] Post 1.2 roadmap
This is what seems the safest to me... - v1.2 : Stop adding features RC/Release it :-) - v1.3 : v1.2 + Constructor Change + /maybe/ minimal other (ajax?) changes...

Yes.

I agree with Igor that we should move to 1.5, and don't wait for a year to do it. Not everyone will be happy with it, but we'll have a very decent version out with 1.3 which we should support for a long time (by which I mean bug fixing, not so much back porting new features). Moving to 1.5 will eleminate a few of the weak features we still have and can't fix. As Wicket is all about Java code and strong typing, it sucks we can't have that strong typing in one of our major concepts yet - the model. With generics we can have this. I think that alone is worth the move, and as a lot of other frameworks - either for UI stuff or other purposes - already moved to 1.5, I don't think it is too early. We are already a year further since our first 1.5 discussions. Eelco --- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!

a bug reported against Retroweaver for anything like that. Retroweaver's
been used in all sorts of environments (including with native compilers)
without problem. Retroweaver's been used in production all over the

I'm not denying that it's possible that Tom found a bug in it (these

even be able to investigate it. Kind of annoying to hear someone be so

IIRC (it was a couple of months ago), it obviously did not check 1.5 API
usages (at least not correctly) and even generics constructs caused
mysterious (ClassCast-?) exceptions. I didn't tried it deeper, because I

I'm sure that won't be perfect for some people, but I think it is

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

Wicket
Re: [Wicket-user] Post 1.2 roadmap
we have considered both options when figuring out the solution. we called it init() instead of bind() but it was basically the same thing.here are some advantages of a constructor over an init() method:1) constructors are atomic 2) an exception thrown from a constructor will prevent the object from being created (security)3) constructor parameters are much easier to pass. if you have a parameter that you want to pass from a constructor you would have to store it as a field so it is available in init(), this makes things really really dirty and break encapsulation. 4) constructors insure the proper order of creation. you cant have things like. Panel p1=new Panel(); p2=new Panel(); p2.init(p1) == error because p1 hasnt been initted and bound to the page yet.5) constructors, as the name implies, are used for constructing things in java. 6) constructors give component creators the ability to use the good citizen patternso in the end using construcors leads to a much more concise and clear code both for component creators and component users. also saying things vague like its better because components can be javabeans doesnt mean much. why not give arguments as to /why/ it would be better to have components as javabeans.anyways, this is not what this thread was about. if anyone is interested in discussing any of the points above please start a different thread. -IgorOn 2/14/06, Gili [EMAIL PROTECTED] wrote: Instead of introducing extra arguments to the constructor, why notsimply move all this logic into a new method? That is, introduce Component.bind(Component parent). We'd benefit fromthe fact that Wicket components could become JavaBeans and method-basedbinding is more flexible than constructor-based binding. From past experience, whenever classes require arguments in theirconstructors there is always some flexibility lost. For example, youabsolutely cannot invoke any code before super() if you subclass such a class so if the value of one of the arguments needs to be calculated ormodified in any way prior to the super() call you're out of luck.GiliTimo Stamm wrote: Johan Compagner schrieb: that would be very hard to maintain. For example if you have a panel that is rewritten by using only the new parent in constructor params. And you add that in youre own webpage/panel that doesn't use that parent in constructor param. Then you get all kind of errors because the child panel expect to have it all but because of the hierarchy problem that we have then, he doesn't have it. So i do think it is all or nothing. I see, thanks for the explanation. -1 for constructor change. On 2/14/06, Timo Stamm [EMAIL PROTECTED] wrote: Martijn Dashorst schrieb:- constructor refactor Wow, that's a /major/ change and will probably effect every custom component and every application written using Wicket. I see the benefit of having a complete component hierarchy availably right at the initialization of a class. But wouldn't it suffice to just make the new constructors available, and put a clear statement in the API docs? Then maybe deprecate the public add() in the next major version, and drop it in 2.0 or something like that? This opens up a lot of better markup parsing strategies for the core.

Frank, I am assuming that you want to use something like the CompoundPropertyModel?

[Wicket-user] PropertyModel question
In Wicket 1.2, if an object has a public variable named property but no getProperty() / setProperty() methods, can we use the string property in constructing a PropertyModel? It seems that we could do this in Wicket 1.1, which used OGNL -- as OGNL mentions using a variable name if the getters/setters are absent. However, the JavaDoc for PropertyResolver in Wicket 1.2 does not mention finding aptly named instance variables. Is this an oversight in the documentation, or is this one of the infrequently used OGNL options that was sacrificed for efficiency?

RE: [Wicket-user] Component model question
Are there any guidelines written up on building reusable components in Wicket? Other than that one typically uses a Panel? For example, Ive decided that I need a panel that contains a DatePicker attached to a textbox, with a descriptive label and a secondary label to print warnings when an inappropriate date is selected (because this will appear on most all of my pages). Id like to retain the flexibility of assigning the date-textbox a model upon use of my panel, and to give the user the option of making something happen whenever the user changes the date. For hours Ive been sitting here, feeling like an idiot because I couldnt figure out how to do this seemingly simple thing. Maybe I should define a specialized model type or interface for my Panel, so that each component inside could be instantiated with a PropertyModel based on the Panels model. (Here, Im talking about the object containing the actual unwrapped data not another version of IModel). Then I could override the Date-TextBoxs wantChangeNotifications() and onModelChanged() methods to defer to those methods of the containing Panel -- which users of my Panel may override. Is this the way to do it? Ive read so much about the ease of abstraction in Wicket because one has all of Javas object-orientation at ones disposal, but its certainly not obvious to me how to take advantage of it.
[Wicket-user] DatePicker question with TextBox associated with input READONLY
A DatePicker is typically attached to a TextBox. In the FormInput example, a validator is also attached to the TextBox in case the user bypasses the DatePicker and types in something stupid. Could I simply attach my TextBox to an input READONLY=true field, so that the DatePicker can set the value but data cannot be typed in? Or will the READONLY attribute also foil the DatePicker?

[Wicket-user] CMS-like functionality with bookmarkable page
Hey everyone, I'm new to the users list and had a question about a certain type of design that I was hoping someone could shed some light on for me, I am most likely going about this completely bass-ackwards. The site I'm creating operates ontop of a very basic CMS system. In the database the admin can create a new page that consists of a name and then content (straight HTML), looks like this: page -- name: varchar(128) content: text So the idea of this is to develop a single bookmarkable page, let's call it ContentPage, that takes a name argument and before displaying, loads all the appropriate content from the DB, then injects it into the page. So I need the ContentPage to be bookmarkable, and to avoid too much information in the URL, I'm using an alias (content) for it. So the url would look something like this: http://mysite.com:8080/ContentPage.html?bookmarkablePage=contentname=/home From this, I want to look at the page parameter name get the value /home then pickup the content from the DB and place it into the page. Atleast that is the idea. I don't know if this is a down side or not, but the obvious side effect of this is that almost *every* page on the site is the ContentPage differing only by the page parameters name. As an example, here's a snippet of my nav bar and how the links look: - add(new BookmarkablePageLink(home, HomePage.class, createPageParameters(path, /home))); add(new BookmarkablePageLink(projects, HomePage.class, createPageParameters(path, /projects))); add(new BookmarkablePageLink(downloads, HomePage.class, createPageParameters(path, /downloads))); add(new BookmarkablePageLink(about, HomePage.class, createPageParameters(path, /about))); add(new BookmarkablePageLink(contact, HomePage.class, createPageParameters(path, /contact))); - ***createPageParameters just wraps the values in a PP and returns it*** So the problem I'm having is that any time I click any of my links in my page: -- a wicket:id=homeHome/a a wicket:id=projectsProjects/a a wicket:id=downloadsDownloads/a a wicket:id=aboutAbout/a a wicket:id=contactContact/a -- I get a Page Expired error. For example, clicking downloads my URL changes correctly to: http://localhost:8080/kallasoft/ContentPage.html?bookmarkablePage=contentpath=%2Fdownloads but I'm seeing a PageExpired. I'm betting this has to do with the fact that every page in my site is really the same page, but I don't understand the mechanics behind this and why it's barfing. Any help understanding this would be great, or pointing out if I'm doing something awful and possibly another way of addressing this.

Re: [Wicket-user] Post 1.2 roadmap
Replies below... Igor Vaynberg wrote: we have considered both options when figuring out the solution. we called it init() instead of bind() but it was basically the same thing. here are some advantages of a constructor over an init() method: 1) constructors are atomic Wicket components have always been thread-unsafe by design, so I fail to see how this is relevant. Do you plan on sharing Wicket components across threads anytime soon? Just define Component.isInit() and set it to true if a component has been initialized, and prevent double-initialization. 2) an exception thrown from a constructor will prevent the object from being created (security) Correct me if I'm wrong (you probably know more about this issue than me) but isn't the real security concern whether or not the Component may be rendered as opposed to whether or not it may be constructed? For example, normal users do not have admin access, so they should not be able to visit admin-only WebPages. You could enforce this security check at render time. 3) constructor parameters are much easier to pass. if you have a parameter that you want to pass from a constructor you would have to store it as a field so it is available in init(), this makes things really really dirty and break encapsulation. I think that is subjective. All JavaBeans work this way (if you need to use a variable later on, you are forced to store it as a field) but this has never bothered me. I already do this kind of thing with Wicket when I need a variable at render time (this happens quite often). In my view, this is no more ugly. 4) constructors insure the proper order of creation. you cant have things like. Panel p1=new Panel(); p2=new Panel(); p2.init(p1) == error because p1 hasnt been initted and bound to the page yet. The situation you describe exists with the current implementation (i.e. this is nothing new). IMHO this is common sense. I don't think anyone would find it confusing. 5) constructors, as the name implies, are used for constructing things in java. Right, but we're not constructing, we're binding. A WebPage floating in space is just fine. You should be able to use a constructor to create such an instance. Using Swing as an example (since Wicket is based upon it), you often create a component using a constructor and bind it using add() or setParent(). 6) constructors give component creators the ability to use the good citizen pattern so in the end using construcors leads to a much more concise and clear code both for component creators and component users. also saying things vague like its better because components can be javabeans doesnt mean much. why not give arguments as to /why/ it would be better to have components as javabeans. For one, many frameworks play very nicely with JavaBeans. If Wicket components were beans we could seamlessly plug them into things like XMLEncoder and the various bean APIs that manipulate them. anyways, this is not what this thread was about. if anyone is interested in discussing any of the points above please start a different thread. This discussion is regarding whether or not we should be passing the parent into the constructor as opposed to the current add() mechanism. I would argue that the current discussion is quite relevant in that we are trying to give our feedback on this proposal. I'm not arguing against the existence of constructors just for the sake of argument. Gili --- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!

using the constructor. Was there another reason for using ArrayListStack
over ArrayList which was not mentioned in the CVS commit log?

Re: [Wicket-user] Post 1.2 roadmap
1) constructors are atomic Wicket components have always been thread-unsafe by design, so I fail to see how this is relevant. Do you plan on sharing Wicket components across threads anytime soon? Just define Component.isInit() and set it to true if a component has been initialized, and prevent double-initialization. Atomic != threadsafe. See http://en.wikipedia.org/wiki/Atomicity. Either a component's construction completes including the parents it is added, or not. One of the side effects of the add method is that the hierarchical position of the component is postponed until it is added to a parent, and even then the action is not complete, as those components might still need to be added to their parents. 2) an exception thrown from a constructor will prevent the object from being created (security) Correct me if I'm wrong (you probably know more about this issue than me) but isn't the real security concern whether or not the Component may be rendered as opposed to whether or not it may be constructed? For example, normal users do not have admin access, so they should not be able to visit admin-only WebPages. You could enforce this security check at render time. It's just the concept of fail early. It is generally a good idea in programming to fail as early as possible if you know you are going to fail. Objects might be expensive to create etc. 3) constructor parameters are much easier to pass. if you have a parameter that you want to pass from a constructor you would have to store it as a field so it is available in init(), this makes things really really dirty and break encapsulation. I think that is subjective. All JavaBeans work this way (if you need to use a variable later on, you are forced to store it as a field) but this has never bothered me. I already do this kind of thing with Wicket when I need a variable at render time (this happens quite often). In my view, this is no more ugly. If you want to tighten things up and force users of your class to provide it's dependencies at construction time, requiring constructor arguments is a robust technique. This is not a new concept, and even has been one of the main battle arguments in the constructor vs property dependency IoC camp. We don't have to join that discussion though, as we are not building a managed IoC framework. 4) constructors insure the proper order of creation. you cant have things like. Panel p1=new Panel(); p2=new Panel(); p2.init(p1) == error because p1 hasnt been initted and bound to the page yet. The situation you describe exists with the current implementation (i.e. this is nothing new). IMHO this is common sense. I don't think anyone would find it confusing. I made mistakes with it. Why wouldn't anyone else? Furthermore, lots of times you don't own the whole component creation code, giving rise to more uncertainties. 5) constructors, as the name implies, are used for constructing things in java. Right, but we're not constructing, we're binding. A WebPage floating in space is just fine. You should be able to use a constructor to create such an instance. Using Swing as an example (since Wicket is based upon it), you often create a component using a constructor and bind it using add() or setParent(). As we want component creation and setting of parents to be atomic, we are not merely binding. A component floating into space has problems, particalarly if you depend on its place in the hierarchy in the constructor. This is not just theory. People are having troubles with this, especially when it comes to ajax/ javascript integration and component interaction. This discussion is regarding whether or not we should be passing the parent into the constructor as opposed to the current add() mechanism. I would argue that the current discussion is quite relevant in that we are trying to give our feedback on this proposal. I'm not arguing against the existence of constructors just for the sake of argument. No 'we' (the committers) decided on using the constructor pattern and were asking you about your opinion as to when this should be implement. Or actually, whether this change should be made together with the move to JDK 5. Here is what Martijn asked: quote 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? /quote Eelco --- This SF.net email is sponsored by: Splunk Inc.

Re: [Wicket-user] Post 1.2 roadmap
first of all we have already decided that this is going to happen. there was a vote and it passed. this is what the original posting by martijn implied, he asked for /when/ not /how/.second of all i asked you to not post any discussion of this to this thread, i really dont understand why this is so difficult. can you not follow simple directions? why do you add noise to what already is a busy thread? why should people who are interested in the outcome of this thread waste their time reading your off topic posts. my better judgement tells me to ignore your replies and not add any noise myself. but i am affraid that course of action is too implicit for you to understand, so i am making it very explicit hoping that the noise can stop at this. you are more then welcome to reply to this if you have anything further to say, but pelase do it in another thread.thank you,-IgorOn 2/15/06, Gili [EMAIL PROTECTED] wrote: Replies below...Igor Vaynberg wrote: we have considered both options when figuring out the solution. we called it init() instead of bind() but it was basically the same thing. here are some advantages of a constructor over an init() method: 1) constructors are atomicWicket components have always been thread-unsafe by design, so I failto see how this is relevant.

If Wicketcomponents were beans we could seamlessly plug them into things likeXMLEncoder and the various bean APIs that manipulate them. anyways, this is not what this thread was about. if anyone is interested in discussing any of the points above please start a different thread.This discussion is regarding whether or not we should be passing the parent into the constructor as opposed to the current add() mechanism.
